摘要(Abstract)：

目的 探讨持续性心房颤动（房颤）患者在射频消融的基础上加行经皮左心耳封堵术的有效性和安全性及对消融复发率的影响。方法 纳入2015年4月至2018年10月在河北医科大学第二医院心内科行射频消融及Watchman左心耳封堵一站式手术的非瓣膜性持续性房颤患者66例（一站式组），以及同期在本中心接受射频消融的持续性房颤患者174例（射频消融组）。经1︰1倾向性评分匹配后，两组各有65例患者纳入分析。比较两组临床特征、围术期与随访期间主要不良事件发生率以及房颤复发率。结果 两组患者临床基线资料比较，差异均无统计学意义（均P>0.05）。两组均成功进行了环肺静脉电隔离，术后均为窦性心律。一站式组患者均成功置入Watchman封堵器，在3个月的经食管超声心动图随访中1例患者出现器械相关血栓。在12个月的随访中，一站式组出现2例出血事件，射频消融组1例患者在房颤消融后3个月出现脑出血。两组术后不良事件的发生率比较，差异均无统计学意义（均P>0.05）。Kaplan-Meier生存曲线显示，在3个月的空白期内，两组的早期事件发生率比较，差异无统计学意义（P=0.224）；在12个月的随访中，一站式组房颤复发率与射频消融组相比，差异无统计学意义（27.7%比24.6%,P=0.984）。多因素Cox回归分析显示，在空白期（HR1.44,95%CI0.72～2.86,P=0.300）或长期随访期（HR0.95,95%CI0.47～1.90,P=0.876）均没有确定不同术式与早期事件及房颤复发之间的关联。结论 射频消融及Watchman左心耳封堵一站式手术治疗房颤是安全有效的，但在射频消融的基础上，加行左心耳封堵对持续性房颤的消融复发率并无影响。
