Clinical Outcomes of Catheter Ablation versus Transcatheter Edge-to-Edge Repair as the Initial Intervention Strategy in Patients with Atrial Fibrillation and Functional Mitral Regurgitation.
BACKGROUND Atrial fibrillation (AF) and functional mitral regurgitation (FMR) frequently coexist and are linked through shared mechanisms of atrial and ventricular remodeling. Both catheter ablation and transcatheter edge-to-edge mitral valve repair (M-TEER) improve clinical status, yet the optimal sequence of these in...
