Description of the history, the clinical findings, and the autoptic results in a 5-days-old newborn child with a truncus arteriosus (Type I) and an interrupted aortic arch (Type B). Perfusion of the distal aortic arch by a wide open Ductus arteriosus. Additional anomalies: Atrial septal defect with partial anomalous pulmonary venous drainage of the right lung into the right atrium. Persistant left superior vena cava which leads to the left atrium. Hypoplasia and dysplasia of the left kidney. A tear caused by friction in the left sensorium with intra-and subdural bleeding. Discussion of the clinical, electrocardiographic, radiologic, angiocardiographic and pathologic-anatomical peculiarities of the persistent Truncus arteriosus and of the interrupted aortic arch connected with both defects.
