Successful diagnosis and surgical treatment of single ventricle, truncus arteriosus

The association of single ventricle and truncus arteriosus is rare. We present the successful surgical palliation of a patient who echocardiographically and angiographically has a truncus arteriosus type I and single left ventricle. At operation, the main pulmonary artery was dissected off the truncus arteriosus, and a 4-mm polytetrafluoroethylene graft was placed from the ascending aorta to the left pulmonary artery. The patient is currently 13 months old and growing well.
