Aortopulmonary window is a communication, usually nonrestrictive, between the ascending aorta and the main pulmonary artery, in the presence of two semilunar valves. In most patients, there is little or no length to the communication, as the term window implies, while a ductus-like type of communication is rare. The aortopulmonary window is generally located in the left lateral wall of the ascending aorta, usually close to the orifice of the left coronary artery (Fig. 3.22.3); therefore it is not infrequent to find an anomalous origin of the coronary artery from the pulmonary artery, close to the edge of the defect.
