Sex differences in paroxysmal atrial fibrillation catheter ablation: A difference-in-difference propensity score matched analysis.

We did not observe differences in baseline characteristics, arrhythmia recurrences, or procedure-related complications between male and female patients. Sex differences were reflected mainly in the finding that male patients received more cavotricuspid isthmus ablations, and atrial fibrillation duration was the only potential risk factor for recurrence and only for male patients.
