OUTCOMES AFTER CATHETER ABLATION OF ATRIAL FIBRILLATION IN PATIENTS WITH HEART FAILURE WITH PRESERVED EJECTION FRACTION: INSIGHTS FROM THE UC SAN DIEGO AF ABLATION REGISTRY

Catheter ablation improves clinical outcomes in symptomatic atrial fibrillation (AF) patients with heart failure (HF) with reduced ejection fraction (HFrEF). However, the role of catheter ablation in HF patients with a preserved ejection fraction (HFpEF) is less clear. We performed a retrospective
