Improvement of Fractional Flow Reserve after Percutaneous Coronary Intervention Does Not Necessarily Indicate Increased Coronary Flow

European Cardiology Review, 2019
Coronary flow is expected to increase by epicardial lesion modification after successful percutaneous coronary intervention (PCI) in stable angina. According to the concept of fractional flow reserve (FFR), the improvement in FFR after PCI reflects the ...

Five‐Year Outcomes with PCI Guided by Fractional Flow Reserve

New England Journal of Medicine, 2018
BACKGROUND We hypothesized that fractional flow reserve (FFR)–guided percutaneous coronary intervention (PCI) would be superior to medical therapy as initial treatment in patients with stable coronary artery disease.

Accuracy of Computational Pressure-Fluid Dynamics applied to Coronary Angiography to Derive Fractional Flow Reserve - FLASH FFR.

Cardiovascular Research, 2020
AIMS Conventional Fractional Flow Reserve (FFR) is measured invasively using a coronary guidewire equipped with a pressure sensor. A non-invasive derived FFR would eliminate risk of coronary injury, minimize technical limitations and potentially increase

Functional Assessment of Myocardial Bridging With Conventional and Diastolic Fractional Flow Reserve: Vasodilator Versus Inotropic Provocation

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2021
Background Functional assessment of myocardial bridging (MB) remains clinically challenging because of the dynamic nature of the extravascular coronary compression with a certain degree of intraluminal coronary reduction.

Fractional Flow Reserve

JACC: Cardiovascular Interventions, 2010
Multivessel coronary artery disease is frequently encountered during cardiac catheterization of patients with acute coronary syndromes ([1,2][1]). Current guidelines from the American College of Cardiology/American Heart Association and European Society of Cardiology discourage treatment of non-

The solution supramolecular structure of α2 → 8 polysialic acid suggests a structural cause for its low immunogenicity

FEBS Letters, EarlyView.
α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...
