Congenital coronary anomalies are rare and often found incidentally on conventional coronary angiography (CCA) or by other non invasive technique. They may lead to sudden cardiac death. Non invasive coronary angiography is unable to detect all coronary anomalies in details especially those with complex anomalies. Computed tomography coronary angiography is able to demonstrate origin, courses and terminations of these anomalies more accurately. Evaluation of the prevalence and types of coronary artery anomalies in a group of patients referred for computed tomography (CT-CA) and determining the extent of atherosclerotic coronary artery disease among these patients. Angiographic data of 13611 patients undergoing CT- CA from January 2012 to June 2016 were analyzed to determine presence of coronary artery anomalies. Gensini score and calcium score were calculated to detect prevalence of atherosclerotic coronary artery disease. We reviewed 13611 patients scheduled for CT-CA, 127 (0.93%) had coronary anomalies. Mean age was 54.2 ± 10.5. Male gender dominated our patients with congenital coronary artery anomalies and represented 66.9% (85 patients). The most common coronary artery anomaly was origin and course 105 (82.7%) and the most common vessel affected was the RCA 63 (48.5%). Prevalence of double LAD was 8 (6.3%) and fistula was detected in 13 (10.2%). Prevalence of severe coronary artery disease in our patients was 20 % detected by Gensini score. Prevalence of coronary artery anomalies in our study is 0.93%. Prevalence of severe atherosclerotic coronary artery disease in our patients was 20 % detected by Gensini score
