Comparing two procedures for severely calcified heart arteries
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have stable heart disease, or have recently had a heart attack or unstable angina (chest pain).
- Your blocked artery must be severely calcified (hard, with calcium deposits) and narrow.
- The artery size must be within a certain range (2.25 to 4.0 mm).
- You must not have had stent placement in the same artery within the last 12 months, nor any heart bypass surgery.
- You must be able to take blood-thinning medicines (aspirin and another antiplatelet) for at least 6 months.

Other trials that look related to this one.
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 study is testing a technique to treat heavily calcified (hard) blockages in heart arteries. The goal is to see if a special way of preparing the blockage before placing a stent helps improve blood flow to the tiny blood vessels in the heart muscle.
This trial studies a heart procedure that uses a special camera to guide where to place a drug-coated stent in an artery with heavy calcium. It may help improve how well the stent fits and works for people with certain types of coronary artery blockages.
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 trial is testing whether a special heart CT scan (coronary CT angiography) can help doctors better understand and treat calcium buildup in your heart arteries. If you have a type of heart disease that might need a stent or other procedure, this study could help decide the best approach.
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.
