BACKGROUND: To eliminate some of the potential late limitations of permanent metallic stents, the bioresorbable coronary stents or 'bioresorbable vascular scaffolds' (BVS) have been developed. METHODS: We reviewed all currently available clinical data on BVS implantation. RESULTS: Since the 2015 position statement on the appropriateness of BVS in percutaneous coronary interventions, several large randomised trials have been presented. These have demonstrated that achieving adequate 1 and 2 year outcomes with these first-generation BVS is not straightforward...

We aimed to investigate the safety and efficacy of XINSORB bioresorbable sirolimus-eluting scaffold in porcine model. XINSORB scaffolds and metallic Firebird2™ stents were randomly implanted into minipigs' coronary arteries. Angiography, optical coherent tomography (OCT) and histopathological analyses were performed at post-procedure and 14-, 28-, 90-, 180-day follow-up. Thirty-two minipigs were enrolled. Eight XINSORB scaffolds and 8 Firebird2 stents were examined at each time point. Quantitative coronary angiography showed that in-scaffold late luminal loss (LLL) of XINSORB scaffold was 0...

A 48-year-old woman was admitted with 15-mo history of abdominal pain, diarrhea and hematochezia, and 5-mo history of defecation difficulty. She had been successively admitted to nine hospitals, with an initial diagnosis of inflammatory bowel disease with stenotic sigmoid colon. Findings from computed tomography virtual colonoscopy, radiography with meglumine diatrizoate, endoscopic balloon dilatation, metallic stent implantation and later overall colonoscopy, coupled with the newfound knowledge of compound Qingdai pill-taking, led to a subsequent diagnosis of ischemic or toxic bowel disease with sigmoid colon stenosis...

We investigated the relationship between the neutrophil-lymphocyte ratio (NLR) and in-stent restenosis (ISR) in patients with femoropopliteal chronic total occlusions (CTOs). The study enrolled 180 patients who had undergone successful stenting treatment for femoropopliteal CTO. Patients with ISR were subsequently classified into 2 groups: early-ISR (within 1 year) and late-ISR (after 1 year). The clinical characteristics, angiographic data, and follow-up data were recorded. The baseline NLR was significantly higher in the early-ISR group than that in the non-ISR group [3...

Type 2 diabetes correlates with clinical events after the implantation of a second-generation drug-eluting stent (DES). The rate and prognostic value of stent fracture (SF) in patients with diabetes who underwent DES implantation remain unknown. A total of 1160 patients with- and 2251 without- diabetes, who underwent surveillance angiography at 1 year after DES implantation between June 2004 and August 2014, were prospectively studied. The primary endpoints included the incidence of SF and a composite major adverse cardiac event [MACE, including myocardial infarction (MI), cardiac death, and target-vessel revascularization (TVR)] at 1-year follow-up and at the end of follow-up for overall patients, and target lesion failure [TLF, including cardiac death, target vessel myocardial infarction (TVMI) and target lesion revascularization (TLR)] at the end of study for SF patients...

BACKGROUND: Radiolabeled RGD peptides detect αvβ3 integrin expression associated with angiogenesis and extracellular matrix remodeling after myocardial infarction. We studied whether cardiac positron emission tomography (PET) with [(68)Ga]NODAGA-RGD detects increased αvβ3 integrin expression after induction of flow-limiting coronary stenosis in pigs, and whether αvβ3 integrin is expressed in viable ischemic or injured myocardium. METHODS: We studied 8 Finnish landrace pigs 13 ± 4 days after percutaneous implantation of a bottleneck stent in the proximal left anterior descending coronary artery...

BACKGROUND: Stent fracture (SF) and peri-stent contrast staining (PSS) after sirolimus-eluting stent implantation are reported to be risk factors of adverse events. However, the effect of these after everolimus-eluting stent (EES) implantation on long-term outcomes remains unclear.Methods and Results:The study sample comprised 636 patients (1,081 lesions) undergoing EES implantation in 2010 and follow-up angiography within 1 year. The 5-year cumulative rates of target lesion revascularization (TLR) and major adverse cardiac events (MACE: a combination of all-cause death, myocardial infarction, and TLR) were compared between patients with and without SF or PSS...

BACKGROUND: Drug eluting stents reduce the risk of in-stent restenosis but delay healing of the vascular wall. Recent data on late and very late stent thrombosis after drug-eluting stent (DES) implantation have raised concerns about the long-term safety. High lipophilicity of paclitaxel promotes rapid cellular uptake and prolongs its action. This makes paclitaxel a very promising candidate for local drug therapy intended to inhibit the proliferative and migratory processes involved in restenosis following PCI...

Coronary plaque rupture is the most common cause of acute coronary syndrome. However, the timely biomarker-based diagnosis of plaque rupture remains a major unmet clinical challenge. Balloon dilatation and stent implantation during percutaneous coronary intervention (PCI) could cause plaque injury and rupture. Here we aimed to assess the possibility of circulating microRNAs (miRNAs) as biomarkers of acute coronary plaque rupture by virtue of the natural model of PCI-induced plaque rupture. Stable coronary artery disease patients underwent PCI with single stent implantation were recruited and a three-phase approach was conducted in the present study: (i) profiling of plasma miRNAs in a group of patients before (0 h) and after balloon dilatation for 1 h (1 h vs...

OBJECTIVES: To report adverse event rates after rotational atherectomy (RA) with contemporary drug-eluting stent (DES) implantation and compare RA to cutting balloon (CB) angioplasty and balloon-only angioplasty (BA) in the all-comers ADAPT-DES trial. BACKGROUND: Percutaneous coronary intervention (PCI) of calcified lesions is increasingly common and is associated with a high risk of adverse events. RA can ablate calcified plaque and facilitate stent delivery; however, in conjunction with first-generation DES, RA was not superior to BA alone in regard to adverse events...

AIMS: Self-expanding (SE) valves are characterized with long stent frame design and the radial force of the device exists both in the inflow and outflow level. Therefore, we hypothesized that device success of SE-valves may be influenced by ascending aortic dimensions (AAD). The aim of this study was to determine the influence of AAD on acute device success rates following SE transcatheter aortic valve replacement (TAVR). METHODS & RESULTS: In 4 centers in the United States and Asia, 214 consecutive patients underwent SE-TAVR...

Endovascular redo aortic operations are a challenging undertaking. Techniques for treatment date almost as far back as the original open repair itself. Risk factors for failure following aortic repair include larger AAA necks, severe neck angulation, as well as clinical variables such as age, family history, obesity and chronic obstructive pulmonary disease. The armamentarium of endovascular treatments is vast and increasing. Aside from provisional embolization of endoleaks or deferment to open repair conversion, attention should be directed toward obtaining adequate proximal and distal sealing...
