Interrupted aortic arch is a rare congenital heart malformation occurring in approximately three per 1 million births. Type B interrupted aortic arch (interruption between the second carotid artery and the ipsilateral subclavian artery) is the most common of three major types (A, B, and C). We report an extremely rare finding: a case of left-sided type B interrupted aortic arch with isolation of the right subclavian artery (origin from the right pulmonary artery).
