Coronary artery anomalies are rare in population and most of them are found incidentally during coronary angiography. Percutaneous treatment of critical lesions on anomalous arteries may lead to difficulties due to their abnormal origin or course. Herein, we report a 65-year-old male patient presented with recent onset chest pain. Electrocardiogram and transthoracic echocardiography were in normal range. Treadmill exercise test revealed ST segment depression in lead V-4-V-6. Angiography revealed an unusual coronary anomaly: twin circumflex arteries originating from left main coronary artery and same orifice of right coronary artery, respectively. There was a significant stenosis on the right sided circumflex artery, which was treated percutaneously via transradial access.
