Headband device could spot hidden shunts without needles
NCT ID NCT07414446
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a head-worn ultrasound device called SONAS that listens for bubble signals in the brain during a standard heart ultrasound. It aims to see if the device can accurately detect right-to-left shunts—abnormal connections between blood vessels—in adults with hereditary hemorrhagic telangiectasia (HHT). Participants wear the headband while getting a routine bubble echo test, and the device's readings are compared to the standard test results.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Transcranial Ultrasound Device (SONAS)
- What this could lead to
- If successful, this device could offer a simpler, non-invasive way to detect and distinguish heart vs. lung shunts, potentially reducing the need for more invasive tests.
- What could go wrong
- This is a small, early-stage study (40 participants) focused on diagnostic accuracy. The device may not prove reliable enough to replace standard methods, and results may not apply to broader populations.
