BACKGROUND: The right radial artery has gained popularity as the preferred access site for coronary angiography. To save time and limit the radiation exposure of operators and patients, newly designed catheters can be used to access both the right and left coronary arteries. The aim of this study was to compare operator radiation exposure between single-catheter (SCA) and two-catheter approaches (TCA). METHODS: In all, 256 patients undergoing diagnostic coronary angiography via the right radial artery in a high-volume medical center were randomized to either the SCA or TCA group...

The purpose of this study was to compare diffusion tensor metrics in normal age-matched neonates with survivors of hypoxic-ischemic encephalopathy (HIE) and extracorporeal membrane oxygenation (ECMO). Thirty-five normal, 27 HIE, and 13 ECMO infants underwent MRI at 3 T. Neurodevelopmental assessments were performed. Fractional anisotropy (FA), axial diffusivity (AD), and radial diffusivity (RD) of the inferior fronto-occipital fasciculus, inferior longitudinal fasciculus, anterior commissure, genu corpus callosum and splenium of the corpus callosum, anterior and posterior limb of the internal capsule, superior longitudinal fasciculus, and the centrum semiovale were analyzed with tract-based spatial statistics modified for use in neonates...

PURPOSE: Shared decision-making, when physicians and patients collaborate and agree on health care decisions, is a key tenant of patient-centered care. Choice of access site for neurovascular procedures is rarely a shared decision point between physicians and patients. We present our initial evaluation of patient preference for radial over femoral access for cerebrovascular procedures. MATERIALS AND METHODS: IRB approved single-center, prospective, and consecutive survey of all patients undergoing transradial access for cerebrovascular imaging and intervention...

The present paper describes the application of a sol-gel procedure on radially elongated pillars (REPs) using tetramethoxysilane and methyltrimethoxysilane. After octadecylsilylation, the quality of the porous layered REP (PLREP) columns was evaluated by in-situ determination of migration velocities and band broadening of coumarin dyes with fluorescence microscopy in reversed-phase liquid chromatography. Based on the increase in retention due to the sol-gel process, an increase in accessible specific surface by a factor of 112 was observed...

In-stent restenosis of the renal arteries is relatively common and its management is not well studied. An 83-year-old female with bilateral renal artery stenosis and balloon angioplasty and stenting bilaterally one year ago was found to have recurrent severe elevations in the blood pressure despite medical management. Renal artery duplex showed 60-99% stenosis of the right renal artery and 20-59% stenosis of the left renal artery. A subsequent angiography of the right renal artery revealed 80% in-stent restenosis at the ostium...

BACKGROUND: Studies have shown reduction in major bleeding with trans-radial intervention (TRI) compared with trans-femoral intervention (TFI), and with use of bivalirudin compared with heparin+glycoprotein IIb/IIIa inhibitors (GPI). We compared major bleeding, mortality and the interaction between arterial access site and the anticoagulant used for PCI in Veterans. METHODS: A retrospective cohort of 1192 consecutive patients who underwent PCI at a VA hospital between 2006 and 2012 was divided into TFI-heparin (n=192), TFI-bivalirudin (n=272), TRI-heparin (n=274) and TRI-bivalirudin (n=454) groups...

OBJECTIVES: Heart failure is the leading cause of hospitalization among patients older than 65 years of age. A significant proportion of patients require heart catheterization for diagnostic, therapeutic, and prognostic purposes. To determine the feasibility and safety of full arm-arm catheterization access, we aimed to compare this approach with other established catheterization approaches. METHODS AND RESULTS: In this retrospective cohort study, a total of 493 consecutive patients with heart failure requiring right and left heart catheterization were studied and analyzed...

Bivalirudin is a reasonable choice during transradial PCI for acute MI when bleeding risk is high and clopidogrel or cangrelor is used Heparin is reasonable during transradial PCI when bleeding risk is low and high-intensity antiplatelet therapy is used Future studies are required to define the utility of post-PCI bivalirudin infusions.

Trans-ulnar access is a viable alternative approach by experienced operators when the radial and femoral arteries cannot be accessed or used to preserve the contralateral radial artery as possible vascular graft for coronary bypass surgery, hemodynamic monitoring, or shunt creation for hemodialysis. We report a challenging case of ipsilateral trans-ulnar recanalization of a chronic radial artery occlusion, which allowed us to perform a complex trans-ulnar PCI.

The study sought to evaluate the benefit of the reduction in intensity and duration of the hemostasis obtained with the transradial (TR) Band compression device on the radial artery occlusion (RAO) rate. RAO is the most frequent complication of TR access for cardiac catheterization and limits future use of this safe route. Its occurrence must be minimized. Between 2009 and 2016, 3,616 TR accesses were randomized to TR Band hemostasis during 3 consecutive protocols: CRASOC I (Compression of Radial ArterieS without Occlusion): 13 versus 10 cc of air into the TR Band and for 4 hours of continuous compression; CRASOC II: 10 cc of air for 3 hours versus 2 hours of compression; and CRASOC III: 10 cc of air for 2 hours versus 1...

Hospital-wide engagement is required to alleviate the problem of ED crowding and its associated adverse effects. To this end, the article describes a novel visualisation termed 'the ED Capacity Clock', which can be formatted using business intelligence software. This radial diagram represents ED capacity and its consumption in a format that can be understood intuitively and at a glance. The ED Capacity Clock is designed to promote common understanding and discussion between relevant hospital services and also acts as an auditing tool to monitor processes implemented to alleviate ED crowding...
