To assess the efficacy and safety of the Xience Prime everolimus-eluting stent (EES) in long coronary lesions in a real-world population.
Coronary drug-eluting stent development has introduced new metal alloys, changes in stent architecture and bioresorbable polymers. Whether these advancements improve long-term clinical safety and efficacy has been inconsistent in prior studies.
The optimal treatment of in-stent restenosis (ISR) remains unknown. This study evaluates the efficacy and safety of a paclitaxel coated balloon compared to a 2nd generation sirolimus eluting stent in patients with ISR in bare metal stents (BMS) or drug eluting stents (DES).
It remains controversial whether coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI) should be optimized to treat coronary artery disease in patients on chronic hemodialysis (HD). Recently, further refinement of drug-eluting stents, such as the everolimus-eluting stent (EES), has led to marked development in this field. We compared long-term clinical outcomes after CABG versus PCI with EES implantation in patients on chronic HD.
The aim of this study was to provide contemporary outcome data for patients with de novo coronary disease and Medina 1,1,1 lesions who were treated with a culotte two-stent technique, and to compare the performance of two modern-generation drug-eluting stent (DES) platforms, the 3-connector XIENCE and the 2-connector SYNERGY.
Arterial injury related to stent strut is rare during stent-assisted coil embolization.
Previous studies have indicated that stent implantation could alter the vessel geometry, which may impact the neointimal healing process. Curvature is an important parameter for evaluating vessel geometry. The purpose of our study was to investigate the relationship between vessel curvature and neointimal healing after stent implantation.
Endothelial progenitor cells (EPCs) may allow accelerated and functional endothelialization of stents, theoretically reducing late stent complications as well reducing the duration of DAPT. In a pilot study of 193 patients at high risk of target vessel failure (TVF), the Genous EPC capturing stent (ESC) and TAXUS Liberté paclitaxel-eluting second-generation stent (PES) were similar at 5-years. Events rates appear higher for ESC within the first-year followed by higher rate of complications for PES during y...
To evaluate the effectiveness of micro-clamping stent-retriever thrombectomy (MSRT) in acute ischemic stroke patients with intracranial large vessel embolism (ILVE), and compare the same with conventional stent-retriever thrombectomy (CSRT).
Drug-eluting stent (DES) strut fracture (SF) is associated with higher incidence of In-stent restenosis (ISR)-return of blockage in a diseased artery post stenting-than seen with bare metal stents (BMS). We hypothesize that concomitance of drug and SF leads to greater neointimal response.
In this substudy of the SORT OUT VII trial, the clinical outcomes among patient with diabetes mellitus treated with Orsiro sirolimus-eluting stent (O-SES; Biotronik, Bülach, Switzerland) or Nobori biolimus-eluting stent (N-BES; Terumo, Tokyo, Japan) were compared.
The MASTER study was designed to compare performance of a new biode-gradable polymer sirolimus-eluting stent (BP-SES) with a bare-metal stent (BMS) in patients with ST-segment elevation myocardial infarction (STEMI).
Antithrombotic management after percutaneous coronary intervention is based on dual antiplatelet therapy (DAPT), that has unequivocally shown to reduce the risk of recurrent ischemic events at cost of an important risk of bleeding. In order to balance ischemic and bleeding risks, DAPT duration should be based on patients and lesions features as well as stent type. Based on these considerations, patients at high bleeding risk (HBR) undergoing PCI represent a challenging subgroup. The Synergy stent (Boston Sc...
Stent implantation at a highly curved artery has always been a challenge, considering the relatively high chance of in-stent restenosis (ISR) caused by severe straightening effect and high strain energy over the vessel wall. In this paper, a novel optimization based design method was proposed to manipulate the deformation behavior of the common ring-and-link stent. By changing the location of the connection point between rings and links, traditional ring-and-link structure was modified to achiever tunable P...
As opposed to an endoluminal stent-graft, a multilayer stent (MS) consists of a porous mesh, which allows for the possibility of treating pararenal aortic aneurysms (PRAAs) that involve a significant branch vessel. However, the choice of the density of the MS plays a vital role in isolating the aneurysm and allowing unobstructed blood flow in the branch vessel.
Stent retrievers are recognized as the most effective devices for intracranial thrombectomy. Although highly effective, such devices fail in clot removal when the brain vessel occlusion is due to organized, firm clots. The mechanism of failure is that during the retrieval, devices remain compressed by the organized clot and slide between it and the vessel wall without any removal effect. The aim of the current study is to present the preclinical evaluation of the Neva™ device, a novel stent retriever desi...
Stent retrievers have revolutionized endovascular treatment of acute ischemic stroke (AIS). Animal studies showed that mechanical thrombectomy (MT) may cause endothelial injury and intimal layer edema. Using transcranial color-coded duplex-sonography (TCCS) we observed postprocedural hemodynamic changes in the treated vessel.
Incidence of Nellix stent migration is uncommon despite absence of a proximal fixation mechanism. We present a case of intraoperative Nellix stent migration to highlight the potential complications. Our patient had renal artery occlusion and threatened limb stent perfusion as a result of intraoperative stent migration, with resultant prolapse of the Nellix endobag. We also present a successful salvage procedure to deploy an additional stent to restore limb stent flow.
Use of a BRS either in clinical practice or in the setting of an acute myocardial infarction (MI) is controversial. Despite an overall high rate of thrombosis, vascular healing response following BRS implantation tend to superiority as compared to metallic drug-eluting stent in ST-segment elevation myocardial infarction (STEMI) patients. We sought to compare the in-stent/scaffold vasomotion between metallic bioresorbable scaffold (BRS) and sirolimus eluting stent (SES) at 12-month angiographic follow-up in ...
The aim of this study was to investigate whether the underlying plaque type affects the neointimal coverage after drug-eluting stent implantation.
Perforated duodenal ulcers can be treated with a covered stent. Stent migration is a severe complication, sometimes requiring surgery. Pyloric physiology during stent treatment has not been studied and mechanisms for migration are unknown. The aim of this study was to investigate the pyloric response to distention, mimicking stent treatment, using the EndoFLIP.
The KBI (kissing balloon inflation) technique is considered the default strategy for the two-stent approach in real world practice. Studies comparing KBI and No-KBI in patients undergoing the one-stent approach have reported conflicting results. The meta-analysis was performed to compare the clinical outcomes of the KBI strategy and the No-KBI strategy for coronary bifurcation lesions in the one-stent approach. Five randomized studies were included, and a total of 1264 patients were involved in the meta-ana...
Stent technology has rapidly evolved since the first stainless steel bare metal stents with substantial developments in scaffolding, polymer, drug choice, drug delivery, and elution mechanisms. Most recently, there has been the evolution of bioabsorbable vascular scaffolds, potentially eliminating the need for long-term foreign object retention. These rapid developments have led to an ever-expanding selection of new stents, making the choice of which to use in which patient challenging. Operators must balan...
It is unclear whether the obesity paradox is still apparent in the new-generation drug-eluting stent (DES) era. Therefore, we assessed the impact of body mass index (BMI) on clinical outcome after percutaneous coronary intervention (PCI) with new-generation DESs.
