Previous studies on small numbers of patients have indicated a high incidence of increased right ventricular dimension and abnormal ventricular septal motion in patients with atrial septal defect. However, recent evidence suggests that septal motion may be normal in as many as 46% of patients with atrial septal defect when observed at proper levels. We have analyzed the echocardiograms of 120 patients with sinus venosus or secundum atrial septal defect in an attempt to define sensitivity of the foregoing two echocardiographic abnormalities. Right ventricular dimension index was increased in 98% of patients. When both sides of the ventricular septum were analyzed, abnormal ventricular septal motion was observed in 87% of patients. It is important to observe both right and left septal echoes at all levels. Other measurements and observations were made when possible and are included in the study.
