مستخلص: | Objectives: This study sought to determine the long-term outcomes of restoring sinus rhythm with catheter ablation (CA). Background(s): 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. Method(s): Patients enrolled in the CAMERA-MRI study were followed for 4 years with echocardiogram and cardiac magnetic resonance. CA involved pulmonary vein isolation and posterior left atrial wall isolation in 94%. Patients crossed over to CA after 6-month study duration. Arrhythmia burden was determined with implanted cardiac monitors or cardiac devices. Result(s): Sixty-six patients (age 62 +/- 10 years, atrial fibrillation duration of 22 +/- 16 months, and LVEF 33 +/- 9%) were randomized 1:1 to CA versus MRC. Eighteen of 33 patients crossed over from MRC group to CA group. At 4.0 +/- 0.9 years, atrial fibrillation recurred in 27 patients (57%) in the CA group with a mean burden of 10.6 +/- 21.2% after 1.4 +/- 0.6 procedures. There was an absolute increase in LVEF with CA of 16.4 +/- 13.3% compared with 8.6 +/- 7.6% in MRC (p = 0.001). In the CA group, the absence of ventricular late gadolinium enhancement was associated with a greater improvement in absolute LVEF (19 +/- 13% vs. 10 +/- 11% in the late gadolinium enhancement-positive group; p = 0.04) and LVEF normalization in 19 patients (58%) versus 4 patients (18%) in the late gadolinium enhancement-positive group (p = 0.008) at 4.0 +/- 0.9 years follow-up. Conclusion(s): CA is superior to MRC in improving LVEF in the long term in patients with atrial fibrillation and systolic heart failure. The greatest recov |
