A Study of Dominance Patern In Coronary Circulation In Cadaveric Human Hearts
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 9
Abstract
Anatomy of coronary arteries and its variation is significant for proper interpretation of coronary angiographies as well as for procedures like surgical myocardial revascularization. Dominance pattern of heart has important clinical significance. Left dominance is found to have significantly higher mortality than right dominance and the balanced pattern, as major part of the heart is supplied by LCA in such cases [5]. In right dominant heart where the RCA supplies AV node, an occlusion of RCA will have higher risk of AV block [6]. Balanced pattern is associated with less mortality. In this present study we aim to study the dominance pattern in coronary arteries by tracing the origin of posterior interventricular artery (PIVA). 100 adult human hearts irrespective of age, sex, socio economic status or religion were collected from cadavers in Anatomy department and also from bodies that came for post-mortem in Forensic department that were preserved in 10% Formalin at our institute were used for the study. Results analysed and discussed. The data obtained from this study will help Cardiologists and Cardiovascular surgeons in proper correlation of angiograms and also in planning of treatment strategy in coronary heart diseases.
