Aortic arch interruption in infancy: radio- and angiographic features.

The radio- and angiocardiographic characteristics of 19 infants with an interrupted aortic arch were reviewed. There were three with type A (distal to the left subclavian artery), 15 with type B (between the left carotid and subclavian arteries), and one with type C (between the innominate and left carotid arteries). Associated cardiovascular anomalies were numerous, a ventricular septal defect (19/19) and a patent ductus arterisous (18/19) being the most common.
