Ventricular aneurysm Report of a case occurring in a 16-year-old boy with granulomatous myocarditis

A report is made of the case of a 16-year-old boy with a ventricular aneurysm complicated by a grand mal seizure and several episodes of paroxysmal ventricular tachycardia. The aneurysm was successfully excised, with the aid of cardiopulmonary bypass. A granulomatous myocarditis was found during microscopic examination of the cardiac tissue removed at operation. The possible significance of this finding is not clear, and we could not determine whether the granulomatous myocarditis was the direct cause of the aneurysm or whether it represented a response to a previous injury to the myocardium.
