Advanced Healthcare Materials, EarlyView.A poly(hydroxy‐oxazolidone) (PHOx) is synthesized from CO2‐based precursors, enabling the up‐cycling of this waste material. After synthesis, PHOx shows thermoplastic properties, and can therefore be processed by many temperature‐dependent techniques. PHOx is hemocompatible, anti‐adhesive, and biocompatible, which is demonstrated in vitro and in vivo ...

Use of the instantaneous wave-free ratio or fractional flow reserve in PCI [PDF]
, 2017 BACKGROUND: Coronary revascularization guided by fractional flow reserve (FFR) is associated with better patient outcomes after the procedure than revascularization guided by angiography alone.

Invasive physiological indices to determine the functional significance of coronary stenosis
International Journal of Cardiology: Heart & Vasculature, 2018 Physiological measurements are now commonly used to assess coronary lesions in the cardiac catheterisation laboratory, and this practice is evidence-based and supported by clinical guidelines. Fractional flow reserve is currently the gold standard method

Circulation. Cardiovascular Interventions, 2019 BACKGROUND Fractional flow reserve (FFR) is a reliable tool for the functional assessment of coronary stenoses. FFR computed tomography (CT) derived (FFRCT) has shown to be accurate, but its clinical usefulness in patients with complex coronary artery ...

73 Heritability of coronary flow reserve [PDF]
Heart, 2011 Introduction Coronary flow reserve (CRF) is the ratio of peak coronary flow during maximal coronary artery dilatation to basal coronary flow and is an important predictor of coronary microvascular function. A variety of environmental stimuli have been shown to affect CFR but little is known about the genetic component of CFR.

Coronary reserve in patients with aortic valve disease before and after successful aortic valve replacement [PDF]
, 2017 In patients with aortic valve disease and normal coronary angiograms coronary reserve was determined by the coronary sinus thermodilution technique. Three groups of patients were studied: 37 preoperative patients; 18 different patients 12.52 months after

Advanced Materials, EarlyView.This review highlights recent progress in piezoelectric materials for regenerative medicine, emphasizing their ability to convert mechanical stimuli into bioelectric signals that promote tissue repair. Key discussions cover the intrinsic piezoelectric properties of biological tissues, co‐stimulation cellular mechanisms for tissue regeneration, and ...

Assessment of coronary flow reserve in nuclear cardiology
Médecine Nucléaire, 2020 Abstract The coronary flow reserve is a quantitative parameter defined by the ratio maximal myocardial blood flow to rest myocardial blood flow, which allows to give functional information on the whole coronary arterial tree, integrating both epicardial arteries and microcirculatory.

Advanced Materials, EarlyView.A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...
