WebApr 16, 2024 · The mechanisms of DES-ISR can be biological, mechanical, or technical; its pattern is predominantly focal. Intravascular imaging can assist in defining the mechanism and selecting treatment modalities. Based on the current available evidence, intravascular imaging will help in selecting optimal approaches to treat DES restenosis [ 9 ]. WebDrug-eluting stents (DES) have revolutionized the treatment of coronary artery disease by reducing the rate of in-stent restenosis from 20-40% with bare-metal stent (BMS) to 6-8% with DES. However, with widespread use of DES, safety concerns have risen due to the observation of late stent thrombosis. WebA stent provides the mechanical capability to dilate the vessel in order to create a larger lumen, and minimize elastic recoil. Paclitaxel is incorporated into a polymer carrier matrix, coated onto the stent and delivered to the inner arterial wall so that a reduction in restenosis may be achieved by locally controlling cell replication. chibearse
