A cadaveric study of coronary arteriesin Rayalaseema population of Andhra Pradesh

Abstract

Introduction: Majority of the sudden cardiac deaths were due to anomalous origin and distribution of the coronary arteries. Aim: To study the arterial vascular pattern of the human heart by using dissection method in Rayalaseema population. Materials and Methods: A total of 80 human fresh heart specimens were obtained from the Department of Forensic Medicine, S.V. Medical College, Tirupati for the present study. Results: We have observed both the coronary arteries arising from single coronary ostia in 76 specimens whereas 4 heart specimens noted with coronary arteries originated from two ostia. Right and left dominance circulation was noted more in males than females. We have also observed double posterior interventricular branches arising from the right and left coronary arteries showing the balanced type of coronary circulation in 2 (Male-1; Female-1) hearts. Conclusion: Arterial pattern and its variations are important to prevent false interpretation of the arterial angiograms in management of coronary artery diseases.
