Diagrams showing the three types of interrupted aortic arch. Type A (left) is
characterized by aortic arch interruption distal to the left subclavian
artery origin; type B (middle) is characterized by aortic arch interruption
between the origins of the left common carotid artery and left subclavian
artery; and type C (right) is characterized by aortic arch interruption
between the origins of the innominate and left common carotid arteries. Ao =
aorta, LCCA = left common carotid artery, LSCA = left subclavian artery, PA
= pulmonary artery, PDA = patent ductus arteriosus. (Reprinted, with
