Single coronary artery: a case report

In single coronary artery anomaly, there is single coronary artery ostium from which both coronary arteries arise with essentially normal peripheral distribution. In this case, we presented a 50-year-old male patient with single coronary artery who underwent coronary angiography. A 50 year-old caucasian male patient referred to the hospital for evaluation of palpitation and atypical chest pain. Myocardial perfusion scintigraphy (MPS) imaging revealed a mild ischemia at the midanteroseptum. We performed a cardiac catheterization and coronary angiography demonstrated a single coronary artery originating from the right sinus of Valsalva. Isolated single coronary arteries are relatively rare anomaly with a variable clinical presentation. This anomaly occasionally has been associated with sudden death. The case is interesting because of MPS demonstrated mild mid-anterior septum ischemia but coronary angiography images revealed no stenotic lesions and the single coronary artery did not travel in between the aorta and pulmonary artery.
