BACKGROUND: Bioresorbable Vascular Scaffolds (BVS) were introduced to overcome some of the limitations of drug-eluting stent (DES) for PCI. Data regarding the clinical outcomes of the BVS versus DES beyond 2 years are emerging. OBJECTIVE: To study mid-term outcomes. METHODS: We searched online databases (PubMed/Medline, Embase, CENTRAL), several websites, meeting presentations and scientific session abstracts until August 8th, 2017 for studies comparing Absorb BVS with second-generation DES...

Aims The aetiology for reduced thrombogenicity of the Magmaris resorbable magnesium scaffold (RMS) when compared with the Absorb bioresorbable vascular scaffold remains unclear. We therefore investigated whether the Magmaris RMS has platelet-repelling properties by comparing its acute thrombogenicity with an equivalent stainless steel stent in an arteriovenous shunt model. Methods and Results An ex vivo porcine carotid jugular arteriovenous shunt was established and connected to Sylgard tubing containing the Magmaris RMS with sirolimus-eluting PLLA coating and an equivalent 316L stainless steel stent with sirolimus-eluting PLLA coating...

The advent of the fully bioresorbable vascular scaffold (BVS) is the latest step in a series of advancements in the design of intracoronary stents over the past few decades. The novelty of this technology is in providing temporary vessel scaffolding and local antiproliferative therapy to prevent neointimal hyperplasia after percutaneous coronary intervention followed by gradual resorption of the scaffold to restore the native vessel anatomy and physiology-a process termed vascular reparative therapy. Areas covered: The first generation of BVS has not been able to fully match the high benchmark in safety and efficacy set by contemporary metallic drug-eluting stents...

Acute coronary syndromes (ACS) may represent an intriguing clinical scenario for implantation of bioresorbable vascular scaffold (BRS). Nevertheless, the knowledge about the performance of these devices in patients with ACS is limited. Therefore, we performed a meta-analysis of clinical studies aiming to assess the safety and efficacy of everolimus-eluting-BRS versus everolimus-eluting-metallic stents (EES) in ACS patients undergoing percutaneous coronary intervention. Six studies enrolling 2,318 patients were included and analyzed for the risk of primary safety outcome (stent or scaffold thrombosis [ST/ScT]), primary efficacy outcome (target lesion revascularisation [TLR]), and secondary outcomes (myocardial infarction, cardiac death, all-cause death)...

BACKGROUND: Data regarding neoatherosclerosis after everolimus-eluting bioresorbable vascular scaffold (BVS) (ABSORB BVS Rev. 1.1, Abbott Vascular, Santa Clara, California) implantation are limited. OBJECTIVES: This study investigated the findings of neoatherosclerosis at 5 years after BVS 1.1 implantation by using multi-imaging modalities, including optical coherence tomography (OCT). METHODS: Patients included in the ABSORB EXTEND (ABSORB EXTEND Clinical Investigation) trial at Shonan Kamakura General Hospital underwent OCT at baseline after the index procedure and at 1 and 5 years...

An unexpectedly high incidence of thrombosis in patients that received the polylactic acid bioresorbable vascular scaffold (BVS) suggests a delayed/incomplete endothelial repair with this stent. The anti-platelet agent tirofiban stimulates endothelial cell migration and proliferation, mediated by VEGF production. We investigated the tirofiban effect on the migration and adhesion of endothelial cells to BVS, in vitro. We performed human umbilical endothelial cell (HUVEC) cultures in the presence of BVS. Tirofiban, similarly to VEGF, increased the ability of HUVEC to grow on the vascular scaffold, compared to unstimulated or abciximab-treated cells...

AIMS: Absorb bioresorbable vascular scaffold (Absorb BVS) specific implantation strategies have been proposed to optimize outcomes. We analyzed whether the occurrence of definite scaffold thrombosis (ScT) and target lesion revascularization (TLR) in Absorb-treated AIDA patients was influenced by scaffold implantation techniques. METHODS AND RESULTS: Absorb BVS implantation in 1074 lesions was graded according to definitions of optimal implantation based on pre-dilatation, sizing, and post-dilatation (PSP)...

Soft tissue defects resulting from injuries, tumor resection, congenital anomalies or chronic wounds pose a great challenge to reconstructive surgery. The current gold standard in therapy of such defects is the tissue transplantation in terms of free or local flaps. Unfortunately, donor site morbidity remains a considerable risk of flap surgery. Therefore, tissue engineering of autologous vascularized long term stable adipose tissue constructs could enrich the therapeutic possibilities of soft tissue defects...

Critical limb ischemia (CLI) is a terminal stage of peripheral arterial disease that, in the absence of intervention, may lead to lower extremity amputation or death. Endovascular interventions have become a first-line approach to the management of CLI and have advanced considerably within the past decade. This review summarizes the types of percutaneous devices and the techniques that are available for the management of CLI and the data supporting their use. These include devices that establish and maintain vessel patency, including percutaneous transluminal angioplasty, drug-coated balloons, bare metal stents, drug-eluting stents, bioresorbable vascular scaffolds, and atherectomy; devices that provide protection from embolization; and, cell-based therapies...

OBJECTIVES: The aim of the study was to compare the acute outcomes of Absorb bioresorbable vascular scaffolds (BVS) and second-generation drug-eluting stent (DES) implantation in routine clinical practice. There is a paucity of data regarding BVS use in a real-world patient population. METHODS: The study population comprised 40 consecutive patients who underwent percutaneous coronary intervention (PCI) with BVS implantation at a tertiary-care center in New York, New York between July and December of 2016...

BACKGROUND: In randomized clinical trials, the risk of thrombotic events with the absorb bioresorbable vascular scaffold (BVS) was significantly higher than with metallic drug-eluting stents. We evaluated predictors of scaffold thrombosis in the large-scale, multicenter German-Austrian ABSORB RegIstRy. METHODS AND RESULTS: 3178 patients with treatment of 4252 lesions using 5020 scaffolds were included. Follow-up rate at 6 months was 97.4%. Forty-five (1.42%) patients experienced definite/probable scaffold thrombosis during follow-up...

OBJECTIVES: The aim of this study was to characterize post-procedural intravascular ultrasound (IVUS) findings in the ABSORB Japan trial, specifically stratified by the size of target coronary arteries. BACKGROUND: Despite overall noninferiority confirmed in recent randomized trials comparing bioresorbable vascular scaffolds (BVS) (Absorb BVS) and cobalt-chromium everolimus-eluting metallic stents (CoCr-EES), higher event rates of Absorb BVS have been reported with suboptimal deployment, especially in small coronary arteries...

OBJECTIVES: The aim of this study was to identify independent correlates of very late scaffold thrombosis (VLST) from an analysis of consecutively treated patients from 15 multicenter studies. BACKGROUND: Recent analyses suggest an increased risk for VLST with the Absorb Bioresorbable Vascular Scaffold compared with drug-eluting stents, but insights as to correlates of risk are limited. METHODS: A total of 55 patients were identified with scaffold thrombosis...

Background: The purpose of this paper is to provide technology trends and information regarding market and prospects in stents used for human blood vessels in Korea and the world.A stent is a medical device in the form of a cylindrical metal net used to normalize flow when blood or other bodily fluids such as biliary fluids are obstructed in blood vessels, gastrointestinal tracts, etc. by inserting the stent into a narrowed or clogged area. Stents are classified into vascular and non-vascular stents...
