Background: Left main coronary artery divides into left anterior descending and circumflex arteries. Total occlusion of the left main coronary artery without extensive MI and cardiogenic shock is a rare finding. Case: The patient is a 50-year-old man that had referred to doctor’s office with history of exert ional chest pain two months earlier. Although he did not have history of rest angina, he had history of smoking as well as positive family history for coronary artery diseases. Exercise test with echocardiography revealed significant S-T depression. Hence, coronary angiography was done for the patient which showed total occlusion of the left main and originated left circumflex artery from right coronary artery and left anterior obliq filled from right coronary artery. The patient was candidate for coronary artery bypass graft. Conclusion: Total occlusion of the left main coronary artery without cardiogenic shock and death is a rare finding. This phenomenon occurs when occlusion is chronic and it is followed by right coronary artery with well-developed collateral which might be presented with stable angina. The mainstay treatment for total occlusion of the left main coronary artery is coronary artery bypass graft
