Why the study?
Whether male and female patients with AF differ in recurrence risk after catheter ablation remains controversial, with baseline characteristic differences often confounding findings.
Does male sex compared to female sex affect the risk of recurrence or complications after catheter ablation in patients with paroxysmal atrial fibrillation?
Population
352 matched patients (176 pairs) with drug-refractory paroxysmal AF undergoing first catheter ablation
Comparison
Male vs female patients
Design
Retrospective propensity score-matched study
Follow-up
Up to 3-year

No sex difference in recurrence after matched ablation; leaves open whether unmeasured factors influence outcomes in broader populations.
Does male sex compared to female sex affect the risk of recurrence or complications after catheter ablation in patients with paroxysmal atrial fibrillation?
In a propensity-matched cohort of patients with paroxysmal AF, sex did not significantly affect the risk of arrhythmia recurrence or procedure-related complications after first catheter ablation.
