摘要(Abstract)：

目的比较环肺静脉电极指引下的肺静脉前庭导管消融与单导管技术隔离肺静脉前庭对阵发性心房颤动(房颤)治疗方法学和疗效的差异。方法 2010年9月至2013年9月共有135例阵发性房颤患者在北京同仁医院接受导管消融治疗,分为环肺电极组54例和单导管消融组81例,行三维标测系统(CARTO)下房颤导管消融。行双侧肺静脉前庭隔离后,比较两组的安全性、时效性和临床效果。结果环肺电极组肺静脉前庭隔离52例(96.3%),单导管消融组78例(96.3%),两组隔离率比较,差异无统计学意义(P>0.05)。在手术操作时间上,单导管消融组明显快于环肺电极组[(76±41)min比(101±32)min,P<0.05]。单导管消融组X线曝光时间明显少于环肺电极组[(12±6.1)min比(24±6.5)min,P<0.05]。随访8个月,不使用抗心律失常药物成功维持窦性心律的患者,环肺电极组43例(79.6%),单导管消融组67例(82.7%),两组差异无统计学意义(P>0.05);环肺电极组有2例肺静脉缩窄的并发症。结论对于阵发性房颤的消融,单导管消融优于环肺静脉电极指引下导管消融,应用单导管技术定位缝隙实现肺静脉前庭的完全隔离安全有效。
