A trial of a shockwave device for calcified heart arteries
Part of Heart & circulation clinical trials.
This trial tests a new device that uses sound waves to break up calcium deposits in heart arteries before placing a stent. It is for people with severely hardened arteries that are hard to treat with standard methods.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older and are scheduled for a stent procedure for chest pain or after a heart attack with improving heart enzyme levels.
- The calcium in your artery must be severe and visible on two different x-ray views, or you must have a hard calcium lump sticking out from the artery wall.
- Your artery must be between 2.5 and 4.0 mm wide, the blockage must be 40 mm or shorter, and the calcium must be within 0.5 mm of the inner surface of the artery.
- Your heart's pumping ability must be at least 25%, and you must not have severe kidney problems or be on dialysis.
- You cannot have a pacemaker, a clot in the treated artery, an aneurysm nearby, or a chronically totally blocked artery.
- You must be able to take blood thinners for at least 6 months.

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 tests a device approach called Shockwave IVL followed by a drug-coated balloon to treat hard, calcified coronary (heart) artery blockages. It may help improve how well the artery stays open after treatment.
This trial tests two ways to treat hardened, calcified blockages in heart arteries: shockwave therapy (lithotripsy) versus balloon angioplasty. It also looks at whether using a special imaging tool (OCT) during the procedure helps doctors choose the best treatment. This could improve outcomes for people with severe calcium buildup in their arteries.
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.
This trial tests a new device that uses sound waves to soften calcium buildup in heart arteries before placing a stent. It may help people with hardened arteries get the stent placed more safely and effectively.
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.
