射频消融迷宫术治疗心房颤动疗效观察

目的 :探讨直视下射频消融迷宫术治疗心房颤动 (房颤 )的效果。方法 :选取 136例风湿性心脏病并发房颤患者 ,在体外循环心内直视下行射频消融迷宫术 ,同时行瓣膜替换术 ;另选取 18例患者 (包括风湿性心脏病并发房颤 13例 ,先天性心脏病并发房颤 5例 )在体外循环心内直视下行单纯右心房射频消融术 ,同时行瓣膜替换及其他心内畸形矫治。结果 :无手术死亡。射频消融迷宫术组有 112例恢复了窦性心律 ,占 82 .4 %;单纯右心房射频消融术组 11例恢复了窦性心律 ,占 6 1.1%。结论 :射频消融迷宫术治疗房颤成功率高 ,方法简单 ,效果满意 ,危险性小。

Surgical treatment of atrial fibrillation with maze procedure by radiofrequency ablation

Objective:To assess the effect of radiofrequency ablation maze procedure for patients with atrial fibrillation. Method:One handres and thirty six cases of atrial fibrillation with rheumatic valvular heart disease underwent radiofrequency ablation maze procedure, following heart valve replacement; 18 patients with atrial fibrillation including 5 cases of congenital heart disease, 13 cases of rheumatic valvular heart disease, underwent radiofrequency ablation procedure of single right atrium during open heart surgery. Result:No early death occurred. In radiofrequency ablation maze procedure group, 112 cases of 136 cases restored sinus rhythm( 82.4%). In radiofrequenc ablation procedure of single right atrium group, 11 cases of 18 cases restored sinus rhythm( 61.1%).Conclusion:Radiofrequency ablation maze procedure is a simple, safe and effective method to treat atrial fibrillation.
