In patients with stable ischemic heart disease (SIHD) treated with DAPT after drug-eluting stent (DES) implantation, P2Y 12 inhibitor therapy with clopidogrel should be given for at least 6 months (Class I). In patients with SIHD treated with DAPT after bare-metal stent. A stent is a small mesh tube inserted into an artery to keep it open. A drug-eluting stent is coated with a slow-release medication to help prevent blood clots from forming in a stent. Blood clotting in a stent can cause a future blockage (restenosis) and may lead to a heart attack. Stents without a drug coating are called bare-metal stents Drug eluting stents (DES) have turned up as a potential solution for restenosis. DES are combination products composed of a medicinal product(s) and medical devices and since the medicinal product(s) has an ancillary function to the device they are in accordance with the Council Directive 93/42/EE Third-generation drug-eluting stents and beyond: Where were we, where are we, and where we are heading. 27th June 2018. 9558.

Recent introduction of drug-eluting stents (DES) contributes a powe rful breakthrough to PCI A drug-eluting stent (DES) is a peripheral or coronary stent (a scaffold) placed into narrowed, diseased peripheral or coronary arteries that slowly releases a drug to block cell proliferation. This prevents fibrosis that, together with clots (), could otherwise block the stented artery, a process called restenosis.The stent is usually placed within the peripheral or coronary artery by an. Initially, drug-eluting stents (DES) were compared to bare-metal stents (BMS) for efficacy. The first double-blind randomized study was the RAVEL trial, [] which compared the sirolimus-eluting CYPHER stent with its noncoated counterpart, the BX velocity stent, in 238 patients with de novo lesions less than 18 mm in length in native coronary arteries 2.5-3.5 mm in diameter

In-stent restenosis (ISR) has been a major drawback with percutaneous coronary intervention (PCI). Intervention of ISR lesions constituted 20% to 40% of all PCIs in the era of bare metal stents (BMS) .Although drug-eluting stents (DES) substantially reduced the rates of ISR compared with BMS, the expansion of indications for PCI to complex coronary lesions in high-risk patients still makes ISR. August 27, 2012 -- Three year results from the largest randomized clinical trial of drug-eluting stents ever conducted, and the only trial sufficiently powered to measure stent thrombosis, show low rates of blood clots occurring inside drug-eluting stents implanted in real-world patients. Presented this morning in Munich by Dr. William Wijns at the 2012 Annual Meeting of the European Society. savings associated with funding of Zilver paclitaxel drug-eluting stents would be $470,000 to $640,000 per year, assuming that the use of the Zilver paclitaxel drug-eluting stent was associated with a lower risk of subsequent revascularization. Conclusions Based on evidence of low to moderate quality, Zilver paclitaxel drug-eluting stents wer Percutaneous coronary intervention with implantation of drug-eluting stents (DES) has reduced the need for repeat revascularisation compared with bare-metal stents (BMS).1 However, first-generation DES with durable polymers were associated with a slightly increased risk of stent thrombosis, especially very late stent thrombosis after discontinuation of dual antiplatelet therapy.2,3 New.
