Abstract
“Persistence of the fifth aortic arch” is a rare congenital cardiovascular anomaly that consists of an abnormal vessel arising from the distal ascending aorta connecting with the systemic or pulmonary circulation. We report a case of a type A interruption of the aortic arch and a coarctation of the fifth aortic arch, which connected the ascending with the descending aorta. No cardiac surgery was required because a covered stent was successfully implanted in the fifth aortic arch when the patient was 4 years old. A chromosome 9 q arm duplication of uncertain significance was also found, an anomaly never described before in this clinical context.
