Summary

This study tests whether a drug-coated balloon works as well as a drug-eluting stent for people with severe calcium buildup in their heart arteries. About 656 adults will first get a procedure to soften the calcium, then be randomly assigned to one of the two treatments. Researchers will track heart-related problems like heart attacks or the need for repeat procedures over one year.
