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.

Congenital heart disease (CHD) affects approximately 1% of live births, and children with CHD often fail to meet WHO physical activity guidelines. Digital interventions to promote physical activity in CHD patients are limited. This study will develop and test a 12-week digital lifestyle intervention for children (ages 8-13) and their guardians, using a Garmin Vivofit Jr. 2 wearable to continuously monitor physical activity (PA). We will assess its impact on children's moderate to vigorous intensity physical activity (MVPA), daily activity (steps per day), quality of life, nutrition, and health literacy, as well as the quality of life and health literacy of their parents.
