Optimal Ablation Strategies for Persistent Atrial Fibrillation With Heart Failure: Three-Year Follow-Up of a Prospective Multicenter Randomized Trial
Abstract
BACKGROUND: Catheter ablation has been shown to improve prognosis in patients with heart failure (HF) and atrial fibrillation (AF); however, the optimal ablation strategy remains undefined. METHODS: In this multicenter, randomized controlled trial, 300 patients with persistent AF and HF, including both HF with reduced ejection fraction (ejection fraction ≤40%) and HF with preserved ejection fraction (ejection fraction >40%, including mid-range ejection fraction [ejection fraction 41% to 50%]), were enrolled and randomized equally to the anatomic-guided ablation, electrogram-guided ablation, and extensive electrogram-anatomic–guided ablation groups, with 100 patients in each group. The coprimary end points were: (1) the composite of cardiovascular death or HF-related hospitalization/urgent visit within 36 months; and (2) maintenance of sinus rhythm at 36 months. Secondary end points included AF burden
