Impact of Residual Functional Mitral Regurgitation After Atrial Fibrillation Ablation on Clinical Outcomes in Patients With Left Ventricular Systolic Dysfunction

Functional mitral regurgitation (FMR) negatively impacts the prognosis in patients with atrial fibrillation (AF) and reduced left ventricular (LV) ejection fraction (LVEF). Although structural reverse remodeling after AF ablation can reduce FMR severity, the prognostic impact of FMR and its evolutio...

Zusammenfassung:	Functional mitral regurgitation (FMR) negatively impacts the prognosis in patients with atrial fibrillation (AF) and reduced left ventricular (LV) ejection fraction (LVEF). Although structural reverse remodeling after AF ablation can reduce FMR severity, the prognostic impact of FMR and its evolution remain unclear. Of 491 patients with baseline LVEF
