Anatomical assessment of prevalence of origin of coronary artery in cadaveric hearts from Bihar region
Dr. Amrendra Prasad Sinha, Dr. PK Verma
The term right or left “Coronary Preponderance” or “Dominance” was used to show which coronary artery irrigates the heart's diaphragmatic surface, based on the origin of the 3 posterior interventricular arteries. Thus a region specific study of the coronary arteries would help both cardiac surgeons and radiologists in dealing better with the coronary heart disease. Hence the present study was planned to evaluate the origin of the coronary artery in cadaveric samples from Department of Anatomy, Anugrah Narayan Magadh Medical College, Gaya. The present study was planned in the Department of Anatomy, Anugrah Narayan Magadh Medical College, Gaya, Bihar. The study was performed from the duration of Dec 2018 to Jan 2019. The total 15 Normal hearts with age groups 20-70 years of both sexes were included, while hearts weighing more than 370 gms. in males and 280 gms. in females, heart specimens in cadavers of age more than 70 yrs. and less than 20 years, grossly abnormal hearts were excluded. Cadaveric Heart specimen was immersed in 10% formaldehyde to preserve it. The heart was dissected and the coronary arterial dominance was noted. Schlesinger’s criteria was used to determine coronary dominance. The above results prove that there are wide regional variations in dominance pattern. These variations should always be borne in mind for better cardiac care. Knowledge about the variations of coronary arteries is helpful for cardiologists and radiologists in performing various procedures like coronary angiogram, coronary angioplasty, and bypass grafting surgeries etc.
