[摘要] 目的 以射频术改良Cox手术，克服Cox手术操作复杂、术后出血及心包填塞等潜在危险。方法 2005年1月～2006年1月，我院对37例风湿性二尖瓣病合并房颤的患者实施瓣膜置换术，同时采用Maze-Ⅲ径路，以直视线性消融结合局灶性消融治疗房颤。结果 以患者出院时的心电图情况为依据，33例转复为窦性心律，占89%，4例房颤未纠正，全组无死亡、无心包填塞等并发症。结论 此改良迷宫手术操作相对简单、结果满意、并发症较少、便于临床推广，对于瓣膜病合并房颤，需要行人工心脏瓣膜置换术的患者，此种方式是个很好的选择。

    [Abstract] Objective To overcome complex technique and possible massive bleeding after operation by modifying Cox maze procedure.Methods We treated 37 cases of atrial fibrillation with rheumatic heart disease using radiofrequency ablation maze procedure as valve discharged.Results 33 cases of 37 cases resumed sinus rhythm (88%),4 patients remained AF.Conclusion Radiofrequency maze procedure is a simple,safe and effective method and is easy to be adopted in common use.Therefore,the modified maze procedure should be considered for patients with rheumatic valvular disease with chronic atrial fibrillation undergoing mitral valve operations. ......
