Why the study?
Most studies evaluating AF ablation outcomes included relatively small female cohorts, leaving the impact of sex on procedure safety and outcomes unclear.
Does female sex compared to male sex affect arrhythmia recurrence and procedural complications in patients undergoing catheter ablation for atrial fibrillation?
Population
Patients undergoing AF ablation from January 1, 2014, to March 31, 2021
Comparison
Female vs male patients
Design
Retrospective study
Follow-up
1-year
Key result
Catheter ablation for atrial fibrillation showed similar 1-year arrhythmia recurrence rates between women and men (30% vs 27.7%; p=0.38) and similar procedural complication rates.

Supports equitable AF ablation consideration by sex; leaves open randomized confirmation given observational design.
Cohort
Does female sex compared to male sex affect arrhythmia recurrence and procedural complications in patients undergoing catheter ablation for atrial fibrillation?
Absolute Event Rate: 30% vs 27.7%
p-value: p=.38
Despite women having higher CHA2DS2-VASc scores and trying more antiarrhythmic drugs prior to ablation, there were no significant sex-based differences in 1-year arrhythmia recurrence or procedural complications following catheter ablation for atrial fibrillation.
Yadav et al. (2023) conducted a cohort in Atrial fibrillation. Female sex (Catheter ablation) vs. Male sex was evaluated on Arrhythmia recurrence at 1-year post ablation (p=.38). Catheter ablation for atrial fibrillation showed similar 1-year arrhythmia recurrence rates between women and men (30% vs 27.7%; p=0.38) and similar procedural complication rates.
