Interrupted aortic arch is a very rare heart defect (affecting 3 per million live births) [1] in which the aorta is not completely developed. There is a gap between the ascending and descending thoracic aorta. In a sense it is the complete form of a coarctation of the aorta. Almost all patients also have other cardiac anomalies, including a ...
In either case, a variable degree of obstruction may be observed at the ventricular surface of the aortic valve. [1] This presents an obstruction of flow of blood from the ventricle to the aorta. Coarctation of the aorta which is, narrowing of a section of the aorta may also be observed. [1]
