Aortopulmonary Window with Pulmonary Atresia in a Calf

Abstract

Aortopulmonary window was observed in a five-day-old male Horstein calf. The aortic and pulmonary valves were completely separated by the conus septum, and the distal part of the pulmonary trunk was atretic and disappeared. The heart was associated with atrial and ventricular septal defects, double outlet right ventricle and single coronary artery.
