AIMS: Bioresorbable vascular scaffolds (BVS) represent a novel therapeutic option for the treatment of coronary artery diseases. The objective of this study is to evaluate the feasibility of BVS implantation in complex chronic total occlusions (CTO). METHODS AND RESULTS: The present report is a multi-centre registry evaluating results after BVS deployment in challenging CTO lesions defined as J-CTO score≥2 (difficult or very difficult). A total of 105 patients were included in the present analysis...

Familial hypercholesterolemia is an autosomal dominant disorder due to mutations in the low-density lipoprotein receptor gene, characterized by skin and tendon xanthomas, xanthelasmas, and increased risk of premature coronary artery disease. Here, we report a case of 9-year-old girl who presented with angina and dyspnoea on exertion with xanthomas and an elevated serum cholesterol and triglyceride. She had severe stenosis of the left main coronary artery (LMCA) requiring angioplasty and placement of Bioresorbable vascular scaffold (BVS)...

A 55-year-old man underwent successful percutaneous coronary intervention for the middle left circumflex artery with a 3.5 × 28-mm bioresorbable vascular scaffold (BVS). At 18 months, follow-up coronary angiography showed ectatic change with aneurysm formation over the BVS. Optical coherence tomography revealed absence of strut continuity at the aneurysm site, in the middle of the BVS. A literature review identified nine patients with intrascaffold aneurysm, including the present patient, which developed 6-32 months after BVS implantation...

Coronary artery aneurysm formation has been described in patients after the placement of first-generation drug-eluting stents (DES), but is less common with newer generation metallic stents. In contrast, coronary artery aneurysm formation may be more common with the use of bioresorbable vascular scaffolds (BVS) due to the frequent formation of evaginations in the arterial wall seen with BVS. In this article, we describe a unique case of BVS dismantling and thrombus formation leading to an acute coronary syndrome thirty-two months after initial BVS placement...

INTRODUCTION AND OBJECTIVES: Coronary restenosis after bioresorbable vascular scaffold (BVS) implantation is infrequent and little information is available on the main characteristics of these lesions. The aim of this study was to assess restenotic lesions by using optical coherence tomography (OCT). METHODS: We studied 330 patients with coronary artery disease who received 398 BVS to treat 380 lesions. These patients were clinically and angiographically evaluated at follow-up and OCT was carried out on detection of restenosis...

Although drug-eluting stents (DES) have significantly reduced the incidence and prevalence of coronary in-stent restenosis (ISR), ISR still occurs in approximately 10% of patients in real-world practice. Areas covered: The development of newer generations of DES, drug-coated balloons (DCB) and increased use of intracoronary imaging have improved our treatment options for and pathophysiologic understanding of ISR. These technological advancements have also largely supplanted older modalities for treatment of ISR, such as brachytherapy, bare metal stents, conventional and cutting balloon angioplasty, and atherectomy devices...

Bioresorbable vascular scaffold (BVS) implantation has been shown to be safe in patients with stable coronary disease, and effective against the thrombotic lesion and the in-stent restenosis (ISR) of the drug-eluting stent (DES). BVSs have the advantages of a snow racket concept, positive vessel remodeling, and better conformability compared with DES in acute coronary syndrome (ACS). We report on a young patient with ST-elevation myocardial infarction (STEMI) who presented to our emergency department arising from very late stent thrombosis (VLST) of a 2...

BACKGROUND: Data regarding long-term clinical outcomes with everolimus-eluting bioresorbable vascular scaffold (BVS) versus second-generation drug-eluting stents (DES) are scarce. METHODS: We searched online databases until October 2016 for studies comparing BVS versus DES reporting outcomes at 2 years of follow-up. We performed a meta-analysis comparing BVS with DES across the spectrum of coronary artery disease (CAD). Random effects model OR was calculated for outcomes of interest including device-oriented composite events (DOCE; defined as composite of cardiac mortality, target vessel myocardial infarction (TV-MI), and ischaemia-driven target lesion revascularisation (TLR)), all-cause mortality, definite stent thrombosis, TV-MI and TLR...

Bioresorbable scaffolds have the potential to overcome several problems associated with metallic stents. Bioresorbable poly-L-lactic acid (PLLA) scaffold implantation for the treatment of peripheral artery disease has already been reported in animal models and clinical trials; however, no studies comparing PLLA scaffolds and bare metal stents (BMSs) with regard to early vascular morphological changes, identified using intravascular ultrasound (IVUS) analysis, have been reported. In this study, PLLA scaffolds and BMSs were implanted bilaterally in iliac arteries of five miniature pigs...

Nickel is the most frequent allergen in patients with allergic contact dermatitis and nickel allergy has been associated with recurrent in-stent restenosis. However, it is often misdiagnosed because of a low suspicion threshold. It should be discarded in patients with recurrent in-stent restenosis, especially if their medical history reveals prior contact dermatitis. It is also noteworthy and rarely specified that even newer generation stents that use novel metal alloys also contain low amounts of nickel. To avoid the implantation of new stents containing this metal, when percutaneous coronary intervention is indicated, drug eluting balloons or bioresorbable vascular scaffolds associated with small doses of steroids could provide good alternatives of treatment...

Background: Bioresorbable vascular scaffolds (BVS) were developed to improve the long-term results of percutaneous coronary intervention, restoring vasomotion. Objectives: To report very late follow-up of everolimus-eluting Absorb BVS (Abbott Vascular, Santa Clara, USA) in our center. Methods: Observational retrospective study, in a single Brazilian center, from August 2011 to October 2013, including 49 patients submitted to Absorb BVS implantation...

BACKGROUND: There are only limited studies reporting clinical outcomes after bioresorbable vascular scaffold (BVS; Absorb; Abbott Vascular, Santa Clara, CA) implantation for coronary chronic total occlusions (CTO). The aim of this study was to evaluate the real-world feasibility and safety of BVS implantation for the treatment of CTO. METHODS AND RESULTS: We retrospectively evaluated CTO cases treated with BVS from a multicenter registry. The primary end point was target lesion failure defined as a composite of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization...

OBJECTIVES: This study sought to compare the 2-year outcomes between bioresorbable vascular scaffold (BVS) and everolimus-eluting metallic drug-eluting stent (EES). BACKGROUND: The occurrence of very late stent/scaffold thrombosis (VLST) of BVS beyond 1 year after implantation is an increasing concern. METHODS: We conducted a meta-analysis of 24 studies (BVS: n = 2,567 and EES: n = 19,806) reporting the 2-year outcomes of BVS and/or EES to compare the risk of BVS versus EES for stent/scaffold thrombosis (ST) and target lesion failure (TLF) in 7 comparative studies (3 randomized and 4 observational), and to estimate the pooled incidence rates of ST and TLF including additional 17 single-arm studies...

OBJECTIVE: Treatment of chronic total occlusion (CTO) with everolimus-eluting bioresorbable vascular scaffold (BVS) is safe and effective at short-term follow-up (FU). The current study investigated clinical and angiographic outcomes after treatment of CTO with BVS at >1 year. METHODS: Thirty patients who underwent successful recanalization of 35 CTOs were included in this study. Quantitative coronary angiography (QCA) was performed at median FU period of 402 days...

BACKGROUND: The study aimed to report the results from an all-comers registry of patients undergoing coronary angioplasty and treated with bioresorbable vascular scaffold (BVS). METHODS: Fifty-five consecutive patients with type B/C coronary lesions according to the AHA classification and treated with BVS were enrolled in the study. The clinical and procedural characteristics of enrolled patients were recorded. Fifty-five consecutive subjects with coronary lesions type B/C treated with everolimus eluting stent (EES) were used as control group...
