New study: can a simple clip replace Open-Heart surgery for seniors with leaky heart valves?

NCT ID NCT05051033

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

Summary

This study compares two ways to fix a leaky mitral valve in people aged 60 and older: a less invasive procedure using a clip (TEER) versus traditional open-heart surgery. About 450 participants will be randomly assigned to one of the two treatments. The goal is to see if the clip works as well as surgery at preventing death, repeat procedures, or worsening of the leak over at least three years.

What this could mean

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

Active substance

Mitral valve repair (surgery or transcatheter clip)

What this could lead to

If TEER proves as effective as surgery, older patients could avoid open-heart surgery and recover faster while still controlling their heart valve disease.

What could go wrong

This is a mid-stage trial with 450 participants, so results may not apply to everyone. TEER might not fix the leak as well as surgery, and both procedures carry risks like infection or bleeding.
