Lithotripsy for under-expanded stents in calcified heart arteries
Part of Heart & circulation, Hormones & metabolism clinical trials.
This trial tests a shockwave treatment (intravascular lithotripsy) to open a stent that didn't expand fully in a heavily calcified artery. It may help patients who still have significant blockage after standard balloon inflation.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have symptoms or signs of reduced blood flow to the heart (myocardial ischemia).
- Your target artery is between 2.75 mm and 4.0 mm wide, and the narrowed area is 30 mm or shorter.
- Your stent did not expand fully, leaving a blockage greater than 20% even after high-pressure balloon inflation.
- You are willing to come back for follow-up visits and tests after the procedure.

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 study tests whether using a special camera inside the artery to guide a shockwave device (intravascular lithotripsy) can safely break up severe calcium deposits in heart arteries. If you have a tight, calcified blockage that needs treatment, this trial may offer a precise, guided approach to opening the artery.
This trial compares two treatments for heavily calcified heart artery blockages: a special balloon that uses sound waves to break up calcium (lithotripsy) versus a standard balloon. It also looks at whether using a camera inside the artery (OCT) helps guide the procedure.
This trial is testing a device called SONICURE to help open up stents that haven't expanded fully inside a heart artery. It is for people with heart disease who are having a procedure to treat a narrowed or blocked artery.
This trial tests whether a drug-coated balloon (a tiny balloon that releases medicine) works as well as a drug-coated stent (a mesh tube) for treating hard calcium deposits in heart arteries. Patients first receive a special shockwave treatment to break up the calcium.
This trial tests a special balloon that uses shock waves to crack calcium in heart arteries, making it easier to place a stent. It is for people with chest pain or signs of heart strain due to a single, severely blocked artery with dense calcium.
