August 15, 2012 — Previously unreleased three-year data from the Zilver PTX randomized controlled trial of paclitaxel-eluting stents for femoropopliteal disease indicate that Cook Medical’s paclitaxel-eluting peripheral vascular stent demonstrated 83 percent freedom from TLR at 36 months in the PTX group, compared to 70.2 percent for patients treated with optimal percutaneous transluminal angioplasty and bare metal stents in the 479-patient study.
Gary M. Ansel, M.D., principal investigator of the Zilver PTX study, presented the study findings at the Japanese Association of Cardiovascular Intervention and Therapeutics (CVIT) meeting last month in Niigata, Japan.
