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 patients with rheumatic mitral stenosis (MS), 22 patients with left atrial thrombus (LAT) and / or left atrial appendage thrombus (LAAT) underwent transthoracic two-dimensional echocardiography (TTE) and transesophageal two- Cardiac examination (TEE) and confirmed by surgery. The diagnostic correct index, sensitivity and specificity of TTE and TEE in diagnosing LAT and / or LAAT were 59.88%, 71.6%, 89.3% and 86.6%, 90% and 96.7% respectively. The first two parameters of the difference between the two methods have very significant (t = 6.25 ~ 11.3, P <0.001), suggesting that TEE is superior to TTE, especially for the diagnosis of LAAT. The results show that: TEE is a diagnostic method with high clinical value. The article also discusses the reasons for misdiagnosis of TEE.
