Interruption of aortic arch and hypoplastic left heart syndrome.

Interruption of the aortic arch and hypoplastic left heart syndrome in the same patient is exceptional. In the combined collections of the Registry of Cardiovascular Disease (St. Paul, Minnesota, U.S.A.) and the Registry of Congenital Heart Defects of the Rijksuniversiteit Gent (Gent, Belgium) three specimens were found with this unusual combination. These cases are herein described and compared with four similar cases previously reported in the literature.
