Early Hyperdynamic Sepsis Alters Coronary Blood Flow Regulation in Porcine Fecal Peritonitis

Frontiers in Physiology, 2021
Background: Sepsis is a common condition known to impair blood flow regulation and microcirculation, which can ultimately lead to organ dysfunction but such contribution of the coronary circulation remains to be clarified.

Prognostic Value and Risk Continuum of Noninvasive Fractional Flow Reserve Derived from Coronary CT Angiography.

Radiology, 2019
Background Coronary CT angiography with noninvasive fractional flow reserve (FFR) predicts lesion-specific ischemia when compared with invasive FFR. The longer term prognostic value of CT-derived FFR (FFRCT) is unknown.

Coagulation Matters: ATIII‐Enriched Biomolecular Corona Enhances the Hemocompatibility of PEG Nanoparticles

Advanced Healthcare Materials, EarlyView.
Engineering of a functional protein corona with a synergistic heparin‐ATIII complex significantly improves hemocompatibility of PEG nanoparticles. Through deliberate engineering of the protein corona, a 4‐fold reduction in coagulation activation (F1 + 2) without inducing adverse thromboinflammatory reactions (CD11b, C5a) is achieved without disrupting ...

First validation of myocardial flow reserve assessed by dynamic 99mTc-sestamibi CZT-SPECT camera: head to head comparison with 15O-water PET and fractional flow reserve in patients with suspected coronary artery disease. The WATERDAY study

European Journal of Nuclear Medicine and Molecular Imaging, 2018
PurposeWe assessed the feasibility of myocardial blood flow (MBF) and flow reserve (MFR) estimation using dynamic SPECT with a novel CZT camera in patients with stable CAD, in comparison with 15O–water PET and fractional flow reserve (FFR).MethodsThirty ...

Fractional flow reserve–guided coronary artery bypass grafting: Can intraoperative physiologic imaging guide decision making? [PDF]

, 2013
ObjectivesFractional flow reserve–guided coronary artery bypass grafting is emerging in cardiac surgery, in which the nature (anatomic and functional characteristics) of the target vessel epicardial coronary artery stenosis is important in graft site ...

Imaging techniques for assessment of coronary flow reserve

Monaldi Archives for Chest Disease, 2015
The assessment of coronary flow reserve (CFR) may be useful for the functional evaluation of coronary artery disease (CAD). Invasive techniques, such as intracoronary Doppler ultrasound and pressure-derived method, directly assess CFR velocity and fractional flow reserve.

Poly(hydroxy‐oxazolidone) Thermoplastic Elastomers for Safer, Greener and Customizable Blood‐Contacting Medical Devices

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 ...

Fractional flow reserve: current status [PDF]

Кардіохірургія та інтервенційна кардіологія, 2019
Since the introduction of the fractional flow reserve (FFR) into clinical practice more than 20 years ago, revascularization controlled by the measurement of physiological parameters has become routine.

Fractional flow reserve-guided percutaneous coronary intervention vs. medical therapy for patients with stable coronary lesions: meta-analysis of individual patient data

European Heart Journal, 2018
Aims To assess the effect of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) with contemporary drug-eluting stents on the composite of cardiac death or myocardial infarction (MI) vs.

Pressure-derived measurement of coronary flow reserve

Journal of the American College of Cardiology, 2005
We aimed to validate the technique of measuring the coronary flow reserve (CFR) with coronary pressure measurements against an established thermodilution technique.The CFR has traditionally required measurement of coronary blood flow velocity with the Doppler wire and, more recently, using a thermodilution technique with the coronary pressure wire ...
