[Sudden death in a 4-month-old infant associated with anomalous origin of the left coronary artery].
We describe the autopsy findings of a 4 months-old boy, who died suddenly after an episode of high airway infection of 3 days time. Autopsy examination showed cardiomegaly (80 g) with widening of the left cavities and thick and white endocardial surface, besides a severe thinning of the cardiac apex at the level of the left ventricle. Left coronary origin was in the pulmonary artery trunk. Histologically, the myocardium shows endomyocardial fibroelastosis and also multiple and extensive areas of old and recent infarcts in the left ventricle. The collateral coronary arteries, were increased in number, and branches showed a marked intimal oedema and a reduction of the luminal diameter.
