ASSESSMENT OF CORONARY ARTERY DOMINANCE IN THE INDIAN CADAVERS

As Coronary artery disease is one of the most common heart diseases and also the major cause of death in developing countries. The aim of the present study is to evaluate the coronary dominance pattern which will help the cardiac physicians and surgeons for better diagnosis and management of coronary artery diseases. The study was planned on 30 heart subjects. These selected hearts are without any obvious pathology referred with cardiac conditions was enrolled into the study in Andaman and Nicobar Islands Institute of Medical Science (ANIIMS) from July 2016 to July 2017.The coronary arteries were dissected and analysed for the origin of sinoatrial Nodal artery and Observations were noted. The approval of the Institutional ethical committee was taken for the present study. The hearts identified with the congenital anomalies were excluded from study. From the above study it can be concluded that the most common is the right coronary dominance compared to left and balanced dominance as seen in this study. The present study is in comparison with the data generated by previous authors. This knowledge of normal anatomy and variations of coronary dominance will help interventional cardiologist, cardio-thoracic surgeons and radiologist to plan and provide proper management to patients.
