Angiographic analysis of morphometry pattern of human coronary arteries

Abstract

Background: Coronary arteries play an important role in perfusion of the heart tissues. Variations or anomalies in coronary arteries may be asymptomatic while some can be symptomatic and even cause sudden death. Knowledge of coronary artery variations is important in diagnosis and treatment of cardiovascular diseases. Aim: To study the  angiographic analysis of morphometry pattern of human coronary arteries Materials and methods: We dissected and grossly examined a total of 78 human hearts to describe coronary artery variations in origin and course.  The study was carried out at Dr V.R.K Womens medical and Deccan College of Medical Sciences during the period from Jan 2018  to June 2019.Results and discussion: Diameter of LCA was 4.14 + 0.81, LAD was3.12 + 0.58, LCx was 2.28 + 0.48, and diameter of RCA was 3.10 + 0.38. Bifurcation of LCA was seen in 40 (80 %) males and 42 (84%) females. Trifurcation of LCA was seen in eight (16%) males and six (12%) females. two male (3.92 %) and two (3.92 %) females have quadrification of LCA. Length of LCA was significantly high in females (p < 0.00) and diameter was more in males (p < 0.01) when compared to females. However, there was no significant difference across gender in angle of division of LCA.Conclusion: Knowledge of the normal and variant anatomy of coronary arteries is indispensable and imperative both in diagnosis, treatment and implementation of interventional measures
