New tricuspid valve replacement for leaky or absent valve
This study tests a special replacement valve (an “ECM valve”) for people whose tricuspid valve is leaky or missing and needs surgery. It may help restore blood flow on the right side of the heart and is designed for certain children born with congenital heart problems.
Mobile, AlabamaAges 1–85 - NCT06557798Recruiting

Common questions
- Are there clinical trials for replacement?
- Yes. Clin2 currently lists 507 recruiting replacement studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a replacement trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a replacement trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
