IntroductionCoronary artery anomalies are rare [1][2][3] though Anderson [4] in Grants Atlas of Anatomy states that the coronary circulation is extremely variable in detail. Coronary artery anomalies have a documented incidence range of between 0.26 % to 5.64 % in studies done using different methods in different countries [1,[5][6][7][8][9][10][11][12]. Altin et al., [12] reported that the incidence of coronary artery anomalies (CAAs) varies from 0.2% to 8.4%. With the increase in the rate of cardiovascular diseases in developing countries [13] and Sub-Saharan Africa [14], knowledge of the normal and possible variations in the origin and course of the coronary arteries is indispensable and imperative in diagnosis, treatment and implementation of interventional measures [3,15,16]. Knowledge of the possible variations in the origin and course of the major coronary arteries can greatly enhance clinical outcomes [3]. Recognition and knowledge of coronary artery anomalies is important when performing angiographies and ensuring accurate angiographic interpretation [7,16].
