Shockwave treatment for under-expanded stents in calcified arteries
Part of Heart & circulation clinical trials.
This trial tests a treatment called intravascular lithotripsy to help open a stent that didn't fully expand because of calcified plaque in the heart artery. If you have this problem, it may help improve blood flow and reduce chest pain.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have a blocked or narrowed heart artery that needs a stent, and the blockage is due to hardened calcium.
- You have had a previous stent that did not fully expand, or your doctor sees a high chance this will happen.
- You have stable or unstable chest pain, or you had a heart attack more than a week ago.
- You are not pregnant and do not have severe bleeding risk or recent stroke.

This trial compares two medical devices used to prepare severely calcified coronary arteries before stenting. It aims to see if one device works as well as the other, helping patients with hardened arteries receive better treatment.
This trial tests a special device that uses sound waves to crack hard calcium in heart arteries, helping a stent expand fully after it was placed too tightly. It's for people who have a calcified artery where the stent didn't open enough, even after standard balloon treatment.
This study tests a new method called coronary lithotripsy to break up severe calcium deposits in heart arteries before placing a stent. It may help people with very hard, calcified blockages that are hard to treat with standard stenting.
This registry studies how well shockwave therapy works when a previously placed heart stent does not expand well, especially when the artery is quite calcified. Your care team would use it after other tools to prepare the blockage have not worked.
This trial tests a new single-use balloon catheter that uses sound waves to break up hardened calcium in heart arteries before placing a stent. It may help people with severe calcified blockages or completely blocked arteries that are hard to treat.
This study looks at a new type of balloon that uses sound waves to break up calcium in heart arteries before placing a stent, which may improve blood flow and reduce complications.
