New heart valve device could spare High-Risk patients from Open-Heart surgery
NCT ID NCT03230747
First seen Jul 17, 2026 · Last updated Jul 17, 2026
Summary
This trial tests a new device called the Edwards SAPIEN M3 System for people with severe mitral regurgitation, a condition where a heart valve leaks blood backward. The device is placed using a thin tube threaded through blood vessels, avoiding open-heart surgery. The study includes 72 patients who are at high risk for surgery and aims to see if the device can be safely and correctly implanted to reduce the leak.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a device called the Edwards SAPIEN M3 System, which includes a replacement valve and a dock to hold it in place
- What this could lead to
- If successful, this could offer a less invasive treatment option for people with severe mitral regurgitation who are too high-risk for surgery.
- What could go wrong
- This is an early feasibility study with only 72 participants, so the device may not work as intended or could cause complications like improper placement or emergency surgery.
