摘　　要：５３例风心病二尖瓣狭窄（ＭＳ）患者中，２２例合并左房血栓（ＬＡＴ）和／或左心耳血栓（ＬＡＡＴ）都进行经胸二维超声心动图（ＴＴＥ）和经食管二维超声心动图检查（ＴＥＥ）并经外科手术证实。ＴＴＥ和ＴＥＥ诊断ＬＡＴ和／或ＬＡＡＴ的诊断正确指数、敏感性、特异性分别为５９．８８％、７１．６％、８９．３％和８６．６％、９０％、９６．７％。前两项参数两种方法的差异有非常显著意义（ｔ＝６．２５～１１．３，Ｐ＜０．００１），提示ＴＥＥ优于ＴＴＥ，特别对ＬＡＡＴ的诊断。研究结果表明：ＴＥＥ是具有极高临床价值的诊断方法。文中还讨论了ＴＥＥ误诊的原因。Among 53 cases with rheumatic mitral stenosis,22 cases had left atrlal thrombus(LAT)and/or left atrial appendage thrombus(LAAT).They were both examined by transthoracic echocardiography(TTE)and tranxesophageal echocardiography(TEE)and confirmed by surgery.The accuracy index,sensitivity rate of LAT and LAAT diagnosed by TTE and TEE were 59.88%,71.6%,89.3%and 8.6,90%.96.7% respectively.In comparison TEE with TTE,the accuracy index and sensitivity had statistical significance(t=6.25-1.3,P<0.001).These reults indicated TEE was better than TTE in detecting LAT and/or LAAT.
