摘要 目的比较肺静脉口节段性电隔离(SPVI)和环肺静脉消融(CPVA)两种术式治疗阵发性房颤在方法学、疗效和安全性方面的差异。方法66例阵发性房颤患者30例接受SPVI术,36例接受CPVA术,SPVI组经验性电隔离4条肺静脉。CPVA组采用CARTO电解剖标测系统及双Lasso标测电极技术,分别进行环左、右侧肺静脉线性消融,消融终点为肺静脉电隔离。记录方法学参数:手术时间、射频放电时间、X线曝光时间。术前和术后检查超声心动图、动态心电图和左房及肺静脉螺旋CT三维重建。结果SPVI组手术时间(137±36)min,放电时间(36±10)min,与CPVA组手术时间(208±61)min,放电时间(76±17)min比较差异有显著性(P<0.05),而X线曝光时间(40±13)min,与CPVA组(46±20)min相似(P=0.113)。术后随访(407±150)d,SPVI组和CPVA组手术达到终点率(93%vs86%P=0.343)和治愈率(70%vs75%P=0.650)相似。总的并发症发生率差异无显著性(13%vs8%,P=0.511)。SPVI组3例肺静脉狭窄;CPVA组2例脑梗死,两组各出现1例心包填塞。结论CPVA术治疗阵发性房颤的疗效和安全性与SPVI术相似,而手术时间、放电时间较长。
