Isolated Single Coronary Artery Originating From A Single Right Coronary Ostium in A Patient with Non ST-Segment Elevation Myocardial Infarction

Single coronary artery is a rare congenital anomaly. In case of left main artery traveling between aorta and pulmonary artery sudden death can be occurred, although this does not usually effect coronary flow. We present a 63-year-old woman whose coronary angiography for typical chest pain revealed an isolated single coronary artery. On coronary angiography, the whole coronary system originated by a single trunk from the right sinus of Valsalva. A significant flow-limiting lesion was found in the right coronary artery that was successfully treated with percutaneous coronary intervention.
