A prenatal diagnosis of unusual aortopulmonary communication: tubular aortopulmonary window

Cardiol Young. 2021 Aug;31(8):1327-1329. doi: 10.1017/S1047951121002225. Epub 2021 Jun 4.


We described a very rare case of aorto-pulmonary communication with right aortic arch and crossed pulmonary artery that cannot be placed in the typical anatomic classification of aortopulmonary window. At 23 weeks gestation, fetal echocardiography revealed a large tunnel-like communication connecting the great vessels proximal to the main pulmonary artery bifurcation, rather than a classic aortopulmonary window between the ascending aorta and the main pulmonary artery.

Keywords: Aortopulmonary window; cardiac anomalies; fetus; prenatal; right aortic arch.
