Figure 2 Transthoracic echocardiogram of truncus arteriosus type I. Two-dimensional and color Doppler imaging demonstrating a large perimembranous VSD with an overriding truncal valve. The color Doppler panel highlights bidirectional shunting across the VSD, consistent with severe right ventricular pressure overload. VSD – ventricular septal defect; LV – left ventricle; TV – truncal valve.
