A Study ofAnatomical Variations ofCoronary Arteries inNorth Indian Population
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 2
Abstract
The human heart is vascularized by right and left coronary arteries. The current study was done to assess the normal patterns of coronary arteries with reference to its predominance, branching pattern, variations and anomalies.Fifty two adult North Indian cadaveric hearts from both genders fixed with 10% formalin were obtained from the Department of Anatomy, King George’s Medical University, Lucknow, Uttar Pradesh, India. The exit points and various branching patterns of right and left coronary arteries were observed.Right coronary artery was originating from the anterior aortic sinus in 100%while left coronary artery took origin from left posterior aortic sinus in 96.15% and anterior aortic sinus in 3.85%.Right coronary artery gave origin to right marginal artery in 96.15% while absent in 3.85% specimen. Posterior interventricular branch coming from right coronary artery was noted in 92.31%. Accessory posterior interventricular branches were also seen in 11.54%. SA Nodal artery was noted in 34.62%, right conus artery in 57.69% and third coronary artery in 19.23%.Termination of left coronary artery was seen as bifurcation in 65.38% while trifurcation in 34.62%. Left marginal artery, a branch of circumflex artery was visualized in 15.38% specimens. Right dominance was present in 88.54%, left dominance in 7.69% andco-dominance was present in 3.85% specimens. Variations in branching pattern of coronary arteries as reported in present study necessitate its importance for proper diagnosis and management of coronary artery disease.
