4C 2021 | 储慧民教授:左心耳封堵极简术式的探索及拓展
储慧民 杜先锋 宁波市第一医院 心律失常诊疗中心



X轴,ICE探头置于左上肺静脉(LSPV),自后向前扫描LAA及封堵器(图2左列);
Z轴,ICE探头置于二尖瓣环口部(MAO),自下向上扫描LAA及封堵器(图2右列)。

图2. ICE指导下的LAAC极简术式。左、中、右三列分别为X轴、Y轴、Z轴方向ICE对LAA及Watchman封堵器进行扫描。上排为ICE图像,下排为ICE探头所处的三个关键解剖学位置,分别为LSPV、RPVO、MAO,黄色虚线圈为ICE探头。LAAC,左心耳封堵;ICE,心腔内超声心动图;LSPV,左上肺静脉;RPVO,右肺静脉口部;MAO,二尖瓣环口部;WM,Watchman封堵器;LAO,左前斜位;RAO,右前斜位。
