New ultrasound dye could spot hidden heart defects

NCT ID NCT06938347

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This phase 3 trial tests a new contrast agent called ASI-02 against the standard agitated saline for detecting right-to-left shunts in the heart. About 300 adults with suspected shunts will receive both agents during an echocardiogram. The goal is to see if ASI-02 finds shunts more accurately and safely than the current method.

What this could mean

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

Active substance

ASI-02 (a contrast agent for ultrasound)

What this could lead to

If successful, ASI-02 could become a more reliable and consistent contrast agent for detecting heart defects that allow blood to bypass the lungs.

What could go wrong

This is a phase 3 trial, but the primary goal is diagnostic accuracy, not treatment. Even if ASI-02 works better than saline, it may not change patient outcomes or be widely adopted.
