New balloon method may improve stent success in Rock-Hard arteries
NCT ID NCT04253171
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special balloon that uses sound waves to break up calcium (balloon lithoplasty) works better than standard balloons for preparing severely calcified coronary arteries before placing a stent. The trial involved 200 adults with stable heart disease or non-emergency heart attacks. The goal was to see if the new technique reduces procedure failures and heart-related problems within one year.
