Introduction: 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. Materials and Methods: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, Forceps, Scissors, we used Dissection method to secure the heart specimen, then KOH method used To separate the heart 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 to compare the coronary arteries in the living with that cadavers.Results: Right coronary artery terminated as a 7.5% before right border, 15% at right border, 22.50% before Crux and 55% at crux or beyond crux. Left coronary artery terminated as a15% at Apex, 85% Lower 1/3rd of Posterior IV groove.and Right Coronary Artery Dominance were found in 70% hearts, Left Dominance were found in 15% hearts and balanced were found in 15% hearts. Conclusions:Better anatomical knowledge about the dominance of coronary artery and its variation is essential for cardiologists and interpretation of coronary angiograms by radiologist.

Libman-Sacks endocarditis is the characteristic cardiac manifestation of autoimmune disease Systemic Lupus Erythematosus. The condition most commonly involves the mitral and aortic valves, but all the four cardiac valves and the endocardial surfaces can be involved 1. Persons with Libman-Sacks endocarditis are usually asymptomatic., but become symptomatic due to cardiac failure, cerebrovascular embolism, systemic thromboembolism and secondary infective endocarditis. 2D Echocardiography should be performed when it is suspected. With introduction of steroid therapy for SLE, improved longevity of patients appears to have changed the spectrum of valvular disease. Herewith, we are reporting a 35 year old female who presented at Department of General Medicine, GGH, Guntur with seven day history of anasarca, shortness of breath, cough and fever of long duration. ECHO was suggestive of Libman-Sachs endocarditis and further investigations revealed SLE. On addition of steroids, there was good response and the patient was improving, but she had sudden cardio-respiratory arrest 5 days later.
