目的评价风湿性心脏病合并心房颤动(AF)心内直视下双极射频消融治疗的手术效果。方法2006年3月至2008年12月风湿性心脏病患者20例接受瓣膜置换术加双极射频消融改良迷宫Ⅲ型手术治疗。结果术后窦性心律14例(70%),AF心律3例(15%),结性和起搏心律3例(15%)。平均随访18.2个月,84.2%(16/19)维持窦性心律,10.5%(2/19)为AF心律。结论风湿性心脏病合并AF术中双极射频消融治疗,术后长期窦性心律维持率较高,双极射频消融手术作为心脏手术的附加手术具有安全、省时、治疗AF效果好等优点。
Objective To evaluate the surgical effect of bipolar radiofrequency ablation under rheumatic heart disease with atrial fibrillation (AF). Methods From March 2006 to December 2008, 20 patients with rheumatic heart disease underwent valve replacement and bipolar radiofrequency ablation and modified maze type Ⅲ. Results Postoperative sinus rhythm was found in 14 cases (70%), AF rhythm in 3 cases (15%), nodularity and pacemaker rhythm in 3 cases (15%). The mean follow-up was 18.2 months. 84.2% (16/19) maintained sinus rhythm and 10.5% (2/19) were AF rhythm. Conclusions Bipolar radiofrequency catheter ablation in patients with rheumatic heart disease complicated with AF has long-term maintenance of sinus rhythm after surgery. Bipolar radiofrequency catheter ablation is safe, time-saving and effective in treating AF.
