Abstract

Background: Coronary artery disease is one of the leading cause of mortality in developing countries like India .The increasing use of diagnostic techniques and therapeutic interventions need a thorough knowledge of the normal branching pattern of coronary arteries and its variation. Most of the area of the Heart is supplied by the Left coronary artery and this artery presents wide variation in the branching pattern. Since this is the most commonly affected artery and first artery to show blockage, this study was conducted.

Materials and Methods: 50 Heart specimens were examined in the Institute of Anatomy, Madurai medical college, Madurai.

Results:  Left coronary artery Bifurcation (70%), Trifurcation (26%) and Quadrification (4%). SA Nodal artery arises from LCA (22%). PIVA arises from LCA (10%)

Conclusion: Knowledge of variations in the branching pattern is useful for cardiologist and cardiothoracic surgeon for angiographic interpretation, stenting procedures and surgical myocardial revascularization.

Keywords:  Left coronary artery, Bifurcation, Trifurcation, Quadrification, Sino atrial nodal artery, Posterior interventricular artery.
