Adult presentation of interrupted aortic arch: case presentation and a review of the medical literature.

Interrupted aortic arch (IAA) is a rare congenital abnormality that presents in infancy. Isolated cases have been reported in adulthood, which are likely presentations of severe coarctation of the aorta. We present two such cases of adult presentation of IAA and a review of previously reported cases in the medical literature and current recommendations for management and follow-up of these patients.
