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 w
