Analysis of coronary artery anomalies and variants in cardiac risk groups through coronary computed tomography angiography

Abstract

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.
