ABSTRACT

Congenital cardiac diverticulum is a rare malformation formed by an outpouching of the ventricular wall, in particular the left ventricle. It's often associated with other thoraco-abdominal diverticulums, and rarely isolated. Clinical presentation is variable ranging from life threatening manifestations to being completely asymptomatic. The diagnosis relies on echocardiography. The magnetic resonance imagery (MRI) allows a finer analysis of the diverticulum, its topography and its situation contributed to vascular and cardiac structures, it has largely replaced the ventriculography. We present the case of a 9 year old child admitted for pericardial effusion. Echocardiography and CT scan revealed the presence of two left ventricular diverticula. The patient died suddenly before surgery. Autopsy was not performed. This case and the review of the literature underscore the importance of early diagnosis and prompt treatment of this potentially fatal pathological entity.
