It consists of creating an aortopulmonary window and the flow between the RCA ostium and the aorta is established using an intrapulmonary tunnel [8, 14, 15].
Contrast enhancement chest CT, performed in the portal venous phase as our usual staging protocol, reveals that the left upper pulmonary vein presents an anomalous route: it first runs under the left pulmonary artery, then goes up medially to it, runs via the aortopulmonary window, and finally joins the left brachiocephalic vein, describing on the whole a curved line with superior concavity (Figures 1 and 3).
Most cases of type B were actually aortopulmonary window defects, and as such type B classification is no longer used [4].

ARCAPA may be associated with other congenital and acquired heart diseases, including aortopulmonary window, truncus arteriosus, anomalous subclavian artery, tetralogy of Fallot, constrictive pericarditis, bicuspid aortic valve, and mitral regurgitation [7, 9-15].
Some reports have found its association with tetralogy of Fallot, complete atrioventricular septal defect, and aortopulmonary window, which arises secondary to failure of septation in the aorticopulmonary trunk.
Aortopulmonary window (APW) is a relatively rare congenital disease consisting of a septal defect between the ascending aorta and the pulmonary artery, creating a left-to-right shunt (1-4).
