A Study of Course, Branches and Variations of the Coronary Arteries in the Human Cadaveric Heart
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 7
Abstract
Introduction: The myocardium is supplied by a pair of coronary arteries which arise from the ascending aorta. The term “Coronary” is derived from the Latin word “Corona”, which means crown. The heart pumps the blood for the entire tissues in the human body through the aorta. However, the heart itself gets its nutrition through coronary arteriesa. The present study was conducted to observe the origin, branching pattern, termination and variations of coronary arteries in human cadaveric hearts. Material and methods: The present observational descriptive study was conducted at Dept. of Anatomy; Government Medical College Yavatmal to observe the origin, course branching pattern and variations of the coronary arteries in human cadaveric hearts during August 2014 upto November 2016. Study includes hearts of adult cadavers from both genders (aged 25–70 years) that were fixed with 10% formaldehyde which were collected and used for the present study. Ethical clearance from college Institutional Ethical Committee was obtained. Results: In all 50 cases, the dissected (RCA) right coronary artery arose from the anterior aortic sinus. Left coronary artery was found to arise from left posterior coronary sinus in 49 hearts and in one heart from right posterior sinus of the ascending aorta. In anterior aortic and left posterior sinus one opening was present in 35 (70%) and 46 (84%) cases respectively. Conclusion - It was observed that in 45 (90%) cases where the right ostia were situated just below the sinutubular ridge.
