Exclusion criteria: Known or diagnosed cases of anomalous coronary arteries. Angiographic views: Left anterior oblique (LAO) for the right coronary artery whereas right anterior oblique (RAO) and left anterior oblique (LAO) for the left coronary artery.Results: Right coronary artery dominant in 74% of cases, left coronary artery in 16.86% of cases and a co-dominant pattern in 9.14% of cases.Conclusions: Findings of this study in accordance with that of many other studies and standard textbooks available on the subject.
