摘要(Abstract)：

目的评价环肺静脉消融术联合应用环状电极标测对心房颤动(房颤)消融成功率的影响。方法连续入选61例房颤患者,其中男40例,女21例,阵发性房颤50例,慢性房颤11例。在EnsiteNavX三维电解剖标测系统指导下行环肺静脉消融术。应用环状电极标测肺静脉电位,以肺静脉电隔离为消融终点。结果61例均顺利完成手术。环左肺静脉消融使左肺静脉电隔离34例(55.7%),环右肺静脉消融使右肺静脉电隔离35例(57.4%),环左、右肺静脉消融使所有肺静脉电隔离23例(37.7%)。16例阵发性房颤和5例慢性房颤放电时终止房颤,终止房颤部位为左、右上肺静脉外近房顶前、后壁19例,右上肺静脉外后壁中部1例,完成左肺静脉消融时房颤终止1例。平均随访6±2个月,50例阵发性房颤中42例(84.0%)以及11例慢性房颤中5例(45.4%)无房颤发作,总成功率为77%。并发症:少量心包积液1例,经心包穿刺引流后积液消失;左侧血胸1例,经胸腔穿刺引流痊愈。结论EnsiteNavX系统指导下的环肺静脉消融术中联合应用环状电极标测可使房颤消融成功率进一步提高。
