Contemporary metallic drug-eluting stents are associated with very good 1-year outcomes but an ongoing risk of stent-related adverse events (thrombosis, myocardial infarction, restenosis) after 1 year. The pathogenesis of these very late events is likely related to the permanent presence of the metal stent frame or polymer. Bioresorbable scaffolds have been developed to provide drug delivery an...

BACKGROUND Drug-eluting stents have been seen as an attractive alternative to bare-metal stents for percutaneous coronary interventions (PCIs) because of the decreased need for revascularization. However, comparative clinical trials have shown no difference in patient outcomes, and drug-eluting stents are considerably more expensive than their bare-metal counterparts. We conducted a systematic ...

Rev Esp Cardiol 2004;57(2):99-108 99 The efficacy of drug-eluting stents measured as the late loss, percentage neointimal volume, restenosis, target lesion revascularization and major cardiac events is significantly better than that of bare metal stents. The incidence of thrombosis and aneurysms is similar. Although there is a slight increase in late malapposition, this is not followed by an in...
