Neha Bansal, Daisuke Kobayashi, Peter P Karpawich
A 14-year-old female was referred for severe pulmonary valve insufficiency after undergoing radiofrequency ablation for a right ventricular outflow tract tachycardia that originated in the proximal pulmonary artery at 10 years of age. Clinical records indicated that ablation was guided solely by electrograms and electroanatomical mapping. Due to myocardial tissue extensions, mapping failed to identify the level of the pulmonary valve annulus, which resulted in delivery of energy on the valve proper and into the pulmonary artery...

Background: Over the course of the thrombectomy procedure, clot fragments may become dislodged and lead to downstream emboli due to manipulation of an endovascular device. The EmboTrap thrombectomy system features an inner stent channel with an outer stent trap design that may potentially reduce the risk of distal clot fragmentation during clot removal. We tested the hypothesis that distal emboli to both the same and new territory generated during mechanical thrombectomy are a function of device design...

BACKGROUND: Idiopathic intracranial hypertension (IIH) is characterized by abnormally elevated intracranial pressure (ICP) without identifiable etiology. Recently, however, a subset of patients with presumed IIH have been found with isolated internal jugular vein (IJV) stenosis in the absence of intracranial abnormalities. METHODS: Fifteen consecutive patients were screened from 46 patients suspected as IIH and were finally confirmed as isolated IJV stenosis. The stenotic IJV was corrected with stenting when a trans-stenotic mean pressure gradient (∆MPG) was equal or higher than 5...

The optimal antithrombotic regimen for patients with atrial fibrillation and ischemic heart disease remains unclear. Therefore, we aimed to compare the efficacy and safety of triple therapy (TT [an anticoagulant and 2 antiplatelet drugs]) with dual therapy (DAPT [2 antiplatelet drugs] or DT [an anticoagulant and a single antiplatelet drug]) in patients with atrial fibrillation and ischemic heart disease. We systematically searched the Cochrane Library, PubMed and Embase databases for all relevant studies up to August 2017...

A large thrombus burden is not uncommon in primary percutaneous coronary intervention, and is associated with more frequent complications. The role of intracoronary thrombolysis and glycoprotein IIb/IIIa inhibitors in the management of a large thrombus burden is discussed. The use of thromboaspiration must follow a particular logic and used with rigorous manipulations; the capacities of the protective filters are often exceeded. Stents dedicated to thrombus management can be used. Interest and limits of these stents are developed...

BACKGROUND: Tracheal and bronchial stenosis is a life-threatening condition causing difficulty in breathing and even severe respiratory distress. The silicone tracheobronchial stents were placed using the rigid bronchoscopy into the trachea of severe dyspneic patients and they exhibited symptomatic improvement as well as a rise in the saturation of oxygen. The bronchial stents were applicable to many extensive malignant airway stenosis patients, such as those with esophageal cancer, lung cancer, and laryngeal cancer...

We present novel numerical methods for Polyline-to-Point-Cloud Registration and their application to patient-specific modeling of deployed coronary artery stents from image data. Patient-specific coronary stent reconstruction is an important challenge in computational hemodynamics and relevant to the design and improvement of the prostheses. It is an invaluable tool in large-scale clinical trials that computationally investigate the effect of new generations of stents on hemodynamics and eventually tissue remodeling...

Though carotid artery stenosis is a known origin of stroke, risk assessment and treatment modality are not yet satisfactorily established. Guideline updates according to latest evidence are expected shortly. Current clinical weakness concerns in particular the identification of "at-risk" patients. Beside the symptomatic status and the degree of stenosis, further signs of unstable plaque on carotid and cerebral imaging should be considered. Moreover, medical and endovascular therapy are continuously improving...

PURPOSE: Early in-stent restenosis after stent-protected angioplasty of the carotid artery (SPAC) is an infrequent, but potentially harmful condition for patients with carotid artery disease. METHODS: In our retrospective single-center analysis of 176 patients with carotid artery stenting between 2009 and 2015, using duplex ultrasound, we detected 9 patients with high-grade carotid artery in-stent restenosis. All restenosis patients were treated with a drug-eluting balloon (DEB) to prevent recurrent neointimal hyperplasia...

OBJECTIVE: EUS-guided hepaticogastrostomy (EUS-HGS) is often indicated for advanced stage patients because it prevents the adverse events associated with EUS-HGS procedures, and provides long stent patency. EUS-guided antegrade stenting (AS) has been developed as an advanced technique. Thus, to prevent adverse events and achieve, long stent patency, EUS-AS combined with EUS-HGS (EUS-HGAS) has been reported. The aim of this study was to evaluate the technical feasibility and efficacy of EUS-HGAS in a multicenter, prospective study...

BACKGROUND AND PURPOSE: ADAPT (A Direct Aspiration First Pass Technique), involving the first-line use of large-bore distal aspiration catheter, is a new strategy in the mechanical thrombectomy of acute ischemic stroke caused by large vessel occlusion. However, its impact on reperfusion rates, clinical outcomes, and complication rates is not fully examined. METHOD: We conducted a systematic review of the literature searching multiple databases for reports on thrombectomy of acute stroke with the ADAPT technique and performed meta-analyses of clinical and radiographic outcomes...

Smooth muscle cells (SMCs) and macrophages are important cellular components involved in the development of complications following the implantation of cardiovascular devices. This leads to various disorders such as restenosis, chronic inflammation, and may ultimately result in device failure. In this study, we developed a post-implant stent co-culture model using different ratios of SMCs and macrophages seeded on to cobalt-chromium alloy. The macrophages had an increased affinity to the co-culture surfaces, which resulted in decreased SMC attachment to the alloy surfaces at the initial time point...

PURPOSE OF REVIEW: We review the evidence on the safety and efficacy of carotid angioplasty and stenting (CAS) compared to carotid endarterectomy (CEA) and also summarizes emerging technical issues. RECENT FINDINGS: Randomized trials have demonstrated a progressive decrease of periprocedural strokes after CAS. Overall, in symptomatic patients, CAS is associated with a slightly higher risk of periprocedural strokes when compared to CEA. This is especially true after the age of 70 and immediately after a presenting symptomatic event...
