Abstract
A 14-year-old boy, admitted with intractable chest pain, was found to have an enlarged heart and calcification in the apical region, with electrocardiographic features of massive inferolateral myocardial infarction. Left ventricular angiography revealed a large left ventricular aneurysm. He died following resection of the aneurysm and post mortem examination showed changes of a non-specific chronic myocarditis. A vasculitis involving small coronary arterioles was also found in the vicinity of the aneurysm, and the possibility of a rheumatic vasculitis was suggested by a transient episode of an erythema marginatum-like eruption. It is concluded that the association of infarction pattern on the electrocardiogram together with calcification of the heart in children is highly suggestive of a ventricular aneurysm secondary to a myocarditis or a vasculitis involving small, intramyocardial branches of the coronary arteries.
