Detail knowledge of  normal and anomalous coronary anatomy is necessary to prevent misinterpretation & disastrous complications during increasing coronary intervention & cardiac surgery. Morphometric  Study of coronary arteries of 20 cadaveric hearts (both sexes) was done. 20 Cadaveric heart were dissected to study coronary arteries morphologically i.e. no. and position of ostia, length & type of division of left main trunk, & origin of Sino-atrial nodal artery. The incidence of right “DOMINANCE” was 75%, left “DOMINANCE” 10%, co-dominance 15%. In 4% cases two ostia were present for left & right coronary artery. Incidence of short left trunk (<5mm) was 10%, long trunk (>15mm) was 25%. In 15% left trunk was trifurcating (presence of median artery). In 90% cases sino-atrial nodal artery was originating from right coronary & in 10% from circumflex artery. Histological changes were present in 45% cases & significantly involving the proximal segment of anterior interventricular artery.
