Abstract:
The widespread application of coronary angiography and poen heart surgery have resulted in more frequent detection of patients with coronary artery anomaly. In 0.6 to 1.2 percent of individials, the coronary arteries arise aberrantly from the aorta. Anomalous origin of the left coronary artery from the fight coronary sinus with subsequent coursing between the aorta and pulmonary artery is a rare and sometimes fatal coronary amonaly. This anomaly has been reported in young and healthy men who died suddenly during or immediately forllowing vigorous physical exercise. The exact mechanism of sudden death is unclear. It is believed to be related to either extrinsic compression of the left coronary artery or distorsion of the vessel orifice, with resultant global ischemia and ventricular fibrllation. A 13-years old healthy boy, who was completely asymptomatic until he had sudden chest pain after running, arrived at hospital with typical clinical picture of acute myocardial infarction. The electrocardiography taken on admission demonstrated pathologic Q wave changes on lead I, aVL, V2, V3 and V4. Cardiac enzymes were elevated. The selective coronary angiography demonstrated that left coronary artery arose from the right coronary sinus. The anomalous left coronary artery passed posterioly around aortic root to reach its normal position in the interventricular groove. We report the patient with anomalous origined left coronary artery which causes the acute myocardial infarction.
