Abstract：Objective To explore the clinical effect of radiofrequency catheter ablation on patients with heart failure complicated with atrial fibrillation.Methods Twenty-six patients with heart failure complicated with atrial fibrillation who had radiofrequency catheter ablation from March 2012 to June 2015 in Xuanwu Hospital,Capital Medical University were enrolled as observation group,58 patients with atrial fibrillation without congestive heart failure(left ventricular ejection fraction ＜ 45％) were enrolled as control group.The operation success rate and left ventricular function before and after treatment were analyzed.Results The operation success rate had no significant difference between observation group and control group [73.1％ (19/26) vs 79.3％ (46/58)] (P ＞ 0.05).Left atrial diameter and left ventricular end-diastolic diameter in observation group after treatment were significantly lower and left ventricle ejection fraction was significantly higher than those before treatment[(41 ± 5)mm vs (47 ± 5)mm,(49±3)mmvs (58±5)mm,(57 ±6)％ vs (41 ±7)％](P＜0.05).Conclusion Radiofrequency catheter ablation is effective in the treatment of heart failure complicated with atrial fibrillation.
