射频导管消融术治疗心力衰竭合并心房颤动患者的临床效果

Clinical effect of radiofrequency catheter ablation on patients with heart failure complicated with atrial fibrillation

目的 探讨射频导管消融术治疗心力衰竭合并心房颤动患者的临床效果。方法 选择2012年 3月至2015年6月于首都医科大学宣武医院经射频导管消融术治疗的26例心力衰竭合并心房颤动患者（左心室射血分数＜45%）为观察组，并选择同期58例无充血性心力衰竭的心房颤动患者为对照组。比较2组患者手术成功率和治疗前后左心功能。结果 观察组与对照组患者手术成功率比较［73.1%（19/26）比79.3%（46/58）］，差异无统计学意义（P＞0.05）。观察组治疗后左心房内径及左心室舒张末期内径明显小于治疗前，左心室射血分数明显高于治疗前［（41±5）mm比（47±5）mm、（49±3）mm比（58±5）mm、（57±6）%比（41±7）%］（均P＜0.05）。结论 射频导管消融术治疗心力衰竭合并心房颤动患者效果明显。

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）mm vs （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.
