Why the study?
Most prior studies of AF catheter ablation outcomes included relatively small female cohorts, leaving the impact of sex on procedural safety and outcomes unclear.
Does female sex compared to male sex affect arrhythmia recurrence and procedural complications in patients undergoing first catheter ablation for atrial fibrillation?
Population
1346 patients undergoing first catheter ablation for AF
Comparison
Female patients vs male patients
Design
Retrospective study
Follow-up
1-y
Key result
Female sex was associated with similar 1-year arrhythmia recurrence rates (30% vs 27.7%; p=0.38) and procedural complications (3.1% vs 1.8%; p=0.56) compared to male sex after AF catheter ablation.

Supports comparable AF ablation outcomes by sex; extends observational data but leaves causal effects open.
Cohort (n=1,346)
Does female sex compared to male sex affect arrhythmia recurrence and procedural complications in patients undergoing first catheter ablation for atrial fibrillation?
Absolute Event Rate: 30% vs 27.7%
p-value: p=0.38
Despite women being older and having higher CHA2DS2-VASc scores at the time of AF ablation, there are no significant sex-based differences in 1-year arrhythmia recurrence or procedural complications.
Yadav et al. (2023) conducted a cohort in Atrial fibrillation (n=1,346). Female sex vs. Male sex was evaluated on Arrhythmia recurrence at 1-year post ablation (p=0.38). Female sex was associated with similar 1-year arrhythmia recurrence rates (30% vs 27.7%; p=0.38) and procedural complications (3.1% vs 1.8%; p=0.56) compared to male sex after AF catheter ablation.
