ObjectivesTo display the prevalence rate of the coronary artery anatomical variations & congenital anomalies in 1000 patients of the Egyptian population using multidetector computed tomography (MDCT) exhibiting its diagnostic capability.Patients & methodsMDCT angiography was used to examine 1000 patients (clinically suspected patients with CAD & others with suspected congenital cardiac anomalies). Coming fasting, non-contrast cardiac CT was carried after intravenous injection of contrast material & ultra-thin cardiac scanning. Images were analyzed with MPR, cMPR, MIP & VR. The data of coronary artery variations and anomalies were gathered.ResultsAmong 1000 patients, most of patients (88.7%) had right coronary dominance. Type III LAD was the most prevalent (77.4%). Most of patients (47.3%) had two diagonal branches arising from the LAD. The incidence of congenital anomalies was 18.9%. Myocardial bridging was the most frequent reaching 16.8% (88.9% among all anomalies).ConclusionWide range of variation was noted among the examined population. Satisfying imaging capability of MDCT was encountered making it an essential tool for assessing coronary artery variants and anomalies before coronary revascularization being accurate & less invasive than conventional angiography
