Introduction

2.5. Addressing Health Inequities and Barriers to AF Management

1. Patients with AF, regardless of sex and gender diversity, race and ethnicity, or adverse social determinants of health (SDOH),* should be equitably offered guideline-directed stroke risk reduction therapies as well as rate or rhythm control strategies and LRFM as indicated to improve QOL and prevent adverse outcomes. (1, B-NR)
* Including lower income, lower education, inadequate or lack of insurance coverage, or rurality.

3. Shared Decision-Making in AF Management

1. In patients with AF, the use of evidence-based decision aids might be useful to guide stroke reduction therapy treatment decisions throughout the disease course to improve engagement, decisional quality, and patient satisfaction. (2b, B-R)
3594638

Management

4.2. Basic Evaluation

4.2.1. Basic Clinical Evaluation

1. In patients with newly diagnosed AF, a transthoracic echocardiogram to assess cardiac structure, laboratory testing to include a complete blood count, metabolic panel, and thyroid function, and testing to assess for other medical conditions associated with AF are recommended to determine stroke and bleeding risk factors, as well as underlying conditions that will guide further management. (1, B-NR)
3594638
2. In patients with newly diagnosed AF, protocolized testing for ischemia, acute coronary syndrome (ACS), and pulmonary embolism (PE) should not routinely be performed to assess the etiology of AF unless there are additional signs or symptoms to indicate those disorders. (3 - No Benefit, B-NR)
3594638

4.2.2. Rhythm Monitoring Tools and Methods

1. Among individuals without a known history of AF, it is recommended that an initial AF diagnosis be made by a clinician using visual interpretation of the electrocardiographic signals, regardless of the type of rhythm or monitoring device. (1, B-NR)
3594638
2. In patients with an intracardiac rhythm device capable of a diagnosis of AF, such as from an atrial pacemaker lead, a diagnosis of AF should only be made after it is visually confirmed by reviewing intracardiac tracings in order to exclude signal artifacts and other arrhythmias. (1, B-NR)
3594638
3. For patients who have had a systemic thromboembolic event without a known history of AF and in whom maximum sensitivity to detect AF is sought, an implantable cardiac monitor is reasonable. (2a, B-R)
3594638
4. Among patients with a diagnosis of AF, it is reasonable to infer AF frequency, duration, and burden using automated algorithms available from electrocardiographic monitors, implantable cardiac monitors, and cardiac rhythm devices with an atrial lead, recognizing that periodic review can be required to exclude other arrythmias. (2a, B-NR)
3594638

5. Among patients with AF in whom cardiac monitoring is advised, it is reasonable to recommend use of a consumer-accessible electrocardiographic device that provides a high-quality tracing to detect recurrences.

(2a, B-R)
3594638

5. Lifestyle and Risk Factor Modification for AF Management

5.1. Primary Prevention

1. Patients at increased risk of AF should receive comprehensive guideline-directed LRFM for AF, targeting obesity, physical inactivity, unhealthy alcohol consumption, smoking, diabetes, and hypertension. (1, B-NR)
3594638

5.2. Secondary Prevention: Management of Comorbidities and Risk Factors

5.2.1. Weight Loss in Individuals Who Are Overweight or Obese

1. In patients with AF who are overweight or obese (with BMI >27 kg/m2), weight loss is recommended, with an ideal target of at least 10% weight loss to reduce AF symptoms, burden, recurrence, and progression to persistent AF. (1, B-R)
3594638

5.2.2. Physical Fitness

1. In individuals with AF,* moderate to vigorous exercise training to a target of 210 minutes per week is recommended to reduce AF symptoms and burden, increase maintenance of sinus rhythm, increase functional capacity, and improve QOL. (1, B-R)
* In patients without AF related to excessive exercise training.
3594638

5.2.3. Smoking Cessation

1. Patients with a history of AF who smoke cigarettes should be strongly advised to quit smoking and should receive guideline-directed management and therapy (GDMT) for tobacco cessation to mitigate increased risks of AF-related cardiovascular complications and other adverse outcomes. (1, B-NR)
3594638

5.2.4. Alcohol Consumption

1. Patients with AF seeking a rhythm-control strategy should minimize or eliminate alcohol consumption to reduce AF recurrence and burden. (1, B-R)
3594638

5.2.5. Caffeine Consumption

1. For patients with AF, recommending caffeine abstention to prevent AF episodes is of no benefit, although it may reduce symptoms in patients who report caffeine triggers or worsens AF symptoms. (3 - No Benefit, B-NR)
3594638

5.2.8. Treatment of Hypertension

1. For patients with AF and hypertension, optimal BP control is recommended to reduce AF recurrence and AF-related cardiovascular events. (1, B-NR)
3594638

5.2.9. Sleep

1. Among patients with AF, it may be reasonable to screen for obstructive sleep apnea, given its high prevalence in patients with AF, although the role of treatment of SDB to maintain sinus rhythm is uncertain. (2b, B-NR)
3594638

5.2.10. Comprehensive Care

1. Patients with AF should receive comprehensive care addressing guideline-directed LRFM, AF symptoms, risk of stroke, and other associated medical conditions to reduce AF burden, progression, or consequences. (1, A)
3594638
2. In patients with AF, use of clinical care pathways, such as nurse-led AF clinics, is reasonable to promote comprehensive, team-based care and to enhance adherence to evidence-based therapies for AF and associated conditions. (2a, B-R)
3594638

6. Prevention of Thromboembolism

6.1. Risk Stratification Schemes

1. Patients with AF should be evaluated for their annual risk of thromboembolic events using a validated clinical risk score, such as CHA2DS2-VASc. (1, B-NR)
3594638
2. Patients with AF should be evaluated for factors that specifically indicate a higher risk of bleeding, such as previous bleeding and use of drugs that increase bleeding risk, in order to identify possible interventions to prevent bleeding on anticoagulation. (1, B-NR)
3594638
3. Patients with AF at intermediate annual risk of thromboembolic events by risk scores (eg, equivalent to CHA2DS2-VASc score of 1 in men or 2 in women), who remain uncertain about the benefit of anticoagulation, can benefit from consideration of factors that might modify their risk of stroke to help inform the decision.* (2a, C-LD)
* Factors may include AF burden or other features in Table 3.
3594638
4. In patients who are deemed at high risk for stroke, bleeding risk scores should not be used in isolation to determine eligibility for oral anticoagulation but instead to identify and modify bleeding risk factors and to inform medical decision-making. (3 - No Benefit, B-NR)
3594638

6.2. Risk-Based Selection of Oral Anticoagulation: Balancing Risks and Benefits

1. In patients diagnosed with AF who have an estimated annual risk of stroke or thromboembolic events ≥2%, selection of therapy to reduce the risk of stroke should be based on the risk of thromboembolism, regardless of whether the AF pattern is paroxysmal, persistent, long-standing persistent, or permanent. (1, B-R)
3594638

2. In patients with AF at risk for stroke, reevaluation of the need for and choice of stroke risk reduction therapy at periodic intervals is recommended to reassess stroke and bleeding risk, net clinical benefit, and proper dosing.

(1, B-NR)
3594638

6.3. Oral Anticoagulants

6.3.1. Antithrombotic Therapy

1. For patients with AF and an estimated annual thromboembolic risk of ≥2%/year (eg, CHA2DS2-VASc score of ≥2 in men and ≥3 in women), anticoagulation is recommended to prevent stroke and systemic thromboembolism. (1, A)
3594638
2. In patients with AF who do not have a history of moderate to severe rheumatic mitral stenosis or a mechanical heart valve, and who are candidates for anticoagulation, direct oral anticoagulants (DOACs) are recommended over warfarin to reduce the risk of mortality, stroke, systemic embolism, and intracranial hemorrhage (ICH). (1, A)
3594638
3. For patients with AF and an estimated annual thromboembolic risk of ≥1% but <2%/year (equivalent to CHA2DS2-VASc score of 1 in men and 2 in women), anticoagulation is reasonable to prevent stroke and systemic thromboembolism. (2a, A)
3594638
4. In patients with AF who are candidates for anticoagulation and without an indication for antiplatelet therapy (APT), aspirin either alone or in combination with clopidogrel as an alternative to anticoagulation is not recommended to reduce stroke risk. (3 - Harm, B-R)
3594638
5. In patients with AF without risk factors for stroke, aspirin monotherapy for prevention of thromboembolic events is of no benefit. (3 - No Benefit, B-NR)
3594638

6.3.1.1. Considerations in Managing Anticoagulants

1. For patients with AF receiving DOACs, optimal management of drug interactions is recommended for those receiving concomitant therapy with interacting drugs, especially CYP 3A4 and/or p-glycoprotein inhibitors or inducers (see Table 13). (1, C-LD)
3594638
2. For patients with AF receiving warfarin*, a target INR between 2 and 3 is recommended, as well as optimal management of drug-drug interactions, consistency in vitamin K dietary intake, and routine INR monitoring to improve time in therapeutic range and to minimize risks of preventable thromboembolism or major bleeding. (1, B-R)
3594638
3. For patients with AF, nonevidence-based doses of DOACs should be avoided to minimize risks of preventable thromboembolism or major bleeding and to improve survival. (3 - Harm, B-NR)
3594638
* Excludes patients with mechanical valves.

6.4. Silent AF and Stroke of Undetermined Cause

1. In patients with stroke or TIA of undetermined cause, initial cardiac monitoring, and, if needed, extended monitoring with an implantable loop recorder are reasonable to improve detection of AF. (2a, B-R)
3594638

6.4.1. Oral Anticoagulation for Device-Detected Atrial High-Rate Episodes Among Patients Without a Prior Diagnosis of AF

1. For patients with a device-detected atrial high-rate episode (AHRE) lasting ≥24 hours and with a CHA2DS2-VASc score ≥2 or equivalent stroke risk, it is reasonable to initiate oral anticoagulation within a SDM framework that considers episode duration and individual patient risk. (2a, B-NR)
3594638
2. For patients with a device-detected AHRE lasting between 5 minutes and 24 hours and with a CHA2DS2-VASc score ≥3 or equivalent stroke risk, it may be reasonable to initiate anticoagulation within a SDM framework that considers episode duration and individual patient risk. (2b, B-NR)
3594638
3. Patients with a device-detected AHRE lasting <5 minutes and without another indication for oral anticoagulation should not receive oral anticoagulation. (3 - No Benefit, B-NR)
3594638

6.5.1. Percutaneous Approaches to Occlude the Left Atrial Appendage (LAA)

1. In patients with AF, a moderate to high risk of stroke (CHAD2DS2-VASc score ≥2), and a contraindication (Table 14) to long-term oral anticoagulation due to a nonreversible cause, percutaneous LAAO (pLAAO) is reasonable. (2a, B-NR)
3594638
2. In patients with AF and a moderate to high risk of stroke and a high risk of major bleeding on oral anticoagulation, pLAAO may be a reasonable alternative to oral anticoagulation based on patient preference, with careful consideration of procedural risk and with the understanding that the evidence for oral anticoagulation is more extensive. (2b, B-R)
3594638

6.5.2. Cardiac Surgery — LAA Exclusion/Excision

1. In patients with AF undergoing cardiac surgery with a CHAD2DS2-VASc score ≥2 or equivalent stroke risk, surgical LAA exclusion, in addition to continued anticoagulation, is indicated to reduce the risk of stroke and systemic embolism. (1, A)
3594638
2. In patients with AF undergoing cardiac surgery and LAA exclusion, a surgical technique resulting in absence of flow across the suture line and a stump of <1 cm as determined by intraoperative transesophageal echo should be used. (1, A)
3594638
3. In patients with AF undergoing cardiac surgery with CHAD2DS2-VASc score ≥2 or equivalent stroke risk, the benefit of surgical LAA exclusion in the absence of continued anticoagulation to reduce the risk of stroke and systemic embolism is uncertain. (2b, A)
3594638

6.6 Active Bleeding on Anticoagulant Therapy and Reversal Drugs

1. In patients with AF receiving dabigatran who develop life-threatening bleeding, treatment with idarucizumab is recommended to rapidly reverse dabigatran’s anticoagulation effect. (1, B-NR)
3594638
2. In patients with AF receiving dabigatran who develop life-threatening bleeding, treatment with activated prothrombin complex concentrate (PCC) is reasonable to reverse dabigatran’s anticoagulation effect if idarucizumab is not available. (2a, C-LD)
3594638
3. In patients with AF receiving factor Xa inhibitors who develop life-threatening bleeding, treatment with
either andexanet alfa (apixaban or rivaroxaban*, edoxaban†) (1, B-NR)
3594638
or 4-factor prothrombin complex concentrate.† (1, C-LD)
3594638
is recommended to rapidly reverse factor Xa inhibitor’s anticoagulation effect.
4. In patients with AF receiving warfarin who develop life-threatening bleeding, treatment with 4-factor prothrombin complex concentrate (if available) in addition to intravenous (IV) vitamin K is recommended to rapidly achieve INR correction over fresh frozen plasma and intravenous vitamin K treatment. (1, A)
3594638
5. In patients with AF who develop major GI bleeding, resumption of oral anticoagulation therapy may be reasonable after correction of reversible causes of bleeding and reassessment of its long-term benefits and risks with a multidisciplinary team approach during SDM with patients. (2b, B-NR)
3594638

6.6.1. Management of Patients with AF and Intracranial Hemorrhage

1. In patients with AF and conditions associated with very high risk of thromboembolic events (>5%/year), such as rheumatic heart disease or a mechanical heart valve, early (1–2 weeks) resumption of anticoagulation after ICH is reasonable to reduce the risk of thromboembolic events. (2a, C-LD)
3594638
2. In patients with AF and ICH, delayed (4-8 weeks) resumption of anticoagulation may be considered to balance the risks of thromboembolic and hemorrhagic complications after careful risk benefit assessment. (2b, C-LD)
3594638
3. In patients with AF and conditions associated with high risk of recurrent ICH (eg, cerebral amyloid angiopathy) anticoagulation-sparing strategies (eg, LAAO) may be considered to reduce the risk of recurrent hemorrhage. (2b, B-NR)
3594638

6.7. Periprocedural Management

1. In patients with AF (excluding those with recent stroke or TIA, or a mechanical valve) and on oral anticoagulation with
either warfarin*
(1, B-R)
3594638
or DOAC†
(1, B-NR)
and who are scheduled to undergo an invasive procedure or surgery, temporary cessation of oral anticoagulation without bridging anticoagulation is recommended.
3594638
2. In patients with AF on warfarin anticoagulation and an annual predicted risk of thromboembolism of ≥5% undergoing PM or defibrillator implantation or generator change, continued anticoagulation is recommended in preference to interruption of warfarin and bridging anticoagulation with heparin to reduce the risk of pocket hematoma. (1, A)
3594638
3. In patients with AF with CHA2DS2-VASc score ≥2 or equivalent risk of stroke, on DOAC anticoagulation and undergoing PM or defibrillator implantation or generator change, either uninterrupted or interrupted DOAC is reasonable. (2a, A)
3594638
4. In patients with AF on DOAC anticoagulation and scheduled to undergo an invasive procedure or surgery that cannot be performed safely on uninterrupted anticoagulation, the timing of interruption of DOAC should be guided by the specific agent, renal function, and the bleeding risk of the procedure (Table 18). (1, B-NR)
3594638
5. In patients with AF on DOAC anticoagulation that has been interrupted for an invasive procedure or surgery, in general, resumption of anticoagulation the day after low bleeding risk surgery and between the evening of the second day and the evening of the third day after high bleeding risk surgery is reasonable, as long as hemostasis has been achieved and further bleeding is not anticipated. (2a, B-NR)
3594638
6. In patients with AF on warfarin anticoagulation, who are undergoing surgeries or procedures for which they are holding warfarin, except in patients with mechanical valve or recent stroke or TIA, bridging anticoagulation with low-molecular-weight heparin should not be administered. (3 - Harm, B-R)
3594638

6.8. Anticoagulation in Specific Populations

6.8.1. AF Complicating Acute Coronary Syndrome or Percutaneous Coronary Intervention

1. In patients with AF and an increased risk for stroke who undergo PCI, DOACs are preferred over VKAs in combination with APT to reduce the risk of clinically relevant bleeding. (1, A)
3594638
2. In most patients with AF who take oral anticoagulation and undergo PCI, early discontinuation of aspirin (1–4 wk) and continuation of dual antithrombotic therapy (DAT) with OAC and a P2Y12 inhibitor is preferred over triple therapy (OAC, P2Y12 inhibitor, and aspirin) to reduce the risk of clinically relevant bleeding. (1, A)
3594638

6.8.2. Chronic Coronary Disease (CCD)

1. In patients with AF and CCD (beyond 1 year after revascularization or CAD not requiring coronary revascularization) without history of stent thrombosis, oral anticoagulation monotherapy is recommended over the combination therapy of OAC and single APT (aspirin or P2Y12 inhibitor) to decrease risk of major bleeding. (1, B-R)
3594638

6.8.3. Peripheral Artery Disease (PAD)

1. In patients with AF and concomitant stable PAD, monotherapy oral anticoagulation is reasonable over dual therapy (anticoagulation plus aspirin or P2Y12 inhibitors) to reduce the risk of bleeding. (2a, B-NR)
3594638

6.8.4. Chronic Kidney Disease/Kidney Failure

1. For patients with AF at elevated risk for stroke and CKD stage 3, treatment with warfarin or, preferably, evidence-based doses of direct thrombin or factor Xa inhibitors (Table 19) is recommended to reduce the risk of stroke. (1, B-R)
3594638
2. For patients with AF at elevated risk for stroke and CKD stage 4, treatment with warfarin or labeled doses of DOACs is reasonable to reduce the risk of stroke. (2a, B-NR)
3594638
3. For patients with AF at elevated risk for stroke and who have end-stage CKD (CrCl <15 mL/min) or are on dialysis, it might be reasonable to prescribe warfarin (INR 2.0–3.0) or evidence-based dose of apixaban for oral anticoagulation to reduce the risk of stroke. (2b, B-NR)
3594638

6.8.5. AF in Valvular Heart Disease

1. In patients with rheumatic mitral stenosis or mitral stenosis of moderate or greater severity and history of AF, long-term anticoagulation with warfarin is recommended over DOACs, independent of the CHA2DS2-VASc score to prevent cardiovascular events, including stroke or death. (1, B-R)
3594638
2. In patients with AF and valve disease other than moderate or greater mitral stenosis or a mechanical heart valve, DOACs are recommended over VKAs. (1, B-NR)
3594638

6.8.6. Anticoagulation of Typical Atrial Flutter

1. For patients with AFL, anticoagulant therapy is recommended according to the same risk profile used for AF. (1, B-NR)
3594638
2. In patients with AFL who undergo successful cardioversion or ablation resulting in restoration of sinus rhythm, anticoagulation should be continued for at least 4 weeks postprocedure. (1, C-LD)
3594638
3.L who have undergone successful cavotricuspid isthmus (CTI) ablation and have had AFL ablation should receive ongoing oral anticoagulation postablation as indicated for AF. (1, A)
3594638
4. Patients with typical AFL who have undergone successful CTI ablation and are deemed to be at high thromboembolic risk, without any known prior history of AF, should receive close follow-up and arrhythmia monitoring to detect silent AF if they are not receiving ongoing anticoagulation in view of significant risk of AF. (1, B-NR)
3594638
5.L who have undergone successful CTI ablation without any known prior history of AF who are at high risk for development of AF (eg, LA enlargement, inducible AF, COPD, HF), it may be reasonable to prescribe long-term anticoagulation if thromboembolic risk assessment suggests high risk (>2% annual risk) for stroke. (2b, B-NR)
3594638
* This section refers to typical right-sided (CTI-dependent) AFL. Left-Ls or ATs that develop after ablation of AF should be anticoagulated and managed in a manner similar to AF.
Define typical and atypical AFL elsewhere:
  • “Typical” AFL is defined as either typical counterclockwise AFL when the macroreentrant circuit is dependent on the CTI using the isthmus from the patient’s right to left or typical clockwise AFL when the macroreentrant circuit is dependent on the CTI and uses this isthmus from the patient’s left to right.
  • “Atypical” AFL is not dependent on the CTI and may arise from a macroreentrant circuit in the LA, such as perimitral or LA roof flutter or could be dependent on scar from prior ablation or surgery.

7. Rate Control

7.1. Broad Considerations for Rate Control

1. In patients with AF, SDM with the patient is recommended to discuss rhythm- vs. rate-control strategies (taking into consideration clinical presentation, comorbidity burden, medication profile, and patient preferences), discuss therapeutic options, and for assessing long-term benefits. (1, B-NR)
3594638
2. In patients with AF without HF who are candidates for select rate-control strategies, heart rate target should be guided by underlying patient symptoms, in general aiming at a resting heart rate of <100 to 110 bpm. (2a, B-R)
3594638

7.2.1. Acute Rate Control

1. In patients with AF with rapid ventricular response who are hemodynamically stable, beta blockers or nondihydropyridine calcium channel blockers (verapamil, diltiazem, provided that EF >40%) are recommended for acute rate control (Figure 17). (1, B-R)
3594638
2. In patients with AF with rapid ventricular response in whom beta blockers and nondihydropyridine calcium channel blockers are ineffective or contraindicated, digoxin can be considered for acute rate control, either alone or in combination with the aforementioned agents. (2a, B-R)
3594638
3. In patients with AF with rapid ventricular response, the addition of intravenous magnesium to standard rate-control measures is reasonable to achieve and maintain rate control. (2a, A)
3594638
4. In patients with AF with rapid ventricular response who are critically ill and/or in decompensated HF in whom beta blockers and nondihydropyridine calcium channel blockers are ineffective or contraindicated, intravenous amiodarone may be considered for acute rate control.* (2b, B-NR)
* Consider the risk of cardioversion and stroke when using amiodarone as a rate-control agent.
3594638
5. In patients with AF with rapid ventricular response and known moderate or severe LV systolic dysfunction with or without decompensated HF, intravenous nondihydropyridine calcium channel blockers should not be administered. (3 - Harm, B-NR)
3594638

7.2.2. Long-Term Rate Control

1. In patients with AF, beta blockers or nondihydropyridine calcium-channel blockers (diltiazem, verapamil) are recommended for long-term rate control with the choice of agent according to underlying substrate and comorbid conditions. (1, B-NR)
3594638
2. For patients with AF in whom measuring serum digoxin levels is indicated, it is reasonable to target levels <1.2 ng/mL. (2a, B-NR)
3594638
3. In patients with AF and HF symptoms, digoxin is reasonable for long-term rate control in combination with other rate-controlling agents, or as monotherapy if other agents are not preferred, not tolerated, or contraindicated. (2a, B-R)
3594638
4. In patients with AF and left ventricular ejection fraction (LVEF) <40%, nondihydropyridine calcium channel-blocking drugs should not be administered given their potential to exacerbate HF. (3 - Harm, C-LD)
3594638
5. In patients with permanent AF who have risk factors for cardiovascular events, dronedarone should not be used for long-term rate control. (3 - Harm, B-R)
3594638

7.3. Atrioventricular Nodal Ablation (AVNA)

1. In patients with AF and a persistently rapid ventricular response who undergo AVNA, initial PM lower rate programming should be 80 to 90 bpm to reduce the risk of sudden death. (1, C-LD)
3594638
2. In patients with AF and uncontrolled rapid ventricular response refractory to rate-control medications (who are not candidates for or in whom rhythm control has been unsuccessful), AVNA can be useful to improve symptoms and QOL. (2a, B-R)
3594638
4. In patients with AF with normal EF undergoing AVNA, conduction system pacing (CSP) of the His bundle or left bundle area may be reasonable. (2b, C-LD)
3594638

8. Rhythm Control

8.1. Goals of Therapy With Rhythm Control

1. In patients with reduced LV function and persistent (or high burden) AF, a trial of rhythm control should be recommended to evaluate whether AF is contributing to the reduced LV function. (1, B-R)
3594638
2. In patients with symptomatic AF, rhythm control can be useful to improve symptoms. (2a, B-R)
3594638
3. In patients with a recent diagnosis of AF (<1 year), rhythm control can be useful to reduce hospitalizations, stroke, and mortality. (2a, B-R)
3594638
4. In patients with AF and HF, rhythm control can be useful for improving symptoms and improving outcomes, such as mortality and hospitalizations for HF and ischemia. (2a, B-R)
3594638
5. In patients with AF, rhythm-control strategies can be useful to reduce the likelihood of AF progression. (2a, B-NR)
3594638
6. In patients with AF where symptoms associated with AF are uncertain, a trial of rhythm control (eg, cardioversion or pharmacological therapy) may be useful to determine what if any symptoms are attributable to AF. (2b, C-LD)
3594638

7. In patients with AF, rhythm-control strategies may be useful to reduce the likelihood of development of dementia or worsening cardiac structural abnormalities.

(2b, B-NR)
3594638

8.2. Electrical and Pharmacological Cardioversion

8.2.1. Prevention of Thromboembolism in the Setting of Cardioversion

1. In patients with AF duration of ≥48 hours, a 3-week duration of uninterrupted therapeutic anticoagulation or imaging evaluation to exclude intracardiac thrombus is recommended before elective cardioversion. (1, B-R)
3594638

2. In patients with AF undergoing cardioversion, therapeutic anticoagulation should be established before cardioversion and continued for at least 4 weeks afterwards without interruption to prevent thromboembolism.

(1, B-NR)
3594638
3. In patients with AF in whom cardioversion is deferred due to LAA thrombus detected on precardioversion imaging, therapeutic anticoagulation should be instituted for at least 3 to 6 weeks, after which imaging should be repeated before cardioversion. (1, C-LD)
3594638

4. In patients with AF and prior LAAO who are not on anticoagulation, imaging evaluation to assess the adequacy of LAAO and exclude device-related thrombosis before cardioversion may be reasonable.

(2b, B-NR)
3594638
5. In patients with AF and prior LAAO with residual leak, pericardioversion anticoagulation may be considered and continued thereafter. (2b, C-LD)
3594638

6. In patients with reported AF duration of <48 hours (not in the setting of cardiac surgery) and who are not on anticoagulation, precardioversion imaging to exclude intracardiac thrombus may be considered in those who are at elevated thromboembolic risk (CHA2DS2-VASc score ≥2 or equivalent).

(2b, C-LD)
3594638
7. In patients with low thromboembolic risks (CHA2DS2-VASc 0–1 or equivalent) and AF duration of <12 hours, the benefit of precardioversion imaging or pericardioversion anticoagulation is uncertain given the low incidence of pericardioversion thromboembolic events in this population. (2b, C-LD)
3594638

8.2.2. Electrical Cardioversion

1. In patients with hemodynamic instability attributable to AF, immediate electrical cardioversion should be performed to restore sinus rhythm. (1, C-LD)
3594638
2. In patients with AF who are hemodynamically stable, electrical cardioversion can be performed as initial rhythm-control strategy or following failed pharmacological cardioversion. (1, B-R)
3594638
3. In patients with AF undergoing electrical cardioversion, energy delivery should be confirmed to be synchronized to the QRS to reduce the risk of inducing ventricular fibrillation (VF). (1, C-LD)
3594638
4. For patients with AF undergoing elective electrical cardioversion, the use of biphasic energy of at least 200 J as initial energy can be beneficial to improve success of initial electrical shock. (2a, B-R)
3594638
5. In patients with AF undergoing elective cardioversion, with longer duration of AF or failed initial shock, optimization of electrode vector, use of higher energy, and pretreatment with AADs can facilitate success of electrical cardioversion. (2b, C-LD)
3594638

6. In patients with obesity and AF, use of manual pressure augmentation and/or further escalation of electrical energy may be beneficial to improve success of electrical cardioversion.

(2b, C-LD)

3594638
3. For patients with AF, intravenous amiodarone is reasonable for pharmacological cardioversion, although time to conversion is generally longer than with other agents (8–12 hours). (2a, A)
3594638

4. For patients with recurrent AF occurring outside the setting of a hospital, the “pill-in-the-pocket” (PITP) approach with a single oral dose of flecainide or propafenone, with a concomitant AV nodal blocking agent, is reasonable for pharmacological cardioversion if previously tested in a monitored setting.

(2a, A)
3594638
5. For patients with AF, use of intravenous procainamide may be considered for pharmacological cardioversion when other intravenous agents are contraindicated or not preferred. (2b, B-R)

3594638
4. For patients with AF without significant baseline QT interval prolongation, uncorrected hypokalemia or hypomagnesemia, use of dofetilide is reasonable for long-term maintenance of sinus rhythm, with proper dose selection based on kidney function and close monitoring of the QT interval, serum potassium and magnesium concentrations, and kidney function. (2a, A)
3594638
5. For patients with AF and normal LV function, use of low-dose amiodarone (100–200 mg/d) is reasonable for long-term maintenance of sinus rhythm, but in view of its adverse effect profile should be reserved for patients in whom other rhythm control strategies are ineffective, not preferred, or contraindicated. (2a, A)
3594638
6. For patients with AF without significant baseline QT interval prolongation, hypokalemia, hypomagnesemia, or bradycardia, use of sotalol may be considered for long-term maintenance of sinus rhythm, with proper dose selection based on kidney function and close monitoring of the QT interval, heart rate, serum potassium and magnesium concentrations, and kidney function. (2b, A)
3594638

7. In patients with prior MI and/or significant structural heart disease, including HFrEF (LVEF ≤40%), flecainide and propafenone should not be administered to due to the risk of worsening HF, potential proarrhythmia, and increased mortality.

(3 - Harm, B-R)
3594638
8. For patients with AF, dronedarone should not be administered for maintenance of sinus rhythm to those with New York Heart Association (NYHA) class III and IV HF or patients who have had an episode of decompensated HF in the past 4 weeks, due to the risk of increased early mortality associated with worsening HF. (3 - Harm, B-R)
3594638

8.3.2. Inpatient Initiation of Antiarrhythmic Agents

1. Patients with AF who are initiating, increasing the dose of, or reinitiating dofetilide therapy should be admitted for a minimum of 3 days to a facility that can provide continuous electrocardiographic monitoring, calculations of CrCl, and cardiac resuscitation, given the potential for proarrhythmia. (1, A)
3594638
2. In patients with AF, it is reasonable to initiate sotalol therapy in a facility that can provide continuous electrocardiographic monitoring, calculations of CrCl, and cardiac resuscitation, given the potential for proarrhythmia and bradycardia. (2a, B-R)
3594638
3. In patients with AF who are initiating PITP dosing of flecainide and propafenone with concomitant AV nodal blocking drugs, it is reasonable to receive the first dose in a facility that can provide continuous electrocardiographic monitoring, given the potential for proarrhythmia. (2a, B-NR)

3594638

8.4.1. Patient Selection

8.4.2. Techniques and Technologies for AF Catheter Ablation

1. In patients undergoing ablation for AF, pulmonary vein isolation (PVI) is recommended as the primary lesion set for all patients unless a different specific trigger is identified. (1, A)
3594638
2. In patients undergoing ablation for AF, the value of other endpoints beyond PVI such as noninducibility and ablation of additional anatomic ablation targets (eg, posterior wall, sites, low voltage areas, complex fractionated electrograms, rotors) is uncertain. (2b, B-R)
3594638

8.4.3. Management of Recurrent AF After Catheter Ablation

1. In patients with recurrent symptomatic AF after catheter ablation, repeat catheter ablation or AAD therapy is useful to improve symptoms and freedom from AF. (1, B-NR)
3594638
2. In some patients who have undergone catheter ablation of AF, short-term AAD therapy after ablation can be useful to reduce early recurrences of atrial arrhythmia and hospitalization. (2a, A)
3594638

8.4.4. Anticoagulation Therapy Before and After Catheter Ablation

1. In patients undergoing catheter ablation of AF on warfarin, catheter ablation should be performed on uninterrupted therapeutic anticoagulation with a goal INR of 2.0 to 3.0. (1, B-NR)
3594638
2. In patients on a DOAC undergoing catheter ablation of AF, catheter ablation should be performed with either continuous or minimally interrupted oral anticoagulation. (1, A)
3594638
3. In patients who have undergone catheter ablation of AF, oral anticoagulation should be continued for at least 2 to 3 months after the procedure with a longer duration determined by underlying risk. (1, B-NR)
3594638
4. In patients who have undergone catheter ablation of AF, continuation of longer-term oral anticoagulation should be dictated according to the patients’ stroke risk (eg, CHA2DS2-VASc score ≥2). (1, B-NR)
3594638

8.4.5. Complications Following AF Catheter Ablation

8.5. Role of Pacemakers and Implantable Cardioverter-Defibrillators for the Prevention and Treatment of AF

1. In patients with bradycardia requiring cardiac-implanted electronic devices who have normal AV conduction, device selection and programming strategies to maintain AV synchrony and minimize ventricular pacing should be used to reduce the incidence and progression of AF. (1, A)
3594638
2. In selected patients with a pacemaker and symptomatic atrial tachyarrhythmias, antitachycardia atrial pacing and ventricular pacing minimization may be useful for reducing symptoms. (2b, B-NR)
3594638
3. In patients with AF who require significant ventricular pacing, conduction system pacing may be useful to reduce progression of AF. (2b, C-LD)
3594638

3594638

9. Management of Patients With HF
9.1. General Considerations for AF and HF

9.2. Management of AF in Patients With HF*

1. In patients who present with a new diagnosis of HFrEF and AF, arrhythmia-induced cardiomyopathy should be suspected, and an early and aggressive approach to AF rhythm control is recommended. (1, B-NR)
3594638
2. In appropriate patients with AF and HFrEF who are on GDMT, and with reasonable expectation of procedural benefit (Figure 24), catheter ablation is beneficial to improve symptoms, QOL, ventricular function, and cardiovascular outcomes. (1, A)
3594638
3. In appropriate patients with symptomatic AF and heart failure with preserved ejection fraction (HFpEF) with reasonable expectation of benefit, catheter ablation can be useful to improve symptoms and improve QOL. (2a, B-NR)
3594638
4. In patients with AF and HF, digoxin is reasonable for rate control, in combination with other rate-controlling agents or as monotherapy if other agents are not tolerated. (2a, B-R)
3594638
5. In patients with AF and HF with rapid ventricular rates in whom beta blockers or calcium channel blockers are contraindicated or ineffective, intravenous amiodarone is reasonable for acute rate control.† (2a, B-NR)
3594638
6. In patients with AF, HFrEF (LVEF <50%), and refractory rapid ventricular response who are not candidates for or in whom rhythm control has failed, AVNA and biventricular pacing therapy can be useful to improve symptoms, QOL, and EF. (2a, B-R)
3594638
7. In patients with AF, HF, and implanted biventricular pacing therapy in whom an effective pacing percentage cannot be achieved with pharmacological therapy, AVNA can be beneficial to improve functional class, reduce the risk of ICD shock, and improve survival. (2a, B-NR)
3594638
8. In patients with AF-induced cardiomyopathy who have recovered LV function, long-term surveillance can be beneficial to detect recurrent AF in view of the high risk of recurrence of arrhythmia-induced cardiomyopathy. (2a, B-NR)
3594638
9. In patients with suspected AF-induced cardiomyopathy or refractory HF symptoms undergoing pharmacological rate-control therapy for AF, a stricter rate-control strategy (target heart rate <80 bpm at rest and <110 bpm during moderate exercise) may be reasonable. (2b, B-NR)
3594638
10. In patients with AF and HFrEF who undergo AVNA, conduction system pacing of the His bundle or left bundle branch area may be reasonable as an alternative to biventricular pacing to improve symptoms, QOL, and LV function. (2b, C-LD)
3594638
11. In patients with AF and known LVEF <40%, nondihydropyridine calcium channel-blocking drugs should not be administered given their potential to exacerbate HF. (3 - Harm, B-R)
3594638
12. For patients with AF, dronedarone should not be administered for maintenance of sinus rhythm to those with NYHA class III and IV HF or patients who have had an episode of decompensated HF in the past 4 weeks, due to the risk of increased early mortality associated with worsening HF. (3 - Harm, B-R)
3594638
* Please see other recommendations on anticoagulation in AF (Section 8.4.4, “Anticoagulation Therapy Before and After Catheter Ablation”), rate control in HF (Section 7, “Rate Control”), and agents for pharmacological cardioversion (Section 7.2, “Specific Pharmacological Agents for Rate Control”) and maintenance of sinus rhythm (Section 8.3.1, “Specific Drug Therapy for Long-Term Maintenance of Sinus Rhythm”).

† Consider the risk of cardioversion and stroke when using amiodarone as a rate-control agent.

10. AF and Specific Patient Groups

10.1. Management of Early Onset AF, Including Genetic Testing

1. In patients with an onset of unexplained AF before the age of 30 years, electrophysiologic study to evaluate and treat reentrant supraventricular tachyarrhythmias with a targeted ablation may be reasonable in view of the high prevalence of reentrant arrhythmias in this group. (2b, B-NR)
3594638
2. In patents with an onset of AF before the age of 45 years without obvious risk factors for AF, referral for genetic counseling, genetic testing for rare pathogenic variants, and surveillance for cardiomyopathy or arrhythmia syndromes may be reasonable. (2b, B-NR)
3594638

10.2. Athletes

1. In athletes who develop AF, catheter ablation with PVI is a reasonable strategy for rhythm control in view of its effectiveness and low risk of detrimental effect on exercise capacity. (2a, B-NR)
3594638

10.3. Management Considerations in Patients With AF and Obesity 

10.4. Anticoagulation Considerations in Patients With Class III Obesity

1. In patients with AF and class III obesity (BMI ≥40 kg/m2 ), DOACs are reasonable to choose over warfarin for stroke risk reduction. (2a, B-NR)
3594638
2. In patients with AF who have undergone bariatric surgery, warfarin may be reasonable to choose over DOACs for stroke risk reduction in view of concerns about DOAC drug absorption. (2b, C-LD)
3594638

10.5. AF and VHD

10.6. Wolff-Parkinson-White (WPW) and Pre-Excitation Syndromes

1. Patients with AF with rapid anterograde conduction (preexcited AF), and hemodynamic instability should be treated with electrical cardioversion. (1, B-NR)

2. For patients with AF with rapid anterograde conduction (pre-excited AF), catheter ablation of accessory pathways (APs) is recommended. (1, B-NR)
3594638
3. In patients with AF with rapid anterograde conduction (preexcited AF) and hemodynamic stability, pharmacological cardioversion with intravenous ibutilide or intravenous procainamide is recommended as an alternative to elective cardioversion. (1, C-LD)
3594638
4. For patients with AF with anterograde accessory pathway conduction (pre-excited AF), pharmacological agents that block AV nodal conduction (verapamil, diltiazem, amiodarone, digoxin, adenosine, or beta blockers) are contraindicated due to risk of precipitating VF or hemodynamic deterioration. (3 - Harm, B-NR)
3594638

10.7. HCM

10.8. Adult Congenital Heart Disease (ACHD)

1. In adults with ACHD and AF, it is recommended to evaluate for and treat precipitating factors and reversible causes of AF, recognizing that residual hemodynamic sequalae may contribute to the occurrence of the arrhythmia. (1, B-NR)
3594638
2. In adults with AF and moderate or complex congenital heart disease, electrophysiological procedures should be performed by operators with expertise in ACHD procedures and in collaboration with an ACHD cardiologist, ideally in specialized centers, when available. (1, C-LD)
3594638
3. In adults with congenital heart disease and symptomatic or hemodynamically significant paroxysmal or persistent AF, an initial strategy of rhythm control is recommended regardless of lesion severity as AF in this population is often poorly tolerated. (1, C-LD)
3594638
4. In symptomatic patients with simple congenital heart disease with AAD-refractory AF, it is reasonable to choose ablation over long-term antiarrhythmic therapies. (2a, B-NR)
3594638
5. In ACHD patients with AF undergoing PVI, it may be reasonable to include an ablative strategy in the right atrium directed at reentrant arrhythmia secondary to atriotomy scars and the CTI. (2b, C-LD)
3594638
6. In adults with AF and moderate or severe forms of congenital heart disease, particularly those with low-flow states such as Fontan circulation, blind-ending cardiac chambers, and cyanosis, it may be reasonable to treat with anticoagulation independent of conventional risk score to reduce risk of thromboembolic events. (2b, C-LD)
3594638

10.9. Prevention and Treatment After Cardiac Surgery

10.9.1. Prevention of AF After Cardiac Surgery

1. In patients undergoing cardiac surgery at high risk for postoperative AF, it is reasonable to administer short-term prophylactic beta blockers or amiodarone to reduce the incidence of postoperative AF. (2a, B-R)
3594638
2. In patients undergoing CABG, aortic valve, or ascending aortic aneurysm operations, it is reasonable to perform concomitant posterior left pericardiotomy to reduce the incidence of postoperative AF. (2a, B-R)
3594638

10.9.2. Treatment of AF After Cardiac Surgery

1. In postoperative cardiac surgery patients,
beta blockers* are recommended to achieve rate control for AF, (1, A)
unless contraindicated or ineffective, in which case
3594638
a nondihydropyridine calcium channel blocker† is recommended. (1, B-R)
3594638
2. In hemodynamically stable cardiac surgery patients with postoperative AF, rate-control (target heart rate <100 bpm) and/or rhythm- control medications are recommended as initial therapy, with the choice of strategy according to patient symptoms, hemodynamic consequences of the arrhythmia, and physician preference. (1, B-R)
3594638
3. In patients who develop poorly tolerated AF after cardiac surgery, DCCV in combination with AAD therapy is recommended, with consideration of imaging to rule out left appendage thrombus before cardioversion in those patients in whom AF has been present >48 hours and who have not been on anticoagulation. (1, B-R)
3594638
4. In patients who develop postoperative AF after cardiac surgery, it is reasonable to administer anticoagulation when deemed safe in regards to surgical bleeding for 60 days after surgery unless complications develop, and to reevaluate the need for longer term anticoagulation at that time. (2a, B-NR)
3594638
5. In patients who develop AF after cardiac surgery and who are treated with rate-control strategy, at 30- to 60-day follow-up it is reasonable to perform rhythm assessment and, if AF does not revert to sinus rhythm spontaneously, consider cardioversion after an adequate duration of anticoagulation. (2a, C-LD)
3594638

10.10. Acute Medical Illness or Surgery (Including AF in Critical Care)

1. Patients with AF identified in the setting of acute medical illness or surgery should be counseled about the significant risk of recurrent AF after the acute illness is resolved. (1, B-NR)
3594638
2. In patients with AF identified in the setting of acute medical illness or surgery, outpatient follow-up for thromboembolic risk stratification and decision-making on OAC initiation or continuation, as well as AF surveillance, can be beneficial given a high risk of AF recurrence. (2a, B-NR)
3594638
3. In patients with AF identified in the setting of critical illness due to sepsis, the benefits of anticoagulation for stroke prevention are uncertain. (2b, B-NR)
3594638

10.11. Hyperthyroidism

1. In patients with hyperthyroidism and AF who have an elevated risk of stroke based on a standard clinical risk score, anticoagulation is recommended until thyroid function has returned to normal and sinus rhythm can be maintained. (1, B-NR)
3594638

10.12. Pulmonary Disease

1. In patients with AF and COPD, it is reasonable to use cardioselective beta blockers for rate control of AF, especially where other indications exist, such as MI and HF. (2a, B-R)
3594638
2. In patients with pulmonary hypertension with pulmonary vascular disease (PHPVD) and AF In patients with pulmonary hypertension with pulmonary vascular disease (PHPVD) and AF or AFL, a rhythm-control strategy is reasonable to improve functional status and potentially prolong survival. (2a, B-NR)
3594638

10.13. Pregnancy

1. In pregnant patients with AF, DCCV is safe to the patient and fetus and should be performed in the same manner as in patients who are not pregnant. (1, B-NR)
3594638
2. In pregnant individuals with structurally normal hearts and hemodynamically stable AF, pharmacological cardioversion with agents with history of safe use in pregnancy, such as intravenous procainamide, may be considered. (2b, C-LD)
3594638
3. In pregnant individuals with AF and without structural heart disease, antiarrhythmic agents with history of safe use in pregnancy, such as flecainide and sotalol, are reasonable for maintenance of sinus rhythm. (2a, C-LD)
3594638
4. In pregnant individuals with persistent AF, rate-control agents with a record of safety in pregnancy, such as beta blockers (eg, propranolol or metoprolol) and digoxin, either alone or in combination with beta blockers, are reasonable as first-line agents. (2a, B-NR)
3594638
5. Pregnant individuals with AF and elevated risk of stroke may be considered for anticoagulation with the recognition that no anticoagulation strategy is completely safe for both the mother and fetus, and an SDM discussion should take place regarding risks to both mother and fetus (see Table 28). (2b, C-LD)
3594638

10.14. Cardio-Oncology and Anticoagulation Considerations

1. In patients with cancer and AF, multidisciplinary communication including cardiology, oncology and other clinicians, and SDM with the patient is recommended to optimize cancer and AF treatment and to reduce the risk of drug-drug interactions, QTc prolongation, proarrhythmia, bleeding, and thromboembolism. (1, C-LD)
3594638
2. In patients who are to be initiated on cancer therapies associated with an increased risk of developing AF, increased vigilance for incident AF and treatment of contributing factors is reasonable to decrease morbidity. (2a, C-LD)
3594638
3. In most patients with AF and cancer (remote history or receiving active cancer treatment), DOACs are reasonable to choose over VKAs for stroke risk reduction. (2a, B-NR)
3594638

10.15. CKD and Kidney Failure

10.16. Anticoagulation Use in Patients With Liver Disease

1. For patients with AF at increased risk of systemic thromboembolism and mild or moderate liver disease (Child-Pugh* class A or B), OAC therapy is reasonable in the absence of clinically significant liver disease-induced coagulopathy or thrombocytopenia. (2a, B-NR)
* Child-Pugh scoring: the severity of liver disease, primarily cirrhosis in patients with diagnosed liver disease. Child-Pugh A (mild): 5–6 points; Child-Pugh B (moderate): 7–9 points; Child-Pugh C (severe): 10–15 points.
The score is based on the 5 variables: encephalopathy (none=1 point, grade 1 and 2=2 points, grade 3 and 4= 3 points); ascites (none=1 point, slight=2 points, moderate=3 points); total bilirubin (<2 mg/mL=1 point, 2–3 mg/mL=2 points, >3 mg/mL=3 points); albumin (>3.5 mg/mL=1 point, 2.8–3.5 mg/mL=2 points, <2.8 mg/mL=3 points); INR (<1.7=1 point, INR 1.7–2.2=2 points, INR >2.2=3 points).
3594638
2. For patients with AF at increased risk of systemic thromboembolism and mild or moderate liver disease (ChildPugh class A or B) who are deemed to be candidates for anticoagulation, it is reasonable to prescribe DOACs (ChildPugh class A: any DOAC; Child-Pugh class B: apixaban, dabigatran, or edoxaban) over warfarin. (2a, B-NR)
3594638
3. For patients with AF and moderate liver disease (Child-Pugh class B) at increased risk of systemic thromboembolism, rivaroxaban is contraindicated due to the potentially increased risk of bleeding. (3 - Harm, C-LD)
