Cardiac magnetic resonance findings in isolated congenital left ventricular diverticuli.

Congenital ventricular diverticulum is a rare cardiac abnormality, frequently associated with other cardiac or non-cardiac congenital malformations. Clinically, congenital ventricular diverticulum may be asymptomatic or cause systemic embolization, heart failure, ventricular rupture, ventricular arrhythmia and sudden death. Cardiac magnetic resonance (CMR) can be a useful non-invasive and non-ionizing method to confirm the presence, size and extent of left ventricular (LV) diverticulum and its tissue characterization. In these reports we documented the presence of six diverticuli in patients underwent to CMR for other clinical indications. In all the cases, magnetic resonance showed an accurate assessment of diverticuli.
