The Association Between Significant Mitral Regurgitation and Atrial Fibrillation Recurrence Post-Ablation.

ABSTRACT: Background: Atrial fibrillation (AF) is a common tachyarrhythmia associated with increased morbidity. AF frequently occurs alongside mitral regurgitation (MR). Although the impact of MR severity on AF is well proven, its effect on AF recurrence post-ablation is unclear and was the focus of our study. Methods: Retrospective single-center cohort of patients who underwent AF catheter ablation from 2014 to 2024. Pre-procedural transthoracic echocardiograms evaluated pre-ablation baseline MR severity. Patients with 'significant' MR (defined as moderate-severe or severe MR) were compared to those with 'non-significant' MR. Univariate Kaplan-Meier (KM) survival analysis, multivariable Cox proportional hazards models, and inverse probability treatment weighting (IPTW) method were app
