[myocardial infarction associated with anomalous origin of the left main coronary artery].

Coronary anomalies are those conditions characterized by the abnormal origin or course of the epicardial arteries. This generates challenges at the time of diagnosis by catheterization, which is why it is important that the cardiologist is related to these variations. The origin of the left coronary artery in the right sinus of Valsalva has a low incidence. It is reported the case of a patient with myocardial infarction who presented this anomaly with total thrombotic occlusion.
