摘要 目的采用美国Atricure射频消融仪在二尖瓣置换同期进行双极双房外科射频消融,评价手术后疗效。方法2005年12月~2007年6月10例风湿性心脏病二尖瓣病变合并房颤的患者。男6例,女4例。参考Core的MazeⅢ手术路线,设计左右房的消融线路。二尖瓣置换手术同期分别做肺静脉、左心房、右心房的消融。同时血栓清除4例,左房折叠2例。常规置心外膜临时起搏导线。入ICU病房后,即刻静点胺碘酮,拔除气管插管后继续口服胺碘酮片,维持达6个月。结果无死亡病例。10例病人复跳后,心律即转为窦性7例(70.0%),交界性心律3例。出院时10例患者均保持窦性(100.0%)。除1例患者4个月后出现房颤,6个月后仍为房颤,其余9例均保持窦性心律(90.0%)。心功能均良好。结论采用双房双极消融术大大缩短了手术时间。减少了出血等并发症,透壁性好,窦性心律转复率高。
