Three-dimensional printing in surgical planning: A case of aortopulmonary window with interrupted aortic arch.

Better anatomical understanding and conceptualization of complex congenital heart defects using three-dimensional (3D) printing may improve surgical planning, especially in rare defects. In this report, we utilized 3D printing to delineate the exact cardiac anatomy of a neonate with an aortopulmonary window associated with interrupted aortic arch to devise a novel approach to the repair.
