This is a review of the first 100 coronary stents implanted for the indications of PTCA restenosis, acute or threatened closure and De Novo lesions. The success rates were high and complications rates were low. Subacute stent thrombosis rates were low and stenting for De Novo lesions in > 3.0 mm arteries provide the best short and long term results. Six months restenosis rate was low. Stent ass...

Background. Several metallic intracoronary stents are currently undergoing preliminary evaluation to ascertain potential benefit as means to reduce the 30-40% incidence of restenosis after balloon angioplasty. Methods and Results. To determine the incidence and correlates of restenosis after placement of Palmaz-Schatz stents in native coronary arteries in the first group of patients selected fo...

Small vessel size (<3 mm) has been identified as an independent predictive factor of restenosis after percutaneous coronary intervention when using bare metal stents (BMS). It remains controversial whether BMS placement in small vessels has an advantage over balloon angioplasty in terms of angiographic and clinical outcomes. The advent of drug eluting stents (DES), either paclitaxel-eluting ste...

The development of stent has been a major advance in the treatment of obstructive coronary artery disease since the introduction of balloon angioplasty. Subsequently, neointimal hyperplasia within the stent leading to in-stent restenosis emerged as a major obstacle in long-term success of percutaneous coronary intervention. Recent introduction of drug-eluting stents is a major breakthrough to t...

Since its introduction in 1977, coronary angioplasty has become an established technique for the treatment of atherosclerotic coronary disease. Currently, more than 500 000 procedures are performed each year worldwide. However, two major problems remain unresolved. The first, post-angioplasty acute vessel closure, occurs in about 5% of cases. In this setting, intracoronary stenting has been ver...

oronary arteries are readily blocked by atherosclerotic plaques, eventually triggering cardiovascular events (ie, ischemic coronary heart disease and myocardial infarction) in patients. Stent implantation is one strategy often used to attenuate the progression of coronary artery atherosclerosis and decrease cardiovascular-related mortality. Stents significantly reduce the risk rate of restenosi...

INTRODUCTION AND OBJECTIVES Surgical revascularization is the treatment of choice in patients with left main coronary artery stenosis. Conventional stents are not a valid alternative because of the rate of restenosis and sudden cardiac death. Drug-eluting stents, which reduce the rate of restenosis, may represent an alternative to cardiac surgery. The objective of this study was to describe the...

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...

OBJECTIVE The purpose of this study is to investigate the results of treatment using stent-angioplasty for symptomatic middle cerebral arterial (MCA) stenosis and comparison of in-stent restenosis between drug-eluting stents (DES), bare metal coronary stents (BMS) and self-expanding stents (SES). MATERIALS AND METHODS From Jan. 2007 to June. 2012, 34 patients (mean age ± standard deviation: 6...
