Choosing the right valve size for TAVI in severe aortic stenosis
Part of Heart & circulation clinical trials.
This trial is testing whether using a specific measurement of your aortic valve (the annulus perimeter) helps pick the best valve size for TAVI, a procedure to replace your narrowed aortic valve without open-heart surgery. If you have severe aortic stenosis and are already scheduled for TAVI, this study looks at which valve fits you best by using CT scans.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your heart team has decided you need a TAVI procedure.
- Your CT scan shows that the size of your aortic valve's opening (called the annulus perimeter) falls into one of these ranges: 55.5–57.5 mm, 61.0–64.5 mm, 70.5–74.0 mm, 79.5–84.0 mm, or 92.0–96.0 mm.
- You must be able to give written permission (informed consent) to join the study.

This study looks at how well doctors can predict outcomes for people with severe aortic stenosis who are getting a TAVI. It helps doctors understand what might happen after the procedure.
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 trial studies whether a new through-the-blood-vessel heart valve (TAVR) is safe and works well for people with severe aortic stenosis who are too risky for traditional surgery. If you qualify, you would be closely followed to check your symptoms and valve function over time.
This trial tests two types of replacement heart valves (self-expanding and balloon-expanding) in people who have severe aortic stenosis (tight heart valve) and an enlarged aorta (the main blood vessel from the heart). The goal is to see which valve type works better for these patients.
This study checks whether an “investigational” transcatheter aortic valve is safe and works well for people with severe, calcified aortic stenosis (a stiff, narrowed heart valve). It may help improve valve function and symptoms, but you must meet specific heart, scan, and health-status requirements.
This trial compares a “smaller valve sizing” approach versus the usual sizing method during TAVR (a catheter-based valve replacement) for people with bicuspid aortic stenosis. The study aims to see which method improves safety and outcomes for the right valve fit.
