Abstract
The number of patients with coronary artery diseases is increasing every year and is a leading cause of death worldwide. Coronary artery disease is caused by occlusion of one of the coronary arteries, which leads to decreased function of the heart and eventually leads to death. Therefore, a detailed study of coronary arteries is important for a better understanding of coronary pathophysiology and better management of coronary heart diseases such as myocardial infarction and angina pectoris. To see the morphology, morphometry of the coronary arteries. The study was done on 30 human cadaveric hearts collected from the Department of Anatomy HIMSR JAMIA HAMDARD (NEW DELHI). Coronary arteries were dissected to see the origin, course and variations. In all specimens RCA was arising from anterior aortic sinus and LCA was arising from left posterior aortic sinus of ascending aorta. The length of RCA, PIVA, LCA, AIVA ranged from 80‐140mm, 40‐75mm, 10‐25mm and 111‐156mm respectively. Circumflex artery was seen only in 4 hearts. The length was between 50‐70mm.The diameter of RCA was measured in two segments. First segment was ranged from 3‐7.5mm and that of second segment was from 2.5‐6.3mm.The diameter of PIVA at the beginning was ranged between 2‐4mm and that of mid‐point was ranged from 0.1‐1.7mm. The diameter of the main stem of LCA ranged from 3.1‐ 7.7mm. The diameter of AIVA at beginning was ranged between 1.9‐6.5 mm and that of midpoint was ranged from 0.2‐2.9mm. Circumflex artery was seen only in 4 hearts. The diameter ranged between 2‐6mm. LCA bifurcates in 20 specimens and 10 shows trifurcation. This study directs the attention toward the importance of the coronary arteries and its main branches and branching pattern. The patterns obtained here may be clinically relevant during percutaneous coronary interventions or surgical revascularization.
