AIMS: Because vascular restoration therapy using bioresorbable vascular scaffolds (BRS) remains an appealing concept to restore vasoreactivity, understanding of biodegradation remains paramount during preclinical testing. METHODS AND RESULTS: Qualitative characterization of biodegradation was performed in 41 DREAMS 1G up to 3 years, while degradation kinetics were acquired in 54 DREAMS 2G implanted into porcine coronary arteries for 28, 90 and 180 days, 1 and 2 years...

BACKGROUND AND OBJECTIVE: Studies conducted across the world have reported that the rates of major adverse cardiac events (MACE) following the use of bioresorbable vascular scaffolds (BVS) are comparable to that noted with traditional drug eluting stents (DES). However, there is limited data on the immediate and medium-term clinical outcomes following the use of the Absorb BVS (Abbott Vascular, Santa Clara, SA) in the Indian context. This study was conducted to determine real-world evidence on the immediate and medium-term clinical outcomes in all patients undergoing percutaneous coronary intervention (PCI) with the Absorb BVS...

PURPOSE OF REVIEW: In-stent restenosis (ISR) is a complex disease process that became apparent shortly after the introduction of stents into clinical practice. This review seeks to define in-stent restenosis (ISR) as well as to summarize the major treatment options that have been developed and studied over the past two decades. RECENT FINDINGS: Recent developments in drug-coated balloons and bioresorbable vascular scaffolds have added new potential treatments for ISR...

BACKGROUND: The bioresorbable vascular scaffold (BVS) technology may be an appealing option in ST-segment elevation myocardial infarction (STEMI) patients. However, the available evidence on its use in this challenging subset is limited. METHODS: Registro Absorb Italiano (RAI) is a multicenter, prospective registry that aims to assess BVS performance through a 5-year follow-up of all consecutive patients who undergone at least 1 successful BVS implantation. As a part of it, a subgroup analysis in STEMI patients was performed and the outcomes of this cohort compared to the remaining population (defined as "non-STEMI") are reported here...

REVIEW

Bioresorbable scaffolds (BRS) were introduced in clinical practice to overcome the long-term limitations of newer-generation drug-eluting stents. Despite some initial promising results of the Absorb BRS, safety concerns have led to the discontinuation of the commercialization of this device. Several retrospective studies have assessed the impact of the so-called Pre-dilation, Sizing and Post-dilation (PSP) technique concluding that an optimal PSP technique can improve clinical outcomes following BRS implantation...

OBJECTIVES: The authors sought to evaluate the safety and effectiveness of the NeoVas bioresorbable scaffold (BRS) compared with metallic drug-eluting stents. BACKGROUND: BRS have the potential to improve very late outcomes compared with metallic drug-eluting stents, but some BRS have been associated with increased rates of device thrombosis before complete bioresorption. NeoVas is a new poly-l-lactic acid BRS that elutes sirolimus from a poly-D, l-lactide coating...

Aims: As a sine qua non for arterial wall physiology, local hemodynamic forces such as endothelial shear stress (ESS) may influence long-term vessel changes as bioabsorbable scaffolds dissolve. The aim of this study was to perform serial computational fluid dynamic (CFD) simulations to examine immediate and long-term haemodynamic and vascular changes following bioresorbable scaffold placement. Methods and results: Coronary arterial models with long-term serial assessment (baseline and 5 years) were reconstructed through fusion of intravascular optical coherence tomography and angiography...

BACKGROUND: Whether polymeric bioresorbable vascular scaffolds (BVS) implantation with transradial approach is feasible and safe is unknown. We compared the feasibility and safety of the transradial approach for BVS delivery with metallic drug-eluting stents (DES). METHODS: We identified 118 consecutive patients who underwent BVS implantation and we compared 30-days and 1-year results with 118 matched patients with DES. Patients were matched for age, sex, risk factors and clinical indication...

INTRODUCTION: Little is reported on surgical outcomes of SERI Surgical Scaffold, a bioresorbable silk-derived surgical scaffold, developed to provide soft-tissue support and repair, in implant/expander breast reconstruction. METHODS: A retrospective chart study was conducted of all patients who underwent direct-to-implant reconstruction with a SERI surgical scaffold after skin-sparing mastectomy, recording surgical characteristics, perioperative complications and reoperations...

BACKGROUND: Tremendous efforts have been made to establish the concept of vascular restoration therapy with a fully bioresorbable scaffold for coronary artery disease. With an improved scaffold design and technologies, the novel NeoVas scaffold has shown promising clinical performance at 6 months follow-up. OBJECTIVE: The aim of this study was to investigate the 1 year clinical outcomes and multislice computed tomography (MSCT) angiographic results after implantation of the NeoVas scaffold in patients with single de novo coronary artery lesions...

Coronary lesions at bifurcation sites are frequent and still remain a challenging subset for the interventional cardiologist. Although in the last years the provisional stenting technique has shown more consistent results, coronary bifurcation interventions still share a worse procedural success rate and increased rates of mid- and long-term cardiac events. Most of the dedicated devices proposed in the last few years have failed to show improved results when compared with standard devices. The broader use of imaging techniques, such as intravascular ultrasound and optical coherence tomography, lead to a better understanding of the real anatomy of bifurcations and has shown to be a great tool for percutaneous coronary intervention optimization...

BACKGROUND: Evaluation of recurrent angina after percutaneous coronary interventions is challenging. Since bioresorbable vascular scaffolds (BVS) cause no artefacts in magnetic resonance imaging (MRI) due to their polylactate-based backbone, evaluation of vascular patency by MRI might allow for non-invasive assessment and triage of patients with suspected BVS failure. METHODS: Patients with polylactate-based ABSORB-BVS in proximal coronary segments were examined with 3 Tesla MRI directly (baseline) and one year after implantation...

OBJECTIVES: to compare the 1-year outcome between bioresorbable vascular scaffold (BVS), everolimus-eluting stent (EES), and drug-eluting balloon (DEB) for in-stent restenosis (ISR) treatment. BACKGROUND: BVS has been proposed as alternative for ISR treatment. To date a direct comparison between BVS and DES or DEB for ISR treatment is lacking. METHODS: We retrospectively analyzed all ISR lesions treated with BVS, DEB, and EES from January 2012 to December 2014...

The percutaneous coronary intervention has undergone rapid evolution over the last 40 years and has become one of the most widely performed medical procedures. The introduction of intracoronary stents improved the safety and efficacy of percutaneous coronary intervention. But with the advent of stenting, a new potentially fatal enemy emerged: stent thrombosis. Ever since, adjunct pharmacological therapy, stent technique and technology have been adjusted to reduce the risk of stent thrombosis. The aim of the present article is to provide an overview of past, present and future aspects of percutaneous intervention in relation to stent thrombosis...

OBJECTIVES: To identify potential underlying mechanisms of early and (very) late scaffold thrombosis (ScT) by optical coherence tomography (OCT), in a frame-by-frame analysis. BACKGROUND: The absorb scaffold is associated with an increased risk of ScT compared with metallic stents. Several potential causes of bioresorbable ScT have been identified, however the precise etiology still remains unclear. METHODS: Between February 2013 and February 2016, 13 patients presenting with definite ScT underwent OCT imaging...
