Abstract
Background: Intravascular lithotripsy (IVL) delivers acoustic pressure waves to modify calcium, enhance vessel compliance, and optimize stent deployment. The Disrupt CAD IV study enrolled patients with severe coronary artery calcification and demonstrated low 30-day major adverse cardiovascular events (MACE) and high procedural success following IVL with no final serious angiographic complications. To date, long-term outcomes have not been reported. This analysis evaluates 1-year outcomes of Disrupt CAD IV.
