Coronary Dominance Pattern: An Angiography-based Preliminary Report from Eastern India

Abstract

We did a retrospective analysis of 102 coronary angiograms for coronary dominance. Right-dominant circulation was seen in 62 (60.8%) patients, whereas left-dominant and codominant circulation was seen in 25 (24.5%) and 15 (14.7%) patients, respectively. Regarding gender variations, among males 71.42% had right-dominant circulation, where it was left dominant in 20.63% and codominant in 7.93%. For females, right-dominant circulation was present in 43.59% of patients, and left-dominant and codominant circulation was present in 30.77% and 25.64% of patients, respectively.
