Gentle second chance: new Valve-in-Valve study for failing heart valves
NCT ID NCT07215143
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study follows about 300 patients across Europe who need a second minimally invasive heart valve replacement (TAVI-in-TAVI) because their first valve has worn out or is leaking. Doctors will use the Myval valve for the replacement. The study will track how well the procedure works and any complications over up to five years, using information from routine medical care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Myval transcatheter heart valve (OctaCor/OctaPRO)
- What this could lead to
- If successful, this could show that a second TAVI procedure with the Myval valve is a safe and effective alternative to repeat open-heart surgery for patients whose first valve has worn out.
- What could go wrong
- This is an observational study, not a randomized trial, so it cannot prove the Myval valve is better than other options. Results depend on routine care data, which may be incomplete. The procedure itself carries risks like any heart valve replacement.

Inclusion Criteria: * A TAVI-in-TAVI procedure with implantation of the Myval THV (Oc-taCor/OctaPRO) into a previously implanted (≥3 months) failing transcatheter heart valve of any kind is either planned, has al-ready been performed, or was attempted, based on a clinical indi-cation established by the treating heart team. * Age: 18 years or more * Informed consent has been obtained.
