Rare Case of Aortopulmonary Window With Anomalous Origin of Right Coronary Artery.

A 5-month-old infant presented with a rare, congenital heart disease: aortopulmonary window with an anomalous origin of the right coronary artery from the aortopulmonary window. Using echocardiography and computed tomography, the exact diagnosis could only be ascertained retrospectively; however, cardiac catheterization and angiography confirmed the diagnosis, which led to elective open-heart surgery. The infant made a full recovery.
