Overview
Aortopulmonary window or Aorticopulmonary window (APW) is a rare congenital opening between the aorta and the pulmonary trunk just above the aortic valve.

It is associated with other abnormalities in approximately 1/2 the cases, such as anomalous origin of the coronary arteries from the pulmonary trunk and coarctation of the aorta.

The murmur is lower and more medial in location. In adults is presented without a murmur and clinical features of the Eisenmenger's syndrome.
