The presence of both conditions in an individual has been reported in only two previous cases in the recent literature.1,2The diagnosis was made prior to death in one of these cases.1The purpose of this report is to describe the second case of persistent truncus arteriosus with associated aortic atresia in which the diagnosis was made premortem. Report of a Case A 3,200 gm (7 lb 1 oz) Negro male was born at term to a 16-year-old primigravida following an uncomplicated pergnancy and delivery.
