Abstract
Bothaina Mohammed Abdulshakour,1 Muhammad Saeed,2 Mohiuddin M Taher3,41Department of Radiology, Al-Noor Specialist Hospital, Makkah, Saudi Arabia; 2Faculty of Medicine, Department of Radiology, Umm-Al-Qura University, Makkah, Saudi Arabia; 3Department of Medical Genetics, Umm-Al-Qura University, Makkah, Saudi Arabia; 4Science and Technology Unit, Umm-Al-Qura University, Makkah, Saudi ArabiaPurpose: This article reports the case of a single coronary artery with origin from a single ostium in the right sinus of Valsalva (RSOV) with an anomalous course of the left coronary artery anterior to the pulmonary trunk.Results: We present the case of an anomalous single coronary artery detected incidentally during routine coronary computed tomography (CT) angiography performed by a multislice CT method, using a 64-detector-row scanner. The CT examination revealed that the patient had a single large right coronary artery arising from the right sinus of Valsalva, dividing into the right coronary artery, left main coronary artery (LMCA), and left circumflex artery (LCX). The LMCA turned anteriorly in front of the pulmonary outflow tract, reaching the atrioventricular groove. The LCX artery passed posterior to the aorta (retro-aortic) and then between the left atrium and left ventricular outflow tract to reach its normal course on the left side.Conclusion: We present a rare case of single coronary artery congenital anomaly from the Makkah region of Saudi Arabia. This kind of coronary artery anomaly in the absence of stenosis could remain silent and asymptomatic.Keywords: anomalous single-coronary artery, multislice CT (MSCT), solitary coronary ostium, cardiac computed tomography (CCT), coronary angiography, coronary-computed tomography (CT)-angiography
