The anomalous origin of the right coronary artery from the left coronary sinus is a rare congenital disorder and can often result in sudden death upon initial presentation. We report a 19-year-old male patient who was referred to the Sultan Qaboos University Hospital, Muscat, Oman, in 2015 with multiple episodes of exertional angina. He was diagnosed as having an anomalous right coronary artery arising from the left coronary sinus following an intraoperative transesophageal echocardiogram. An unroofing ostioplasty of the anomalous right coronary artery was successful. Details of the surgical management of this anomaly are discussed.
