The plain roentgenographic and angiocardiographic features of 15 patients with Ebstein's anomaly of the tricuspid valve were reviewed. Of note on the plain roentgenogram was the fact that the "posterior bulge" seen on the lateral view was demonstrated to be due to either a markedly enlarged right atrium or the posterior displacement of normal left heart structures. The angiocardiographic features described in the literature were reviewed. Two main features seen were the "sail-like" appearance of the anterior leaflet of the tricuspid valve, which sometimes produces a tumor like picture, and the 2 notches seen when the ventricle contracts. One notch corresponds to the true tricuspid annulus. The other represents the site of attachment of the displaced tricuspid valve. The previously undescribed features were noted: (a) all three leaflets could sometimes be identified; (b) fenestrations in the anterior leaflet were demonstrated in 5cases; and (c) the sinus portion of the ventricle was sometimes filled in a retrograde fashion from the infundibular chamber.
回顾了15例三尖瓣埃布斯坦畸形患者的普通X线和心血管造影特征。普通X线片上值得注意的是，侧位片上所见的“后凸”被证明是由于右心房明显扩大或正常左心结构向后移位所致。对文献中描述的心血管造影特征进行了回顾。主要看到两个特征：三尖瓣前叶的“帆样”外观，有时会产生肿瘤样图像；心室收缩时可见两个切迹。一个切迹对应真正的三尖瓣环。另一个代表移位的三尖瓣附着部位。还注意到了以前未描述的特征：(a)有时可以识别出所有三个瓣叶；(b)5例患者的前叶有开窗；(c)心室的窦部有时会从漏斗部逆行充盈。
