Analysis of Coronary Artery Anomalies and Variants in Cardiac Risk Groups Through Coronary Computed Tomography Angiography

Aim The purpose of this study is to investigate prevalance of coronary artery anomalies and variants in a cardiac risk group by using coronary computed tomography (CT) angiography. Materials and Methods Coronary CT angiography scans were retrieved for 527 consecutive adult patients (265 male, 262 female) with a preliminary diagnosis or suspicion of coronary artery disease between 2021 and 2023. Coronary artery anomalies and vascular variants were retrospectively reviewed. Results The study revealed that 85.97% had right dominant coronary circulation, 22.39% had myocardial bridging, and 9.3% having a ramus intermedius artery. Among the identified coronary anomalies, anomalies of origination and course were the leading causes (3.6 %), except for hypoplasia, which had a prevalence of 6.07 %. Overall, no significant relationships were found between gender or coronary artery disease and the frequency of coronary artery anomalies. Conclusion Coronary artery anomalies and variants, which are mostly asymptomatic, represent a broad spectrum of entities that can be accurately diagnosed by coronary CT angiography.
