ICD-11

A congenital cardiovascular malformation of the great arteries (aorta, pulmonary trunk [main pulmonary artery], branch pulmonary arteries) or the arterial duct (ductus arteriosus).

A congenital cardiovascular malformation in which there is side-to-side continuity of the lumens of the ascending aorta and pulmonary trunk in association with separate aortic and pulmonary valves or their atretic remnants.

Additional information: side-to-side continuity of the lumens of the aorta and pulmonary arterial tree, which is distinguished from common arterial trunk (truncus arteriosus) by the presence of two arterial valves or their atretic remnants, and involvement of the pulmonary trunk (main pulmonary artery).
