Two ways to open a hardened heart artery
This study compares two devices that break up hard calcium in heart arteries, to see if the newer one (using shock waves) is as good as the older one (using a tiny drill). If you have a severely calcified artery, this trial may offer a gentler option.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older
- You have a narrowed heart artery that blocks at least half the blood flow and causes symptoms of reduced blood flow
- The narrowed part is hardened by calcium, confirmed by a special ultrasound test
- The artery is between 2.5 and 4.0 mm wide, and a guidewire can pass through it
- If you have other narrowed arteries, they must be treated successfully before this one
- You must be able to give written consent and not have conditions that prevent reading or signing consent

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 techniques for treating heavily calcified coronary blockages: rotational atherectomy with intravascular lithotripsy or with a special scoring balloon. It aims to see which method works better to prepare the artery for a stent.
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.
This study tests a new way to break up hard calcium deposits in heart arteries using shock waves (lithotripsy), with or without a special drill (rotational atherectomy), before placing a stent. It may help people with severely calcified blockages that are hard to treat with standard methods.
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 tests a new balloon device that uses sound waves to break up hard calcium in heart arteries. It may help people with severe calcified blockages who need a stent, including those with a completely blocked artery, as long as the blockage has not been treated before.
