Shockwave therapy may improve stent success in hardened leg arteries

This study tests whether using a special shockwave device to break up calcium before placing a stent works better than the usual balloon angioplasty in people with peripheral artery disease (PAD) and heavily calcified leg arteries. About 120 participants will be randomly assigned to one of the two approaches. The goal is to see which method leads to better blood flow and fewer complications after stent placement.
