Single coronary artery: a case report

Abstract

Abstract. 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.
