Summary

This study tests two ways to break up heavy calcium buildup in heart arteries before placing a stent: a super high-pressure balloon versus a special shockwave balloon (lithotripsy). About 78 adults with severe coronary artery disease will be randomly assigned to one method. The goal is to see which technique allows the stent to expand more fully, which may lower the risk of future heart problems.
