摘要(Abstract)：

目的探索持续性心房颤动线性消融及不同阻滞线与临床复发之间的关系。方法入选2009年5月至2010年7月因持续性房颤首次行导管射频消融术的患者440例。年龄(61±10)岁,男性308例,房颤病程(4.1±5.1)年。在CARTO三维标测系统引导下行环同侧肺静脉前庭电隔离术、心房复杂碎裂电位消融术及必要的线性消融。结果 440例患者均顺利完成射频消融术,142例(32.3%)行线性消融达双向阻滞(线性消融组),298例(67.7%)未行线性消融(非线性消融组)。线性消融组中房顶阻滞线85例(59.9%),二尖瓣峡部线阻滞18例(12.7%),二尖瓣峡部和房顶阻滞线均达双向阻滞39例(27.4%)。术后随访(18.4±5.1)月,消融次数1(1～3)次。线性消融组122例(85.9%)未见复发;非线性消融组225例(75.5%)未见复发(P=0.012)。亚组分析房顶线消融组74例(87.1%)未见复发,二尖瓣峡部线消融组15例(83.3%)未见复发,房顶线和二尖瓣峡部线消融组33例(84.6%)未见复发,两两组间比较差异无统计学意义。结论左心房线性消融并达双向阻滞能进一步提高消融成功率;左心房内不同的消融阻滞线对复发的影响需要更深更广泛的探讨。
