NCT ID NCT06991517
First seen Jan 04, 2026 · Last updated May 23, 2026 · Updated 20 times
Summary
This study tests a new way to choose the right valve size for people with a specific type of heart valve disease (bicuspid aortic stenosis) who need a valve replacement procedure called TAVR. About 290 participants will have their CT scans analyzed using the ABC Bicuspid Sizing Algorithm to guide the procedure. Researchers will check if this approach leads to better technical success right after the procedure and better valve function at 30 days.
