Drastic cardiac reverse remodeling following catheter ablation in patients with atrial fibrillation and heart failure

Abstract

In the management of atrial fibrillation in patients with heart failure, rate control is recommended, whereas the implication of rhythm control remains controversial. We experienced a 65-year-old man who had compensated heart failure due to hypertensive heart disease and atrial fibrillation with well-controlled heart rate (<100 bpm). At three months following the catheter ablation procedure, the left ventricular ejection fraction improved from 40% up to 65%. The implication of rhythm control using catheter ablation in improving cardiac reverse remodeling should be validated in large-scale clinical studies.
