New heart valve fix without open surgery shows promise in High-Risk patients

NCT ID NCT03039855

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a new device called the Tiara valve, which is implanted through a small tube in the chest to replace the leaky mitral valve without open-heart surgery. It enrolled 157 people with severe mitral regurgitation who were considered too high-risk for traditional surgery. The main goals were to see if the device could safely reduce the valve leakage and improve survival and quality of life.

What this could mean

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

Active substance

Tiara mitral valve and delivery system (a device implanted via a tube through the chest to replace the leaky heart valve)

What this could lead to

If it works, this could offer a less invasive option for people with severe mitral regurgitation who are too high-risk for open-heart surgery.

What could go wrong

This is a completed early-stage study without a control group, so results may not apply to all patients. Device implantation carries risks like bleeding, infection, or valve failure.
