Aims Characterization of neointimal tissue is essential to understand the pathophysiology of in-stent restenosis (ISR) after drug eluting stent (DES) implantation. Using optical coherence tomography (OCT), we compared the morphologic characteristics of ISR between first and second generation DES. Methods and Results OCT was performed in 66 DES-ISR, defined as > 50% angiographic diameter steno...
Treating multivessel disease in the era of coated stents: introduction N umerous reports in cardiology congresses and journals deal with multivessel treatment with percutaneous transluminal coronary angioplasty (PTCA) and stenting. Clinical practice, however, is very different with more than 90% of all percutaneous revascularisation procedures in Europe and the USA limited to single vessel trea...
OBJECTIVES This study sought to investigate the relative safety and efficacy of bioabsorbable polymer (BP)-based biolimus-eluting stents (BES) versus durable-polymer (DP)-drug-eluting stents (DES) and bare-metal stents (BMS) by means of a network meta-analysis. BACKGROUND Studies have suggested that BP-BES might reduce the risk of stent thrombosis (ST) and late adverse outcomes compared with ...
Background—Guidelines recommend that noncardiac surgery be delayed until 30 to 45 days after bare-metal stent implantation and 1 year after drug-eluting stent implantation. Methods and Results—We used linked registry data and population-based administrative health care databases to conduct a cohort study of 8116 patients (Ն40 years of age) who underwent major elective noncardiac surgery in Onta...
BACKGROUND Drug-eluting stents have been used in daily practice since 2002, with the clear advantages of reducing the risk of target vessel revascularization and an impressive reduction in restenosis rate by 50%-70%. However, the occurrence of a late thrombosis can compromise long-term results, particularly if the risks of this event were sustained. In this context, a registry of clinical cases...
BACKGROUND Percutaneous coronary intervention (PCI) using drug-eluting stents significantly reduces the risk of restenosis in the general population. However, in patients on hemodialysis, adverse cardiac events are frequently seen even if treated with drug-eluting stents. Recent studies suggest that C-reactive protein (CRP) reflects vascular wall inflammation and can predict adverse cardiac eve...
Background—Polymer formulation may affect the efficacy of drug-eluting stents. Resolute, Endeavor, and ZoMaxx are zotarolimus-eluting stents with different stent platforms and different polymer coatings and have been tested in clinical trials. The aim of this analysis was to compare the efficacy of zotarolimus-eluting stents with different polymers. Methods and Results—Data were obtained from t...
Despite impressive advances in stent technology, unprotected left main coronary artery (LMCA) disease requiring revascularization remains the province of the surgeon at most institutions. In a 2007 editorial, we summarized the evolution of percutaneous coronary intervention (PCI) for LMCA disease, concluding that given the available evidence at that time, coronary artery bypass graft surgery (C...
