Sound waves smash heart artery calcium in new french study
NCT ID NCT05113407
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tracks 1000 patients in France who receive a special device that uses sound waves to crack calcium deposits in heart arteries before placing a stent. The goal is to see if the device is safe and works well in everyday practice. Researchers will check for heart-related problems like death, heart attack, or need for another procedure one year later.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Shockwave Medical C2 Coronary Lithotripsy System (a device that uses sound waves to break up calcium in heart arteries before placing a stent)
What this could lead to
If successful, this could show that the Shockwave C2 system is a safe and effective way to treat hardened heart arteries, potentially improving outcomes for patients with calcified blockages.
What could go wrong
This is an observational study, not a controlled trial, so results may be less definitive. The device may not work for all patients, and risks include heart attack, need for repeat procedures, or death.
