AIMS: In the drug eluting stent (DES) era, patients with acute coronary syndrome (ACS) had a higher risk of early stent thrombosis compared with stable patients. The present study evaluated whether the same is true for the bioresorbable vascular scaffold (BVS: Abbott Vascular, Santa Clara CA). METHODS AND RESULTS: We assessed the relationship between the incidence of definite/probable scaffold thrombosis (ScT) (overall ScT and early ScT) and ACS percentage with the latest publications including the most recent large randomized controlled trials...

Bioresorbable scaffolds (BRS) represent a novel horizon in interventional cardiology for the treatment of coronary artery disease. The technology was introduced to overcome limitations of current metallic drug-eluting stents such as late in-stent restenosis and permanently caging the vessel. The concept of the BRS is to provide temporal support to the vessel during healing before being degraded and resorbed by the body, promoting restoration of the vessel vasomotion. Currently, there are several BRS that are under development or already commercially available...

OBJECTIVES: To examine ischemic and bleeding outcomes in patients on triple antithrombotic therapy (TAT) compared with dual antiplatelet therapy (DAPT) after the implantation of bioresorbable scaffolds (BRS). BACKGROUND: The optimal antithrombotic regimen in patients undergoing percutaneous coronary intervention that have an indication for oral anticoagulation is unclear, in particular among those undergoing BRS implantation. METHODS: Consecutive patients of a single-center, all-comers BRS registry were included...

BACKGROUND: Limited data are currently available on the performance of everolimus eluting bioresorbable vascular scaffold (BVS) for treatment of complex coronary lesions representative of daily practice. METHODS: This is a prospective, mono-center, single-arm study, reporting data after BVS implantation in patients presenting with stable, unstable angina, or non-ST segment elevation myocardial infarction caused by de novo stenotic lesions in native coronary arteries...

BACKGROUND: Optimal strut coverage and early vascular healing are important factors to reduce the risk of stent thrombosis. Data on early vascular healing with the new bioresorbable vascular scaffolds (BVS) are lacking. Further, healing response after BVS implantation in different clinical presentation has not been fully investigated. METHODS AND RESULTS: We assessed with optical coherence tomography (OCT) the early vascular response to BVS implantation in 26 consecutive patients presenting with acute coronary syndrome (ACS) or stable angina (SA)...

To establish the accuracy of coronary computed tomography angiography (CTA) for in-scaffold quantitative evaluation with optical coherence tomography (OCT) as a reference. The translucent backbone of the bioresorbable scaffold allow us to evaluate non-invasively the coronary lumen with coronary CTA. In the ABSORB first-in-man studies, coronary CTA was shown to be feasible for quantitative luminal assessment. Nevertheless, a comparison with an intravascular modality with higher resolution has never been performed...

Percutaneous coronary revascularization strategies have gradually progressed over a period of last few decades. The advent of newer generation drug-eluting stents has significantly improved the outcomes of Percutaneous Coronary Intervention (PCI) by substantially reducing in-stent restenosis and stent thrombosis. However, vascular inflammation, restenosis, thrombosis, and neoatherosclerosis due to the permanent presence of a metallic foreign body within the artery limit their usage in complex Coronary Artery Disease (CAD)...

The Bioresorbable Vascular Scaffold (BVS, Abbott Vascular, Santa Clara, Cal, USA) is an exciting advance in percutaneous coronary intervention providing a temporary drug eluting scaffold resorbed in two to five years. We present two cases of late scaffold thrombosis associated with strut fracture during the period of resorption, at 20 and 24 months following BVS implantation. We propose luminal migration of malapposed struts following strut fracture during resorption as a potential mechanism for late scaffold thrombosis and acute coronary syndrome...

We report on two cases in which Y-shaped coronary bifurcations were treated with the use of Bioresorbable scaffolds. The first case was of a 50-year-old man with NSTEMI. Coronary angiography showed stenosis involving a Y-shaped bifurcation of proximal to mid LAD and diagonal. The lesion was wired using two 0.14 BMW guide wires, followed by serial pre-dilatation of LAD and Diagonal branch. The stent into proximal LAD was deployed first as a skirt (3.5 × 12 BVS). Stent was post-dilated. A second 2.5 × 28 BVS was deployed into diagonal branch, protruding backwards; along with a 2...

Bioresorbable vascular scaffold (BVS) is a novel technology designed to overcome the long-term limitations of permanent metallic stent implantation in percutaneous coronary intervention. However, little is known about the development of coronary aneurysms after the use of BVSs, and additional experience is needed to establish the entire spectrum of complications related to the use of these emerging materials. We hereby report an unusual case of early multiple coronary artery micro aneurysms formation after BVS implantation...

The evolution of coronary metal stents has been well known for the past three decades, but it is only in the recent past that research on bioresorbable scaffolds has gained momentum in the field of percutaneous coronary intervention. Although second-generation drug-eluting metal stents are the gold standard for the treatment of obstructive coronary artery disease, a few drawbacks exist. The development of bioresorbable scaffolds is an attempt to overcome the limitations of metal stents. This review highlights the rationale for a bioresorbable scaffold, its properties and its potential application...

AIMS: The study sought to investigate clinical and multimodality imaging assessment of a bioresorbable sirolimus-eluting scaffold (NeoVas, Lepu Medical, Beijing, China) for patients with single de novo coronary artery lesions. METHODS AND RESULTS: The NeoVas first-in-man study was a prospective, open-label study which enrolled 31 patients with single de novo lesions treated with a bioresorbable sirolimus-eluting scaffold. The primary endpoint was target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction and clinically indicated target lesion revascularisation (TLR)...
