Right aortic arch symptomatic in adulthood.

We present a patient with progressive dysphagia and shortness of breath due to a right aortic arch with aberrant left subclavian artery that became symptomatic in adulthood. Diagnosis was made after a delay because the possibility of a congenital anomaly was not considered when the patient presented with dysphagia. A review is given of the incidence, embryology, aetiology, diagnostic evaluation and management, as well as a discussion of other congenital aortic arch anomalies.
