目的观察双极射频消融术治疗风湿性心脏病慢性房颤的可行性和临床疗效。方法应用Atricure双极射频消融系统,按照迷宫Ⅲ手术线路施行射频消融治疗房颤,同时完成瓣膜置换。结果总共108例患者,术后即转为窦性心率的91例(84.3%),17例(15.8%)术后早期房颤心律或交界区心律。术后死亡2例,106例随访6～24个月,87例(80.6%)为窦性心律,19例(19.4%)为房颤心律或交界区心律。结论双极射频消融改良迷宫术在瓣膜置换的同时治疗房颤可行性好,安全简便,转复率高。
Objective To observe the feasibility and clinical efficacy of bipolar radiofrequency ablation in the treatment of chronic atrial fibrillation with rheumatic heart disease. Methods The Atricure bipolar radiofrequency ablation system was used. Atrial fibrillation was performed according to the labyrinth III surgical radiofrequency catheter ablation procedure. At the same time, the valve replacement was completed. Results A total of 108 patients were converted to sinus heart rate in 91 (84.3%) and postoperative 17 (15.8%) patients with atrial fibrillation or junctional rhythm in the early postoperative period. Postoperative death occurred in 2 patients, 106 patients were followed up for 6-24 months, 87 (80.6%) were sinus rhythm and 19 (19.4%) were atrial fibrillation or junctional rhythm. Conclusion Bipolar radiofrequency ablation improved maze in the valve replacement at the same time the treatment of atrial fibrillation is feasible, safe and easy, high conversion rate.
