  • Case Report

Pediatric Cardiology Aims and scope Submit manuscript


Congenital left ventricular out-pouching, consisting of left ventricular aneurysms, left ventricle diverticulae, and double-chambered left ventricle, is a rare cardiac malformation. Criteria to differentiate between left ventricular aneurysm and diverticulum are defined. Reports of left ventricular accessory chamber in the medical literature are rare. In this article, we present a case of left ventricular accessory chamber diagnosed during the late prenatal period. Review of the literature, imaging modalities used for differentiation of the nature of this lesion, and management plan are discussed.
