Heart valve scoring device trial halted after just one patient

NCT ID NCT05052684

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

Summary

This study tested a device called Leaflex™ Performer, which is threaded through a blood vessel to the heart to score and loosen calcium buildup on stiff aortic valves. It was designed for people with severe aortic stenosis who cannot have standard valve surgery or replacement. However, the trial was terminated early after enrolling only one person, so we have very little information about how well it works or its safety.

What this could mean

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

Active substance

Leaflex™ Performer (a catheter device that scores calcification in heart valve leaflets)

What this could lead to

If it worked, this device could offer a less invasive treatment option for people with severe aortic stenosis who cannot have standard valve replacement.

What could go wrong

The trial was terminated early with only 1 participant, so results are very limited. The device may not be safe or effective, and risks include stroke, valve damage, or worsening heart function.
