Microbubbles may replace needles for heart pressure checks
NCT ID NCT07416279
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether ultrasound contrast agents (microbubbles) can estimate pressure inside the heart, potentially replacing invasive catheters. Ten adults with suspected heart disease will receive a standard ultrasound with contrast while also having a catheter for comparison. The goal is to see if the microbubble signal matches catheter readings and can be calibrated to measure pressure.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
SonoVue (ultrasound contrast agent)
What this could lead to
If successful, this could lead to a non-invasive way to measure heart pressure using ultrasound, reducing the need for catheter procedures.
What could go wrong
This is a very early, small study with only 10 participants. The technique may not be accurate enough to replace catheters, and results may not apply to all patients.
