Characteristics of Patients with Heart Failure Undergoing Catheter Ablation of Atrial Fibrillation.

Objectives Previous studies have shown benefit of catheter ablation of atrial fibrillation in patients with heart failure(HF). This study aims to study characteristics of patients with heart failure undergoing catheter ablation of atrial fibrillation (AF). Methods In this retrospective cohort study, we analyzed 269 consecutive patients with mean age of 61 years who underwent catheter ablation for AF. 64 patients (24%) had known history of Stage C heart failure including both Heart failure with reduced ejection fraction and preserved ejection fraction. We compared baseline characteristics at the time of ablation and procedure outcomes between patients who had known heart failure to those who did not. Results At the time of the procedure, patients with HF had significantly higher body mass index (34.4vs32.3 p=0.0432), CHADS2Vasc score (2.6 vs 1.8 p Conclusion Patients with HF undergoing catheter ablation of AF tend to have more risk factors for recurrence but after adjustment for risk factors, the recurrence rates were similar at 3 months and 1 year.
