A case of an acute coronary syndrome associated with anomalous origin of the left main coronary artery, with a right coronary sinus origin

Abstract

We present a case whose left main coronary artery (LMCA) arose from the right sinus of Valsalva, which is a very rare congenital anomaly. In a 48-year-old male, coronary angiographic (CAG) examination revealed LMCA arising from the right sinus of Valsalva. Although this kind of anomaly has generally been accepted to have a benign course, it may cause sudden death. In this case report, we present a patient who was admitted to our clinic with Acute Coronary Syndrome (ACS) and was found to have LMCA originating from the right sinus of Valsalva in the CAG. A percutaneous coronary angioplasty was performed with stent placement in the critical stenosis in the left anterior descending (LAD) coronary artery.
