double aorta

double aorta

A congenital defect of the aorta in which both of the dorsal embryonic aortae persist and encircle the trachea and esophagus; after birth, and consequent to the aorta's growth in a region with limited space, the ring produces a relative constriction, resulting in stridor and dysphagia. Cf Double-barreled aorta.
