Could ultrasound replace X-Rays in heart valve surgery?
NCT ID NCT07317804
First seen Jan 09, 2026 · Last updated Jun 19, 2026 · Updated 23 times
Summary
This study tests whether using only ultrasound (echocardiography) to guide a minimally invasive heart valve replacement is as effective as the standard method that combines X-ray and ultrasound. The goal is to reduce kidney injury from contrast dye and lower radiation exposure. About 212 patients aged 70+ with severe aortic stenosis will be randomly assigned to one of the two guidance methods.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Echocardiographic guidance (ultrasound) vs fluoroscopic guidance (X-ray) during TAVR procedure
What this could lead to
If successful, echo-only guidance could become a safer alternative for TAVR, reducing kidney damage and radiation exposure for patients.
What could go wrong
This is a Phase 4 trial with 212 participants, so results may not apply to all patients. Echo-only guidance may be less precise in some cases, potentially affecting valve placement.
