Exercise heart MRI for low-flow aortic stenosis
Part of Heart & circulation clinical trials.
This trial uses a special heart MRI scan before and after exercise to study blood flow in people with a type of aortic stenosis where the heart's pumping function may be reduced. It could help doctors better understand how to treat this condition.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have severe aortic stenosis with low blood flow and a low pressure difference across the valve
- You can lie flat for about 40 minutes without moving
- You are not claustrophobic
- Your kidney function is normal (eGFR above 30)
- You have no allergy to MRI contrast dye
- You can exercise while lying on your back

This trial compares two pressure-based measurements of blood flow in the coronary arteries with a PET heart scan in people with severe aortic valve stenosis. It may help doctors choose the most accurate way to assess blood flow and guide care during valve treatment.
This study uses a special exercise MRI to see how the heart works during activity in people with a type of heart failure where the heart's pumping strength is normal. It also includes people with shortness of breath from other causes and healthy volunteers to compare results.
This trial studies how well different MRI images can assess heart valve problems—like leaking (regurgitation) or narrowing (stenosis). It may help doctors get clearer information, especially in people who may not respond well to cardiac resynchronization therapy (CRT).
This study uses a special type of MRI, called 4D flow MRI, to better understand how severe aortic stenosis (a narrowed heart valve) affects heart function. It may help doctors learn more about different types of this condition and improve future treatment.
This trial uses a special MRI scan to check how stiff the main artery (aorta) is in people with a narrowing called coarctation. It aims to understand how the stiffness affects the heart and blood vessels, which could help guide future care.
This study looks at how exercise affects people with aortic aneurysms and how the aorta's structure relates to its function. You may join if you have an aortic aneurysm and are being monitored or scheduled for surgery, or if you are a healthy person for comparison.
