摘　　要：为了探讨新型多平面经食管超声心动图（ＭＴＥＥ）测量房间隔缺损（ＡＳＤ）面积的可行性和可靠性，在２３例ＡＳＤ患者中进行了ＭＴＥＥ检查。利用心电图门控于心动周期的Ｐ波顶点、Ｐ－Ｒ段、Ｒ波顶点、Ｊ点、Ｔ波起点、Ｔ波顶点、Ｔ波终点等７个时相，以ＭＴＥＥ技术每隔１０°扫查角度测量ＡＳＤ直径，由此绘出心动周期每一时相的ＡＳＤ图形，并计算其面积，然后与手术测量的ＡＳＤ面积进行比较。结果显示：（１）ＡＳＤ面积在心动周期中呈动态改变；（２）ＭＴＥＥ于Ｐ波顶点测量的ＡＳＤ面积与手术测值相关最佳（ｒ＝０．９２），余心动周期时相ＭＴＥＥ与手术测值亦相关良好（ｒ＝０．８２～０．８８），表明ＭＴＥＥ为ＡＳＤ面积的测量提供了可靠的新方法。Abstract To assess the feasibility and reliability of multiplane transesophageal echocadiography (MTEE) in measuring the area of atriai septal defect (ASD),MTEE was performed in 23 cases with ASD.After the longest diameter of ASD was imaged,the phased array was rotated every 10°through a 0°- 180°arc to obtain a complete recording of 18 diameters of ASD. Using a soft ware program and ECG gating,the area of ASD was recontructed and measured at 7 time points of one cardiac cycle.The result showed that all ASD areas measured at 7 time points by MTEE correlated well with that measured at operation (r= 0. 820. 92) and the best correlation obtained was between ASD area measured at the peak of P wave by MTEE and during operation (r=0. 92). Thus,MTEE offers a new and reliable method for measuring ASD area.
