经心房内直视迷宫式射频消融治疗心房颤动─—方法与疗效评价

Clinical study of radiofrequency maze procedure for atrial fibrillation

探讨器质性心脏病合并心房纤颤（房颤），在瓣膜替换及畸型矫治同时心房内直视迷宫式射频消融治疗房颤的可行性．方法：风湿性心脏瓣膜病合并房颤19例，先天性继发孔房缺合并房颤1例，在体外循环心内直视下经心房行迷宫式射频消融，同时行辩膜替换及其他心内畸形矫治．结果：无手术死亡．18例房颤消失，其中窦性心律16例（80％），结性心律1例，心房扑动1例．随访9～29个月，心律稳定，无远期死亡．结论：本方法简捷安全，可以达到治疗房颤的目的，值得进一步研究．

To study the effects of radiofrequency maze procedure on atrial fibrillation(Af). Methods:Twenty patients with Af,including one case of congenital atrial septal defects, 19 of rheumatic valvular disease,underwent continuous line ablation during open heart surgery, valve replacement was made in 19 cases at the same time. The effects and changes were observed. Results: No early death occurred. Af disappeared in 18 cases postoperatively (sinus rhythm in 16 cases,junctional rhythm in one case and atrial flutter in one ). During the follow-up period (9 to 29 months),there was no recurrence. Conclusion: Radiofrequency maze procedure is safe and effective for curing Af,worthy of further research.
