Left ventricular aneurysm of unusual aetiology: report of two cases.

Two young patients aged 14 and 25 with left ventricular aneurysms are described. In both, a clinical picture initiated by attacks of supraventricular tachycardia led to the discovery of the condition. In the first patient the clinical picture clearly suggested a traumatic aetiology. In the second, the angiographic and histological findings strongly favoured a congenital origin. Both patients underwent successful aneurysmectomy. The literature on the incidence and aetiology of traumatic or congenital ventricular aneurysms is discussed.
