Aortopulmonary window (APW) is a faulty connection between the aorta and the main pulmonary artery that results in a significant left-to-right shunt.[2] The aortopulmonary window is the rarest of septal defects, accounting for 0.15-0.6% of all congenital heart malformations.[4] An aortopulmonary window can develop alone or in up to 50% of cases alongside other cardiac defects such as interrupted aortic arch, coarctation of the aorta, transposition of great vessels, and tetralogy of Fallot.[3]
