ABSTRACT:
Introduction: With the increase in the trend of modern sedentary lifestyle, the coronary heart diseases have also increased. The need to understand coronary artery anatomy in detail has become ever so important because of wide variations in the anatomy and various anomalies noted in different populations. Knowledge of coronary dominance is important to understand the severity of coronary artery diseases and plan the treatment of cardiovascular diseases. It determines the amount of myocardium that is perfused by the left or right coronary circulation.
Materials and Methods: 100 adult formalin fixed heart specimens were collected from routine under graduate and post graduate dissection at Belgaum Institute of Medical Sciences, Belagavi irrespective of sex and age. The origin of posterior interventricular artery was examined and dissected. Results were noted and compared with previous studies.
Results: Out of 100 specimens studied in 83 (83 %) specimens the posterior interventricular artery was arising from right coronary artery and in other 17 (17%) specimens it arose from Left circumflex artery. In none of the specimens studied the posterior interventricular artery was arising from both the coronary arteries.
Conclusion: The knowledge of normal anatomy and variations of coronary dominance will help interventional cardiologist, cardio-thoracic surgeons and radiologist of North Karnataka region in proper management of patients.
KEY WORDS: Coronary Dominance, coronary artery disease, Left coronary dominance, Right coronary dominance, co-dominance.
