Tetralogy of Fallot with Double Aortic Arch in an 8-Month-Old Girl: A Rare Association.

Double aortic arch (DAA) is an extremely rare congenital anomaly that can be divided into right dominant, left dominant, and balanced DAA according to the relative size of the two arches. The incidence of balanced DAA is only 5% among double arch anomalies. DAA is symptomatic only when it produces symptoms secondary to compression of the trachea or esophagus. DAA is rarely associated with other congenital heart diseases. In this report, we present a rare case of asymptomatic DAA combined with Tetralogy of Fallot (TOF) in an 8-month-old girl.
