This study assessed the Optical Coherence Tomography (OCT) impact on the coronary flow in ST-elevation myocardial infarction (STEMI) after bioresorbable scaffold implantation. Only few data about OCT use in STEMI are available and coronary flow before and after OCT is not well studied yet. 54 patients with OCT performed at the end of procedure from the Prague 19 trial were selected and coronary flow was evaluated as TIMI frame count (TFC) before and just after OCT. Significant increase in TIMI frame count after OCT [from 9...

Stents are vital devices to treat vascular stenosis in pediatric patients with congenital heart disease. Bioresorbable stents (BRSs) have been applied to reduce challenging complications caused by permanent metal stents. However, it remains almost a total lack of BRSs with satisfactory compression performance specifically for children with congenital heart disease, leading to importantly suboptimal effects. In this work, composite bioresorbable prototype stents with superior compression resistance were designed by braiding and annealing technology, incorporating poly (p-dioxanone) (PPDO) monofilaments and polycaprolactone (PCL) multifilament...

BACKGROUND: We hypothesise that a comprehensive optical coherence tomography (OCT)-guided implantation protocol for bioresorbable scaffolds (BRS) might improve expansion and apposition, thus translating into better clinical outcomes, particularly reducing thrombotic events. METHODS: Patients considered suitable for BRS therapy in de novo coronary lesions underwent OCT. The predominant type of plaque was classified as lipidic, fibrous or calcific, undergoing tailored plaque preparation accordingly...

Bone defect repair, especially in terms of infection, remains a big challenge in clinical therapy. To meet clinical requirements, the dual-functional strategy including antibacterial activity and strong osteogenesis effect is a promising approach in bone tissue engineering. In the present study, bioresorbable porous-structured microspheres are fabricated from amphiphilic block copolymer composed of poly(l-lactide) and poly(ethyl glycol) blocks. After being surface coated with mussel-inspired polydopamine, the microspheres are loaded with nanosilver via reduction of silver nitrate and apatite via biomineralization in sequence...

Hydrogels are a class of materials that has the property of injectability and in situ gel formation. This property of hydrogels is manipulated in this study to develop a biomimetic bioresorbable injectable system of alginate nanobeads interspersed in fibrin network. Alginate nanobeads developed by calcium cross-linking yielded a size of 200-500 nm. The alginate nanobeads fibrin hydrogel was formed using dual syringe apparatus. Characterization of the in situ injectable hydrogel was done by SEM, FTIR and Rheometer...

BACKGROUND: Diabetes is among the strongest predictors of outcome after coronary artery stenting and the incidence of negative outcomes is still high in this specific group. Data of long-term outcomes comparing diabetic patients with non-diabetic patients treated with bioresorbable scaffolds are still incomplete. This work evaluates the long-term outcomes after implantation of a coronary bioresorbable scaffold (BRS) in diabetic patients compared to non-diabetics. METHODS: Patients who received at least one Absorb BRS in the time of May 2012 to December 2014 were enrolled into this single-center registry...

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...

Considerable advances in tissue engineering and regeneration have been accomplished over the last decade. Bioceramics have been developed to repair, reconstruct, and substitute diseased parts of the body and to promote tissue healing as an alternative to metallic implants. Applications embrace hip, knee, and ligament repair and replacement, maxillofacial reconstruction and augmentation, spinal fusion, bone filler, and repair of periodontal diseases. Bioceramics are well-known for their superior wear resistance, high stiffness, resistance to oxidation, and low coefficient of friction...

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)...

BACKGROUND: Patients with diabetes mellitus (DM) have poorer outcomes after percutaneous coronary intervention than patients without diabetes. The Abluminus DES+TM drug-eluting stent (DES) features a novel technology of fusion coating of PLLA bioresorbable polymer on both the abluminal surface of the stent and exposed parts of the balloon. AIM: To evaluate the efficacy/safety profile of the Abluminus DES+ in an all-comers population with minimal exclusion criteria and with a specific focus on diabetic patients...
