No-Scalpel heart valve replacement shows promise for leaky hearts

NCT ID NCT02979587

First seen Nov 01, 2025 · Last updated Jun 23, 2026 · Updated 34 times

Summary

This study is testing a new type of heart valve, called the Harmony TPV, that can be placed using a thin tube (catheter) instead of open-heart surgery. It is designed for people with congenital heart disease who have a leaky pulmonary valve. The study involves 86 participants and is checking how safe and effective the valve is over time, including how well it works after 30 days and 6 months.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Harmony Transcatheter Pulmonary Valve (a replacement heart valve made from pig tissue and metal frame, delivered via a catheter without open-heart surgery)

What this could lead to

If successful, this could provide a less invasive option for replacing leaky pulmonary valves in people with congenital heart disease, avoiding repeat open-heart surgeries.

What could go wrong

This is a post-approval study with only 86 participants, so results may not apply to everyone. Risks include device-related complications or the valve not working as well over time.
