Summary

We reviewed the echocardiographic features of 16 children with prominent Eustachian valves, six of whom had associated pathology of the right heart, while eight had other anomalies, primarily atrial and ventricular septal defects. The hearts of two patients were structurally normal. Prolapse of the membrane through the orifice of the tricuspid valve or through the atrial septum was present in seven patients, two of whom were symptomatic. One presented with severe cyanosis which resolved after surgical removal on the basis of the echocardiographic findings. The other presented with atrial arrhythmias which did not improve with removal. The size or behavior of the membrane, including prolapse, did not correlate with either age or presence of pathology of the right heart. The echocardiographic appearance of prominent Eustachian valves is variable. Rarely, when prominent, the valves can cause symptoms associated with obstruction to the right heart, particularly cyanosis or an arrhythmia.
