The study includes high-risk patients with heavy calcification who are often excluded from similar trials.<\/p>\n<p>The 30-day results show promising outcomes, with low Major Adverse Limb Events (MALEs) and no mortality. A majority of patients experienced a substantial reduction in stenosis, with more than 90% achieving less than 50% residual stenosis and approximately 75% reaching less than 30% residual stenosis\u2014all with a low stent rate (less than 5%) and low angiographic complications (1.0% at Final). Additionally, early wound healing signals were observed, and a mean improvement in Vascular Quality of Life scores within 30 days. The investigators are particularly excited about the upcoming six-month and one-year data, which will provide more insight into long-term wound healing and vessel patency.<\/p>\n<div class=\"video\"><iframe title=\"YouTube video player\" data-src=\"https:\/\/www.youtube.com\/embed\/FsYQEOxKT0E?si=yA0VcXtBXpAgivZE\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" data-load-mode=\"1\"><\/iframe><\/div>\n<div><\/div>\n<div><a class=\"btn--primary\" href=\"https:\/\/shockwavemedical.com\/en-eu\/clinical-evidence\/btk-ii\/\">DISRUPT BTK II Full 30-day results<\/a><\/div>\n<hr \/>\n<p><span class=\"legal_copy\">Chandra V, Lansky AJ, Sayfo S, et al.
