Nine patients with Ebstein's anomaly of the tricuspid valve were studied by two-dimensional echocardiography, using the standard long and short axis views as well as the apex four chamber view. With this latter view, the displacement of the tricuspid valve into the right ventricle was clearly seen in all nine cases of Ebstein's anomaly and was not noted in a control population. The severity of the tricuspid displacement was assessed by comparing the position of the mitral and tricuspid valves relative to the cardiac apex. The apex four chamber view allowed visualization of the atrioventricular (AV) ring simultaneously with the displaced tricuspid valve, and therefore the size of the "atrialized" right ventricle, true right ventricle and right atrium could be determined. These dimensions compared favorably with angiography.
采用二维超声心动图，利用标准长轴和短轴视图以及心尖四腔视图，对9例三尖瓣埃布斯坦畸形患者进行了研究。通过后者的视图，在所有9例埃布斯坦畸形病例中均清晰可见三尖瓣向右心室的移位，而在对照组中未观察到这种情况。通过比较二尖瓣和三尖瓣相对于心尖的位置来评估三尖瓣移位的严重程度。心尖四腔视图可同时观察到房室环和移位的三尖瓣，因此可以确定“心房化”右心室、真正右心室和右心房的大小。这些尺寸与血管造影结果相比具有优势。
