ABSTRACT:<\/strong><\/p>\n

Introduction:<\/strong> Coronary arteries supply oxygen rich blood to entire heart muscle, Arterial supply to heart is achieved by two arteries, which are the only branches from ascending aorta. These arteries branch in such a manner that they occupy atrioventricular and interventricular groove in the shape of a crown. Hence they are called the coronary arteries. The artery supplying the Posterior Descending artery (PDA) determines the coronary dominance. the right dominant coronary circulation is one in which the PDA is a terminal branch of Right Coronary Artery (RCA) and in left dominance, PDA arises from left coronary artery Left dominant hearts are at an increased risk of coronary heart diseases. The present survey was therefore conducted to find out the variations in termination and dominance of coronary arteries.<\/p>\n

Material and Methods:<\/strong> The material for the present study comprises of adult human heart collected from the cadavers from the dissection hall of anatomy department of S.V.S medical college, Mahabubnagar from 2007 to 2016. The hearts of 80 adult cadavers fixed with 10% formaldehyde , With the help of Scalpel ,\u00a0 Forceps, Scissors, I used Dissection method\u00a0\u00a0 To secure the heart specimen, then KOH method used To separate the heart\u00a0 muscle mass and for highlight the arterial system Fevicryl crimson red colour .For the Angiogram study,20 Coronary angiograms and 20 CT angiograms films were collected from the Department of Cardiology, Yashoda hospital, Secunderabad\u00a0 to compare the coronary arteries in the living with that cadavers.<\/p>\n

Results:<\/strong> Right coronary artery terminated as a 7.5% Before right border, 15%\u00a0 At right border,\u00a0 22.50%\u00a0 Before Crux\u00a0 and 55% At crux or beyond crux .Left coronary artery terminated as a15%\u00a0 At Apex ,85%Lower 1\/3rd\u00a0 of\u00a0 Posterior IV groove.and Right Coronary Artery Dominance were found in\u00a0 70% hearts ,Left Dominance were found in 15% hearts and Balanced\u00a0 were found\u00a0 in 15% hearts.<\/p>\n

Conclusions:<\/strong> Better anatomical knowledge about the dominance of coronary artery and its variation is essential for cardiologists and interpretation of coronary angiograms by radiologist.<\/p>\n

Key words<\/strong>: Right coronary artery (RCA)\u00a0 Left coronary artery (LCA) ,\u00a0 Posterior Descending Artery (PDA) , Dominence.<\/p>\n
