Comparing two ways to treat hard calcium in heart arteries
Part of Heart & circulation clinical trials.
This trial tests two methods for breaking up heavy calcium buildup in heart arteries before placing a stent. It compares a specialized high-pressure balloon to a device that uses shockwaves.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have chest pain (angina) or have had a heart attack in the past, but not a severe type called STEMI.
- You need a stent for a new calcium blockage in your heart artery.
- The blockage is at least 70% narrow, or 50-70% with evidence of reduced blood flow.
- The calcium involves a large amount of the artery wall (at least 270 degrees) as seen on imaging.
- A regular balloon could not open the blockage enough before the test.
- You are not allergic to contrast dye, can take blood thinners, and have no active autoimmune disease.

This trial compares two techniques (orbital atherectomy and intravascular lithotripsy) to break up tough calcium deposits in the heart's arteries that can block blood flow. If you have a calcified nodule and are having a non-emergency procedure to open a blocked artery, this study may help guide which method works best.
This trial compares two ways to treat hardened (calcified) coronary arteries using a tiny rotating burr (rotational atherectomy) followed by either one of two balloon techniques to open the artery. It aims to see which method better prepares the artery for a stent, potentially improving blood flow and reducing complications.
This trial studies whether one type of balloon works better than another for treating badly calcified (hardened) coronary artery blockages. If you qualify, you would be randomly assigned to get the tested balloon treatment during your heart procedure.
This trial compares two treatments for severely calcified coronary arteries: a drug-coated balloon (DCB) and a drug-eluting stent (DES). It is for people who have already had a procedure to crack or soften the calcium (like rotational atherectomy), and whose blood flow looks good afterward.
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 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.
