ABSTRACT<\/h3>\n

Background<\/strong>: Among heart diseases, coronary artery disease is one of the major causes of death in developing countries. Coronary circulation studied by various methods has demonstrated that there is a huge spectrum of variation in the branching pattern of the coronary arteries. Blood supply of the heart is achieved by two coronary arteries originating from the ascending aorta. In present study we prepare casts of coronary arteries by using corrosive cast technique to study the origin, course, termination and branching pattern of right coronary artery with its variations in human hearts.<\/p>\n

Materials and Methods:<\/strong> 30 fresh specimens of human hearts which were obtained from the post-mortem room, B.J.Medical College, Ahmedabad. The cannula with cone shaped tip was introduced into both the coronary arteries through the coronary ostia. The lumen was cleaned and after that prepared resin was instilled in coronary ostia. After 24 hours the heart specimen was immersed in concentrated HCL. 30 casts of coronary arteries were prepared and observed.<\/p>\n

Results:<\/strong> In All the specimens the right coronary artery ostium was present in the right anterior aortic sinus. Termination of RCA was found at the crux and beyond crux in 21 specimens (70 %); at the right border in 3 specimens (10 %) and at the left border in 5 specimens (16.66 %). right marginal artery terminated at the apex in 23 specimens (76.66 %) and near to the apex in 7 specimens (23.33 %). The PIVA arose from the RCA in 27 specimens (90 %) and from the LCA in 3 specimens (10 %). In 25 specimens (83.33 %). the sinu-atrial nodal artery was found to be originating from RCA and in 5 specimens (16.66 %) it originated from the LCA<\/p>\n

Discussion:<\/strong> Anatomical variations of the coronary arteries are important, as decisions with regard to revascularization procedures in many cardiovascular diseases depend on knowledge of the anatomy of each individual artery. Knowledge of the normal and variation in branching\u00a0 pattern of right coronary artery is helpful to anatomist, \u00a0radiologist and cardiologist as this is important for the interpretation of coronary angiography, \u00a0various shunt surgery and stenting procedures.<\/p>\n

Key word<\/strong>: Right Marginal Artery, Posterior interventricular Artery, Sinu-atrial Nodal Artery, Corrosive Cast.<\/p>\n
