Test heart blood-flow measurements before and after TAVI
Part of Heart & circulation clinical trials.
This study checks whether special heart tests can better understand “in-between” blocked heart arteries before and after TAVI (a valve replacement done through a catheter). It may help doctors choose the safest, most accurate treatment when coronary artery disease is unclear.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re 18 years or older
- You can understand and sign the study consent before your procedure
- You have severe aortic valve narrowing causing symptoms, and your care team recommends TAVI
- Before TAVI, your CT scan of the coronary arteries exists, and it was readable (not non-diagnostic)
- On heart imaging, you have some coronary artery narrowing that looks “in question” (often about 40–90% narrowing), and tests like pressure or flow measurements are planned

This trial compares different methods to evaluate coronary artery disease in patients planning to have a transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. The goal is to find out if a less invasive approach is as safe and effective as the standard one.
This study collects extra imaging data from 40 people who are already scheduled for a routine TAVI procedure to replace a narrowed aortic heart valve. The goal is to better understand the valve's structure and function using scans.
This study tests different ways to check for blocked heart arteries in patients getting a new aortic valve through a tube in the leg. It aims to find the best approach to guide treatment.
This trial compares two approaches for replacing a tight aortic heart valve (TAVI) through a leg artery: doing it with or without a routine check of your heart's arteries (coronary angiogram). If you have severe aortic stenosis and are scheduled for TAVI, this study helps find out whether skipping the artery check is safe and effective.
This study uses a special type of PET scan (FAPI-PET) to see how the heart heals after a less invasive valve replacement procedure called TAVI. It aims to help doctors better understand the changes in heart tissue after treatment for aortic stenosis.
This study checks whether a quick bedside blood test helps guide care during a minimally invasive TAVI procedure (a new valve put in without open-heart surgery). It may improve safety and outcomes by helping the team manage bleeding-related decisions in real time.
