CORONARY ARTERY DOMINANCE – A CADAVERIC STUDY WITH CLINICAL PERSPECTIVES
Journal Title: IJAR-Indian Journal of Applied Research - Year 2017, Vol 7, Issue 9
Abstract
Background of study: In the clinical scenario of increasing the coronary artery disease, the knowledge of coronary artery dominance in Keralite population will be helpful to clinicians for planning interventional procedures and surgeries. Materials & methods: A cadaveric study over a period of three years was carried out in fifty human hearts to see the origin of posterior descending artery (PDA), after manual removal of epicardium and subepicardial fat. Results: Right coronary dominance was noticed in 76% of cases where as left coronary dominance and co-dominance were detected in 20% and 4% respectively. Summary: RCA dominance (76%) was the most prevalent pattern. There was no gender based variation in coronary artery dominance. Double PDA was detected in 2% of specimens. A sound knowledge of coronary artery dominance is essential before planning angioplasty and bypass surgery ofcoronary arteries since the left coronary dominance is associated with increased incidence of myocardial infarction as per literature.
