A 60 year old man was admitted to our hospital with severe one hour typical chest pain. He has been smoking for 30 years one packet a day. He had not any other coronary artery disease risk factor. The ECG showed normal sinusal rhythm and ST-T changes in leads V1-V6. The chest X-Ray showed normal cardiac silhuette. There was no pathological finding on biochemical and haemathological blood tests except low HDL and slightly elevated trigliseride level (TG) (Total cholesterol: 190 mg/dl, LDL:110 mg/dl, HDL: 30 mg /dl, TG: 250 mg/dl). On physical examination: Blood pressure was 120/85 mmHg and heart rate was 78/minute/regular. There was not any pathological finding on cardiovascular and the other system examination.

At the 12^th hour, a slight elevation was detected in cardiac spesific troponins. We performed coroner angiography. There was not any luminal narrowing on coronary angiography but, 1.5-2 fold luminal dilatation which previously described coronary ectasy was detected on the 1/3 proximal portion of the left anterior descending coronary artery (LAD). Especially on the left lateral projection, opaque substance formed as an unique appearance of an inflated PTCA ballon and this continioued until the 120^th frame (Figure 1 and Figure 2). Any lesion prodruding into the arterial lumen and coronary arterial dissection excluded by intravascular ultrasonography. Patogenesis of acute coronary synduome in our patient was unclear. But severe blood stegnation in the ectatic segment of LAD and thrombus formation and coronary slow flow due to microvascular atherosclerotic disease may explain the pathogenesis of the acute coronary syndrome.
