83 - Interruption of the Aortic Arch

Abstract

Interruption of the aortic arch (IAA) is a very rare congenital heart disease (CHD); the initial sign raising suspicion is disproportion of the left and right ventricles. It can be very difficult to distinguish from aortic coarctation (AoC). The appearance of the aorta can vary according to the type of IAA. There is a high association with other cardiac and extracardiac anomalies. In isolated IAA, the prognosis is generally good, but long-term complications at the aortic repair site are possible.
