The (M-mode) echocardiographic patterns of three patients with congenital aneurysm of the right sinus of Valsalva are reported. In two patients the aneurysm ruptured into the right ventricular cavity. In the third case, in which the lesion was associated with coarctation of the aorta, no communication was shown between the aorta and other cardiac chambers. The characteristic echocardiographic features of the right coronary sinus aneurysm (either with or without rupture in the right ventricular cavity) consist of: 1) The presence of echoes (referable to the right aortic cusp pattern of motion) encroaching the right ventricular outflow tract. 2) The presence of the same box-shaped echoes at a low level of the left ventricular cavity, which seem to "cross" the septum (from the left to the right ventricular outflow tract). These images would reflect the "prolapse" of the affected cusp. Other common, but non-specific echocardiographic features of the lesion are: an indistinct contour of the anterior wall of the aortic root (probably due to dilatation of the right coronary sinus) and systolic indentations on the right anterior aortic cusp echoes.
本文报告了3例瓦氏窦右窦先天性动脉瘤患者的（M型）超声心动图表现。其中2例患者的动脉瘤破裂进入右心室腔。在第3例中，病变与主动脉缩窄相关，未显示主动脉与其他心腔之间存在交通。右冠状动脉窦瘤（无论是否破裂进入右心室腔）的特征性超声心动图表现包括：1）存在侵入右心室流出道的回声（与右主动脉瓣叶的运动模式相关）。2）在左心室腔较低水平存在同样的盒状回声，似乎“穿过”室间隔（从左心室到右心室流出道）。这些图像反映了受累瓣叶的“脱垂”。该病变其他常见但非特异性的超声心动图表现为：主动脉根部前壁轮廓不清（可能由于右冠状动脉窦扩张）以及右前主动脉瓣叶回声上的收缩期切迹。
