2、心耳封堵术治疗患者全部成功(成功率100%),其中男性6例、女性6例,年龄51~81(66.4±14.5)岁,房颤病史0.5~7(2.78±4.12)年。12例患者CHA2DS2-VASc评分为2~6(4.1±1.9)分。术中TEE测量左心耳开口最大直径为(19.7±2.2)mm;左心耳造影图像测得左心耳开口最大直径为(20.1±2.3)mm;两种方法测量的左心耳开口直径无显著差异(P>0.05)。所用12枚Watchman封堵器直径(25.0±3.2)mm;植入左心耳内后TEE测量封堵器最大直径(20.3±5.8)mm,压缩率为(22.1±3.9)%。6例患者封堵后有少量残余分流,无手
3、术相关并发症。结论:应用Watchman左心耳封堵器进行左心耳封堵是安全、有效的,但需严格把握适应证,遵循严格的操作规范。关键词:心房颤动;左心耳封堵;WatchmanClinicalapplicationofleftatrialappendageocclusionwithWatchmanoccluderYaoQing1,SongZhi-yuan1,※,ShuMao-qin1,GuoYan-li2,ZhongLi1,WangWen-ting2,ShenBin2,LiHua-kang1,CaiHong1,ZhuPing1,LiuFeng1,ChenXia11:DepartmentofCar
