Truncus arteriosus revisited: an angiographic demonstration

Abstract

The 1965 reclassification of truncus arteriosus by Van Praagh and Van Praagh greatly enhanced our understanding of this interesting anomaly. This brief review article attempts to illustrate the various types of truncus arteriosus identified in this classification by demonstrating their angiographic features. Reemphasis of the usefulness of this classification should help students of congenital heart disease recognize the advantages of a uniform diagnostic approach to this entity.
