改良线路心房直视迷宫式射频消融治疗心房颤动

目的：探讨风湿性心脏病合并心房颤动（房颤）病人，在瓣膜置换同时采用改良线路经心房直视迷品式射频消融治疗房颤的可行性及疗效。方法：66例风湿性心脏病二尖瓣病变合并房颤病人，在体外循环心内直视下经心房行迷宫式射频消融，同时行二尖瓣置换术，结果：无手术死亡，57例房颤消失，其中术后窦性心律54例（81．8％），结性心律1例（1．5％），心房扑动2例（3％），9例（13．6％）仍为房颤，随访2－60个月，总随访率89．6％，窦性心律稳定，无远期死亡，结论：经心房内视改良线路迷宫式射频消融治疗房颤，方法简捷，安全有效，远期疗效稳定，值得进一步研究,推广。

Clinical study of radiofrequency maze procedure in modified pathway for curing atrial fibrillation and follow-up result

Objective: To evaluate the effects of radiofrequency maze procedure in modified pathway for curing atrial fibrillation (Af). Methods: 66 patients of rhematic heart disease associated with Af underwent continuous radiofrequency ablation during open heart operation. The valve replacement was performed at the same time. Results: There was no operative death. Af disappeared in 57 cases postoperatively (sinus rhythm in 54 cases, junctional rhythm in 1, and atrial flutter in 2). Af still existed in 9 cases (13 6%). During the follow up period (2 to 60 months), there were no recurrence and late death. Conclusion: Radiofrequency ablation maze procedure is safe, simple and effective for curing Af.
