Study of Right Marginal Artery in Adult Human Hearts of Hyderabad Karnataka Region.

ABSTRACT

Background and objectives: Coronary artery anomalies are known to be associated with congenital heart defects, myocardial ischemia and reduced life expectancy. The sound knowledge of coronary artery anatomy is necessary for proper management of patients undergoing evaluation for percutaneous coronary intervention, coronary artery surgery or prosthetic valve replacement. The present study is done to determine the origin, course and variation of right marginal artery for proper diagnosis and treatment of the heart diseases. Materials and Methods: The present study is done on 76 adult heart specimens obtained from routine dissection conducted for undergraduate students in the Department of Anatomy at Bidar Institute of Medical Sciences, Bidar and also from other nearby medical colleges of Karnataka and Maharashtra. The data obtained is tabulated and analysed statically. Results: In our study it is observed that the right marginal artery is present in 88% cases and is absent in 12% cases. Right marginal artery terminates before inferior border in 19%, in between inferior border and apex in 78%, and in 3% cases right marginal artery terminates at apex. Conclusion: The present study is done to know the normal and variant anatomy of right marginal artery in Hyderabad Karnataka region to provide vital inputs for making a correct diagnosis and planning treatment for procedures like coronary angiography, stenting procedures and surgical myocardial revascularization as the right marginal artery terminating at apex can irrigate the inferior third of heart, diaphragmatic area limiting the possibility of ischemic process in the occlusion of anterior interventricular artery.
