Abstract

Complex coronary arteries variant and anomalies may affect adversely myocardial perfusion, diagnosis of these variant and anomalies may help surgeon to operate safely. This study was design to identify the 64-slice CTA appearance of the anatomic variations and anomalies of the coronary arteries and determine their incidence in our population. A retrospective study including of 202 persons 114(56%) males, 88(44%) females); age range 15-79 years who had underwent MDCT examination. The entire heart was scanned within a single breath-hold. Patients with coronary artery anomaly constituted the subject of study. The incidence of anomalies in females was 32.9% while in males was 38.6%. The prevalence of the RCA was dominant in 175 cases (86.8%), while the LCA was dominant in 24 cases (11.8%), and the incidence of co-dominance was observed in 3 cases (1.4%). The incidence of LMCA trifurcation was 35(17.32%) duplication anomalies were observed in one patient (0.5%) in which double LADA originated from LMCA. Variable number of diagonal branches arise from LADA where one diagonal in 67 patients (33.20%), two diagonal in 113(55.90%), three diagonal in 21(10.4%), no diagonal was observed in one patient (0.5%).
