摘要 心房颤动(房颤)是临床上常见的心律失常,据统计,人群中房颤总发生率为0.4%~2.0%,且随着年龄的增加而逐渐上升,年龄每增加10岁,房颤的发生率增加1.4倍[1]。非风湿性房颤导致的脑动脉栓塞病例中,90%以上的栓子来源于左心耳(left atrial appendage,LAA)[2]。19世纪30年代起心脏外科医生在手术时封闭左心耳以预防房颤患者栓塞的发生[3]。但是对于仅仅是切除或封闭左心耳来说外科手术创伤较大,且约36%的外科手术不能完全封闭左心耳[4]。经皮左心耳封堵术(percutaneous left atrial appendage trancatheter occlusion,PLAATO)是使用特制的封堵器使左心耳闭塞,从而达到预防房颤血栓栓塞的目的,这是近十年来发展起来的一种微创非手术性新疗法[5]。
