Abstract
Congenital left ventricular diverticulum is a rare cardiac abnormality consisting of a localized outpouching from the free wall of the cardiac chamber. It is usually asymptomatic. However, complications such as infective endocarditis, arrhythmias, and embolism may occur. Medical ultrasound, echocardiography, CT angiography, MRI and invasive ventriculography are diagnostic tools used to identify congenital left ventricular diverticulum. Surgical resection is the treatment of choice in symptomatic patients, whereas the management of asymptomatic patients often represents a therapeutic dilemma. We report the case of a symptomatic left ventricular diverticulum on a 3-day-old female with Cantrell’s syndrome treated surgically. Postoperative course was uneventful. The patient was discharged with a good clinical condition. The prognosis of this malformation is poor if not diagnosed in the perinatal period. A diagnosis can be suspected with echocardiography; however, a CT scan allows a complete study of the problem. The treatment is always surgical with a good postoperative prognosis.

This is from the left ventricular apex; non-apical diverticula may occur[1]
Ventricular diverticulum is usually associated with a thoracoabdominal wall defect as seen in the spectrum of Cantrell’s pentalogy[1,2]
Summary
Congenital left ventricular diverticulum is a rare cardiac abnormality, consisting of a localized out pouching from the free wall of the cardiac chamber. Ventricular diverticulum is usually associated with a thoracoabdominal wall defect as seen in the spectrum of Cantrell’s pentalogy[1,2]. This study reports a rare case of a left ventricular diverticulum on a new born infant with Cantrell’s syndrome. The contrast enhanced multi-slice CT showed a thin walled channel extending up from the left ventricular apex to the anterior abdominal wall (Figure 2). This diverticulum was 6cm long following the abdominal midline through a defect of the anterior diaphragm and extending up to the umbilical region (Figure 3). At a 6 month follow-up examination, the infant had a good clinical condition and a normal cardiac function on echocardiography
