Aortopulmonary window with aortic origin of the right pulmonary artery.

Cross-sectional Doppler echocardiographic diagnosis of an aortopulmonary window with type B interrupted aortic arch, and anomalous origin of the right pulmonary artery from the ascending aorta was made in a 15-day-old neonate. This is the first known reported case of surgical repair for this rare association based on prospective echocardiographic diagnosis alone.
