Abstract

The purpose of this retrospective study is to describe the prevalence, size and location of left ventricular (LV) diverticulum- diverticuli on cardiac dual source CT. Dual source computed tomography cardiac angiography (DS CTCA) was performed in 482 patients. Where literature states their rare occurrence, this retrospective study demonstrates the fairly common finding of incidental LV diverticulum on DS CTCA examinations. LV diverticuli were found incidentally in 20 out of 482 patients (4.1%), a substantially higher incidence than previously reported. Although diverticuli were most common along the inferoseptal wall (45%) they also occurred in all parts of the left ventricular wall. Multiple diverticuli were found in 30% of patients. Dimensions of the LV diverticuli varied enormously. LV diverticuli are reported to be frequently associated with other congenital anomalies. Complications ranging from sudden death and heart failure to embolic events have been described in literature. No relevant associated anomaly or complication was present in the studied 20 patients. Our data support the hypothesis that LV diverticuli, incidentally found in adulthood, follow a benign course and can be managed conservatively. More knowledge is however required to understand history and prognosis about this condition.
