    Abstract:
    Three infants with anomalous origin of left coronary artery, being two from the right pulmonary artery and one from the left, without other congenital defects, ages of 5, 15 and 3 months old, presented with early congestive heart failure due to anterolateral myocardial infarction. Anatomical characteristic was peculiar in two cases since the left coronary artery, before the anastomosis with the right pulmonary artery, presented a wy, 15 mm extension path within the aortic wall which has facilitated the surgical correction by the proximity of these structures. In the third case, the left coronary artery was anastomosed with the left pulmonary artery, 2 cm from its origin and anterior to the left atrium being the surgical correction by direct implant at the ascending aorta. Post-operative follow-up, 36, 30 and 33 months respectively, showed clinical and laboratorial normalization except for the second case in which ST segment remained upward due to ventricular aneurysm. Myocardial recovery, even after extensive infarction, in this anomaly, emphasizes the need for earlier diagnosis and management.
