Summary

This study compares a new shockwave technique to standard balloon or cutting methods for preparing severely calcified heart arteries before placing a stent. About 666 adults with coronary artery disease will take part. The goal is to see if shockwave reduces major heart and brain events like heart attack or stroke.
