Prognostic benefit of catheter ablation of atrial fibrillation in heart failure: An updated meta-analysis of randomized controlled trials.

Our meta-analysis demonstrates AF ablation is superior to 'other care' in improving mortality, HF hospitalization, LVEF and quality of life in patients with HF. However, the highly selected study populations in included RCTs and effect modification mediated by etiology of HF suggests these benefits do not uniformly apply across the HF population.
