We described the clinical, hemodynamic and angiographic findings of two patients who had complete occlusion of the left main coronary artery which occurs roughly in one out of 1000 patients undergoing coronary arteriography. Left main coronary artery was completely occluded after a short proximal segment in one of the patients (A.Y.). Rihgt coronary artery was dominant, and there was a significant narrowing in the posterolateral branch. There were extensive collaterals from right to left. Distal branches of the left coronary system were visualized via the collaterals from right to left in both patients. One of the patients (A.Y.) had poor left ventricular function and ventricular tachycardia episodes were seen soon after the angiography, which were resistant to various antiarrhythmic agents. Both of the patients underwent coronary bypass surgery. One of them (A.Y.) had exercise induced angina pectoris in the 8th month of the postoperative follow-up period.
