Arrhythmias & electrophysiology

Sex-specific outcomes after catheter ablation for persistent atrial fibrillation (AF)

Heart RhythmPublished Secondary analysis of the CAPLA randomised trial

Corrected 23 Oct 2026: Measure wording clarified; no values changed.

Authors' conclusion

Women undergoing CA for PsAF report more significant symptoms and poorer quality of life at baseline than men. Despite higher arrhythmia recurrence and repeat procedures in women, the AF burden was comparably low, resulting in significant improvements in quality of life and psychological well-being after CA in both sexes.
