BACKGROUND The intrinsic thrombogeneity of stents was the historic limitation to their usage during the early phases of stenting. The risk of stent thrombosis has been minimized by the widespread use of platelet antiaggregation. Nowadays, the risk of subacute stent thrombosis is around 1%. Thrombotic risk depends on several factors, such as type of stent, complexity of lesion, and clinical pict...

The aim of this study was to investigate the safety and efficacy biodegradable-polymer sirolimus-eluting stents (BP-SES) compared with durable-polymer everolimus-eluting (DP-EES) in patients ST-segment elevation myocardial infarction (STEMI). Primary percutaneous coronary intervention (PCI) is an effective treatment for STEMI, long-term outcomes are determined by profile newest generation drug-...
introduction: this study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. materials and methods: this interventional study was conducted on 39 patients with coronary artery lesions, in whom zotarolimus-eluting stents (n=20), paclitaxel-eluting stents (n=11) and other stents (n=8) were deployed four tim...
The introduction of intracoronary stents represented a major advance in interventional cardiology. While bare metal stents set the benchmark for improved safety over angioplasty, intimal hyperplasia and subsequent restenosis were important limitations. First-generation drug-eluting stents demonstrated significant improvements in efficacy, but not necessarily safety, and further technologic deve...
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 apposition, this is not followed by an increase in cardiac events. Despite the ar...
BACKGROUND The impact of acute stent malapposition (ASM) on long-term clinical outcomes in patients undergoing percutaneous coronary intervention is still controversial. We sought to evaluate predictors and long-term clinical outcomes of ASM. METHODS AND RESULTS ADAPT-DES (Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents) was a prospective multicenter study of 8663 patients un...
BACKGROUND Increasing rates of percutaneous coronary intervention (PCI) and decreasing rates of coronary artery bypass graft (CABG) surgery followed the introduction of drug eluting stents in Western Australia in 2002. We assessed the impact of these changes on one-year outcomes for the total population of patients undergoing coronary artery revascularisation procedures (CARP) in Western Austra...
OBJECTIVES This study sought to compare the efficacy of drug-eluting balloons (DEB) with that of everolimus-eluting stents (EES) in patients with bare-metal stents (BMS) in-stent restenosis (ISR). BACKGROUND Treatment of patients with ISR remains a challenge. METHODS This was a prospective, multicenter, randomized trial comparing DEB with EES in patients with bare-metal stents (BMS) in-sten...
Drug-eluting stents are considered a breakthrough in the treatment of coronary artery disease owing to their ability to reduce rates of restenosis and the subsequent need for target lesion revascularization. The literature has limited reports of long-term results of drug-eluting stent implantation with respect to vascular integrity and coronary endothelial function. Thus, we review the currentl...
