Recent studies have shown that drug-eluting stents with biodegradable polymer and ultrathin struts are safe and effective, including low rates of stent thrombosis. This is why researchers conducted the BIODEGRADE (Biomatrix and Orsiro Drug-Eluting Stents in Angiographic Result in Patients With Coronary Artery Disease) study, which showed the non-inferiority at 18 months of ultrathin biodegradable polymer...
The safety and efficacy of drug-coated balloons (DCB) has been established for the treatment of in-stent restenosis of conventional bare-metal stents (BMS) and drug-eluting stents (DES). Furthermore, these devices are also used to treat de novo coronary lesions, as demonstrated in the BASKET-SMALL 2—where DCBs were non-inferior to stents—and the DEBUT RCT trials—, where DCBs...
A study compared pooled data of claudication and critical ischemia patients treated with stenting vs. by-pass surgery in femoropopliteal disease. The main objective of revascularization in femoropopliteal disease is to improve the quality of life and functional capacity of claudication patients who did not respond to medical treatment, and to save the affected limb in...
Stent thrombosis (ST) is a serious complication of coronary PCI. However, its incidence across registries is low. It has been classified according to onset into acute (less than 24 hrs.), subacute (between 24 and 30 days), late (between 30 and 365 days) and very late (later than 365 days). The estimated incidence of ST is...
Endovascular therapy in femoropopliteal territory has become the standard, mainly with self-expanding stents, aimed at preventing early vascular recoil and late constrictive remodeling. Randomized studies have shown that the use of Paclitaxel drug eluting stents (DES) reduces the number of new revascularizations (even though these studies compared mostly against conventional balloons, which is why we...
The technological development of drug eluting stents has allowed us to treat increasingly complex patients, with around 10% stenosis and using more, and longer stents. This situation generates a great challenge: keep using stents or use paclitaxel coated balloons (PCB). At present, there are sirolimus drug coated balloons (SCB), but we do not have enough...
Second generation drug-eluting stents have lower frequency of thrombotic complications and in-stent restenosis. While clinical results have significantly improved, having a 2-3% annual rate of these complications within the first year after angioplasty is still worrisome. This resulted in the development of stents with struts <70 µm (ultrathin), with bioresorbable polymer and abluminal cover. Stents...
Coronary revascularization with drug-eluting stents (DES) is very frequent, especially in acute coronary syndromes, but these metallic stents are permanent foreign bodies that activate the entire inflammatory system. Using bioresorbable stents (BRS) emerged as an alternative to this challenge. Although the initial results of the ABSORB study were not as expected (probably due to a...
Percutaneous intervention of femoropopliteal lesions have been the standard strategy these past two decades. The development of drug eluting stents (DES) or drug eluting balloons (DEB) has improved patency rate compared against conventional balloon angioplasty. The ILLUMINA -a multicenter study- looked into the polymer free self-expanding stent NiTiDES, which showed at 1 year an 87%...
In CAD patients with diabetes the polymer-free amphilimus-eluting stent resulted non-inferior to the polymer-based zotarolimus-eluting Resolute Onyx. This new device, in addition to ultrathin struts, has already been found non-inferior to the Resolute Integrity in the general population at 3-year followup. Researchers believe that the new amphiphilic carrier might be especially useful in diabetic patients...
