Seven patients with Ebstein's anomaly were studied by two-dimensional echocardiography, with and without stop-action technique, and by standard echocardiography. Sagittal two-dimensional echocardiograms visualized a small functional right ventricle and a large atrialized right ventricle. These two parts of the chamber were separated by the anterior tricuspid leaflet and its chordae tendineae. The echocardiograms corresponded to the findings of the right ventriculogram. In horizontal two-dimensional echocardiograms a huge anterior tricuspid leaflet, atrialized right ventricle, and a displaced septal tricuspid leaflet, intervening between the functional right ventricle and the sinus portion of the functional right ventricle, were visualized. The origin of the septal tricuspid leaflet was clearly shown to be abnormal in five cases. The left ventricle was small with distinct clockwise rotation of the interventricular septum. Two-dimensional echocardiography provided information useful in evaluation of the functions of the right ventricle and the tricuspid valve and determination of what surgical procedure to follow.
对7例埃布斯坦畸形患者进行了二维超声心动图检查，包括使用和不使用定格技术的检查以及标准超声心动图检查。矢状面二维超声心动图显示出一个小的功能性右心室和一个大的房化右心室。心室的这两个部分由三尖瓣前叶及其腱索分隔。超声心动图结果与右心室造影的结果相符。在水平面二维超声心动图中，可以看到巨大的三尖瓣前叶、房化右心室以及位于功能性右心室与功能性右心室窦部之间的移位的三尖瓣隔叶。在5例病例中，三尖瓣隔叶的起源明显异常。左心室较小，室间隔有明显的顺时针旋转。二维超声心动图为评估右心室和三尖瓣的功能以及确定后续手术方案提供了有用的信息。
