Catheter and Surgical Ablation of Atrial Fibrillation

Publication Date: April 8, 2024

Key Points

Key Points

  • Catheter and surgical ablation of atrial fibrillation (AF) are well established and important treatment options for patients with atrial fibrillation in whom a rhythm control strategy is chosen.
  • A decision to perform catheter or surgical ablation of AF should be made after a careful consideration of the efficacy, risks, and alternatives to undergoing the ablation procedure. Patient preferences and values are important consideration. This document provides indications for both catheter and surgical AF ablation.
  • The primary indication for performance of AF ablation is the presence of symptoms associated with atrial fibrillation. AF ablation is generally considered after at least one antiarrhythmic medication has been tried and proven to be ineffective or poorly tolerated.
  • A desire to stop anticoagulation is not an appropriate indication for AF ablation. For most patients with AF who have a high stroke risk profile, anticoagulation should be continued following their ablation procedure.
  • Catheter ablation of AF is associated with a risk of complications including development of a stroke or transient ischemic attack. Careful attention to anticoagulation prior to, during, and following the ablation procedure minimizes these risks.
  • Multiple tools and strategies are available to perform both catheter and surgical ablation of AF. This document provides a detailed review of each of the available options and recommendations are made.
  • There is considerable effort focused on developing new tools and techniques for AF ablation. This document contained recommendations concerning the performance of future clinical trials.
