经胸和多平面经食管超声心动图诊断房间隔缺损

在５３例各种类型房间隔缺损（ＡＳＤ）患者中，进行了经胸（ＴＴＥ）和多平面经食管（ＭＴＥＥ）超声心动图检查。结果显示；与手术诊断相比，ＴＴＥ和ＭＴＥＥ的诊断符合率分别为６８．４％和１００％。对于小型继发孔型、静脉窦型和多发性ＡＳＤ以及合并的部分肺静脉畸形引流的检出率，ＭＴＥＥ显著高于ＴＴＥ。ＴＴＥ和ＭＴＥＥ与手术测量的ＡＳＤ最大直径的相关系数分别为０．７５和０．９５，表明ＭＴＥＥ为定性，定位和定量诊断ＡＳＤ提供了高度可靠的新技术。

A Comparative Study of Transthoracic and Multiplane Transesophageal Echocardiography in the Quanlitative and Quantitative Diagnosis of Atrial Septal Defect

To Compare the accuracy of transthoracic echocardiography (TTE) and multiplane transesophageal echocardiography (MTEE) in the qualitative and quantitative diagnos is of atrial septal defect(ASD),TTE and MTEE were performed in 53 cases with various anatomical types of ASD. The result showed that the diagnostic accuracy of TTE and MTEE was 68. 4% and 100% respectively,when compared with surgical findings. MTEE was highly superior to TTE in detecting small ostium secundum ASD, sinus venous ASD and multiple ASD as well as associated partial anomalous pulmonary venous drainage. The maximal diameter of ASD measured by TEE correlated moderately with that measured at operation, while the same parameter measured by MTEE correlated well with that measured at operation(r= 0. 75 and 0. 95 respectively, P<0. 001).It is conclueded that MTEE offers a new and accurate technique for qualitative and quantitative diagnosis of ASD.
