Abstract :

The knowledge of normal and variant anatomy of coronary arteries is important in management of congenital and acquired heart diseases. Simple attention to potential variations in the origin and course of major coronary arteries can greatly enhance clinical outcome, hence, present study is designed to see the normal anatomical distribution and variation of the right coronary artery in the humanheart.50 cadaveric human heart specimens (25 male and 25 female) were used by dissection method. RCA arises from anterior (right) aortic sinus in 96% (48% male 48% female) specimens while in 4% (2% male & 2% female)it arose from left posterior aortic sinus along with LCA. In 52% specimen(28%male&24%female) RCA gave SA nodal anch, while in88% specimen (44%male & 44% female) it gave AVnodal anch. Right Conus Artery was traced in 82% specimen (36% male & 46% female). Posterior Interventricular Artery was anch of RCA in 86% specimen (42% male & 44% female). In the observation on the level of termination of RCA it was terminated at crux 34% and beyond the crux in 56%. It terminated at right boarder in 6% cases. In only one specimen (female) it was terminated between right boarder and crux. In another one specimen (female) it was terminated before right boarder. The course of RCA was found to be in all specimens except one in which it was found that immediately after its origin RCA was divided in to two arteries of same caliber.
