Safety and efficacy of catheter ablation in atrial fibrillation patients with left ventricular dysfunction.


ABSTRACT: BACKGROUND:Catheter ablation (CA) for atrial fibrillation (AF) in heart failure (HF) patients reduced the mortality but may increase complications and raise the safety concern. HYPOTHESIS:CA for AF in HF patients may not increase the complications vs medical treatment, and it may reduce hospitalizations and mortality and improve heart function. METHODS:Three groups of AF patients were included in the study: 120 congestive HF for their first CA (AFHF-CA), 150 congestive HF who were undergoing medical therapy (AFHF-Med), and 150 patients with normal left ventricular (LV) ejection fraction (LVEF) (AF-CA). RESULTS:After 30?±?6 months of follow up, 45.8% of patients in the AFHF-CA and 61.3% of patients in the AF-CA groups maintained sinus rhythm (SR) in comparison with 2.7% in AFHF-Med (P?
