Abstract

OBJECTIVES: This study sought to determine the long-term outcomes of restoring sinus rhythm with catheter ablation (CA). BACKGROUND: The CAMERA-MRI (Catheter Ablation Versus Medical Rate Control in Atrial Fibrillation and Heart Failure-An MRI-Guided Multicenter Randomized Controlled Trial) study demonstrated that restoration of sinus rhythm with CA significantly improved left ventricular ejection fraction (LVEF) compared with medical rate control (MRC) at 6 months in persistent atrial fibrillation and otherwise unexplained systolic heart failure. However, the long-term outcomes have not been reported. METHODS: Patients enrolled in the CAMERA-MRI study were followed for 4 years with echocardi..
