Clinical Trial Summary

Stress cardiac MRI is crucial for diagnosing coronary artery disease in adults. Currently, it is mainly performed with vasodilators in specialized centers. Introducing mobile CMR units could increase accessibility, especially in rural areas, potentially reducing unnecessary invasive procedures. The objectives include demonstrating the feasibility of mobile stress perfusion CMR, detecting CAD using Regadenoson, and evaluating the image quality of GE-267 in real-world scenarios.

Description:

Stress-cardiac MRI (CMR) has a Class I indication for the clinical diagnostic workup in adult patients with suspected coronary artery disease (CAD), including those with epicardial as well as microvascular disease (Gulati M et al. 2021; Zeppenfeld et al. 2022). According to large registry data, in more than 90% of stress-CMR-exams the test was performed using a vasodilator (Adenosine/Regadenoson) at tertiary care centers. However, the use of mobile CMR-units would make this high-end diagnostic tool available to much more patients, especially in rural areas, and by this potentially decrease the rate of unnecessary invasive procedures to rule out CAD. Therefore, we define following objectives:

1. Demonstrate the easy performance of stress Perfusion CMR in a mobile setting using a short and patient/user friendly CMR-protocol. Our hypothesis is that there are no differences in performing stress CMR using a mobile setting versus a stationary setting (based on published literature).

2. Detect mycocardial perfusion defect indicating significant CAD using Regadenoson

3. Evaluate the image quality of GE-267 in a real-world setting using a quantitative score-systeme
