[Isolated congenital left ventricular diverticulum: report of a paediatric case].

Congenital cardiac diverticulum is a rare malformation formed by an outpouching of the ventricular wall, in particular the left ventricle. The thoraco-abdominal type is more frequent than the isolated thoracic type. Topographical and imaging considerations regarding an isolated congenital left ventricular diverticulum incidentally discovered in a 9-year-old-boy are reviewed.
