The 2025 SCAI Scientific Sessions wrapped up over the weekend. The annual conference, hosted by the Society for Cardiovascular Angiography & Interventions, saw interventional cardiology experts from around the world meet to discuss the latest insight, clinical guidance, and more.
This year’s SCAI Scientific Sessions featured over 380 abstracts and gathered more than 1,900 attendees. The conference ran through the weekend of May 1 through May 3 and featured hundreds of posters showcasing the latest in acute coronary syndromes, structural heart disease, aortic valve interventions, and more.
The following are just a few of the many posters presented at SCAI 2025 Scientific Sessions.
Dominant Hands, Dominant Arteries: Unraveling the Connection Between Handedness and Coronary Dominance in Veterans
Description: With a predominant proportion of the population being right-handed, and left coronary artery dominance being linked with poorer coronary disease outcomes, the study examined the potential link between hand dominance and coronary dominance.
Result: No major correlation or meaningful association between hand and coronary artery dominance was observed. Because the study used veterans, other subpopulations could be studied to explore additional possible correlations.
Comparison of 30-Day Clinical Outcomes Between Coronary Artery Bypass Grafting (CABG) and Percutaneous Coronary Intervention (PCI) in ST-Elevation Myocardial Infarction with Culprit Left Main Stem Coronary Artery: A Real-World Analysis
Description: A population of 2,438 patients with STEMI and left-main stem as the culprit vessel who also underwent PCI or CABG procedures were identified to compare clinical outcomes between the two procedures.
Result: The patients who underwent CABG experienced fewer cardiovascular complications and lower 30-day mortality, marking the procedure as likely preferable when feasible.
Impact of Rhabdomyolysis on Clinical Outcomes in Patients with Acute Myocardial Infarction
Description: Rhabdomyolysis presents a challenge to clinicians due to its co-occurrence in patients with myocardial infarction.
Result: Of the 582,249 adult patients observed with myocardial infarction from the 2021 National Inpatient Sample database, it was observed that .67% of those patients had rhabdomyolysis as well. In addition to an increase in in-hospital mortality, rhabdomyolysis was also associated with longer hospital stays and increased odds of hemodialysis, cardiogenic shock, acute kidney injury, and cerebrovascular accident.
Sex Differences in Demographics, Comorbidities, and In-Hospital Outcomes After Transcatheter Atrial Septal Defect Closure: A National Analysis (2018-2021)
Description: Transcatheter atrial septal defect (ASD) closure assessment of outcomes between male and female patients may yield insights into considerations for gender differences.
Result: Females were observed to have a lower adjusted odds ratio for acute kidney injury and mortality. However, females had a higher odds ratio for vascular complications.

Effect of Diabetes Mellitus on In-hospital Outcomes Following ASD Transcatheter Closure
Description: The study focused on the impact of diabetes mellitus (DM) on patients who had atrial septal defect (ASD) transcatheter closure.
Result: Compared with the control group, patients who underwent ASD transcatheter closure and had DM experienced higher mortality. DM is a significant predictor of mortality in patients who underwent ASD transcatheter closure, but no significant difference was noted otherwise.
Outcomes of ST-Elevation Myocardial Infarction Among Diabetic Patients on Tirzepatide Versus GLP-1 Receptor Agonists: A Retrospective Study Using Real World Data
Description: There is limited data on tirzepatide (dual GLP-1/GIP receptor agonist). GLP-1 receptor agonists are recognized to reduce cardiovascular mortality in patients with type 2 diabetes mellitus. The study observed STEMI outcomes among patients with type 2 diabetes mellitus who were treated with tirzepatide compared to patients treated with GLP-1 receptor agonists.
Result: Tirzepatide was observed to have a significantly lower risk of mortality following STEMI.
