Multi-modality imaging of an unusual congenital left ventricular diverticulum.

The authors describe the case of a newborn presenting with a pulsatile abdominal mass that was subsequently diagnosed as a large congenital muscular left ventricular diverticulum. This case illustrates the role of multimodality imaging in the diagnosis and surgical planning of this rare congenital heart disease. The diverticulum was managed with surgical resection without the use of cardiopulmonary bypass. Unlike in previous case reports, this patient did not have any associated intracardiac defect.
