Twenty nine patients with isolated perimembranous ventricular septal defects were investigated by M mode, cross sectional, and pulsed Doppler echocardiography. Tricuspid valve anomalies were present in all six patients with a left ventricular-right atrial shunt but in only six (26%) of 23 patients who had interventricular shunts only. Systolic flutter of the tricuspid valve was shown in five (83%) of the six patients with a ventriculoatrial shunt but not in the other patients. Systolic turbulence in both the right ventricle and right atrium was detected by Doppler echocardiography only in patients with ventriculoatrial shunting. A perimembranous ventricular septal defect with left ventricular to right atrial shunt can be diagnosed by its combined M mode, cross sectional, and pulsed Doppler echocardiographic features.

对29例孤立性膜周部室间隔缺损患者进行了M型、横断面和脉冲多普勒超声心动图检查。在所有6例存在左心室-右心房分流的患者中均发现三尖瓣异常，但在仅存在心室间分流的23例患者中，只有6例（26%）出现三尖瓣异常。6例存在心室-心房分流的患者中有5例（83%）出现三尖瓣收缩期扑动，而其他患者未出现。仅在存在心室-心房分流的患者中，通过多普勒超声心动图检测到右心室和右心房的收缩期湍流。具有左心室至右心房分流的膜周部室间隔缺损可通过其M型、横断面和脉冲多普勒超声心动图的综合特征进行诊断。
