Dobutamine Stress Cardiac Magnetic Resonance Imaging for Patients With Anomalous Inter-Arterial Coronary Arteries

Objective: This study aims to review the application of dobutamine stress cardiac magnetic resonance imaging (DSCMR) for patients with anomalous inter-arterial coronary arteries. Materials and Methods:Consecutive adult patients (≥18 years) with anomalous inter-arterial coronary arteries and DSCMR performed in a quaternary referral center from January 2020 to December 2024 were retrospectively reviewed.Examination details, including medication and complications, were reviewed.Radiological findings, such as wall motion abnormality, perfusion defect and late myocardial enhancement were evaluated.Post-examination management and outcomes were assessed.Results: A total of 31 patients (17 females [54.8%]; age 53.6±11.7 years) with anomalous inter-arterial coronary arteries were included.Most patients (n=25, 80.6%) had anomalous right coronary artery.There were significant differences in peak heart rate (p
