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...

Coronary stent restenosis rate following implantation is considerably high. The adenosine stress gated myocardial perfusion imaging (G-MPI) method has been widely used in the diagnosis, risk stratification and prognosis evaluation of coronary heart disease; however, the high cost of adenosine limits its clinical application. The aim of the present study was to investigate the efficacy of adenosine triphosphate (ATP) stress (99m)Tc-methoxyisobutylisonitrile ((99m)Tc-MIBI) G-MPI for diagnosis in-stent restenosis following coronary stent implantation...

Superior vena cava syndrome is a well-known disease entity that carries substantial rates of morbidity and mortality. Although most cases of superior vena cava syndrome are secondary to a malignant process, additional causes (such as mediastinal fibrosis, pacemaker lead implantation, or central venous catheter placement) have been reported. Multiple treatment options include percutaneous transluminal angioplasty, stent implantation, thrombolysis, mechanical thrombectomy, and venous grafting. We present a case of superior vena cava syndrome in a symptomatic 30-year-old woman who obtained complete relief of obstruction and marked symptomatic improvement through venoplasty and stenting, aided by our use of a balloon-in-balloon catheter system...

We aimed to assess the therapeutic effect of reimplantation of biliary metal stents by percutaneous transhepatic cholangial drainage (PTCD) in patients with recurrent malignant obstructive jaundice (MOJ). Furthermore, we explored the prognostic value of inflammation-based markers in these patients.We reviewed 33 cases of recurrent MOJ after implantation of biliary metal stents by PTCD, all of which underwent reimplantation of stents under digital subtraction angiography guidance. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin were compared between before and after reimplantation (1 week, 1 month, and 3 months postoperatively)...

OBJECTIVE: Efficacy and safety data on biodegradable polymer-coated biolimus-eluting stent (BP-BES) are currently limited to 5 years. We evaluated longer term (8-10 years) clinical and angiographic outcomes after BP-BES implantation. METHODS: Between 2005 and 2008, 243 patients (301 lesions) underwent BP-BES implantation. The primary clinical outcome measure was defined as any target lesion revascularisation (TLR). Absolute serial angiographic studies without any concomitant TLR within 2 years after the procedure were performed in 55 patients (65 lesions) at postprocedure, mid-term (within 1 year), late term (between 1 and 2 years) and very late term (beyond 2 years)...

In this substudy of the ADAPT-DES trial Généreux et al. compared two years outcomes according to the presence or absence of coronary artery calcification (CAC) as assessed by coronary angiography. Coronary calcification was an independent predictor of interventional treatment failure and a higher incidence of both ischemic events and bleeding. The cohort with CAC was older with a higher prevalence of risk factors and comorbidities and an increased anatomical complexity of the target lesions, explaining only in part the worse outcome of the CAC population that persisted at multivariate analysis...

OBJECTIVE: To investigate the therapeutic effect of allopurinol treatment on acute coronary syndrome and to elucidate its possible mechanism. METHODS: Patients with acute coronary syndrome (n=100) were recruited as research subjects in our hospital. The patients were randomly divided into two groups (allopurinol group, n = 50) and control group, n= 50). These two groups were treated with conventional antiplatelet, anticoagulation and anti-ischemic therapy, while allopurinol was added to allopurinol group based on conventional treatment...

Management of the frontal sinus places great demands on the otolaryngologist. Given that the fronto-ethmoidal region is susceptible to recurrent inflammation, scarring, and stenosis, maintaining long-term patency of the frontal sinus is a difficult challenge. Oral and topical anti-inflammatory therapy, post-operative stenting, and 'home-brew' drug elution have been used for the treatment of the frontal sinus with mixed success. Recently an implant has been approved for post-operative placement into the frontal recess...

OBJECTIVES: We evaluated the clinical outcomes of patients with chronic kidney disease (CKD) who underwent orbital atherectomy for severe coronary artery calcification (CAC) prior to stent implantation. BACKGROUND: Percutaneous coronary intervention (PCI) of lesions with severe CAC is associated with increased rates of adverse clinical events. Patients with CKD are at increased risk for atherosclerotic cardiovascular disease, including vascular calcification, and have worse outcomes after PCI...

We present two cases with chronic total occlusion of the saphenous vein graft in two patients with a history of previous bypass surgery with unfavorable anatomic features for recanalization of the native coronary artery. In the first case, two dedicated attempts for recanalization of chronic total occlusion of the native artery failed and in the second case there was not an adequate visualization of the native vessel beyond the occlusion point, not even by contralateral injection. Excimer laser atherectomy was used in both cases as an adjuvant therapy during recanalization of the saphenous vein graft in combination with a distal protection device in order to reduce distal embolization...

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...

Clinical outcome is generally poor when stents are implanted at right coronary artery ostial lesion (RCAos). We compared the clinical outcome between the first-generation drug-eluting stent (first DES) and second-generation drug-eluting stent (second DES) used for RCAos. Consecutive 88 patients who underwent percutaneous coronary interventions of de novo RCAos using the first DES (33 patients) or second DES (55 patients) were analyzed. The incidence of major adverse cardiac events (MACE) defined as the composite of cardiac death, myocardial infarction attributed to right coronary artery, and target lesion revascularization within 2...
