THE USE OF INSTANTANEOUS WAVE-FREE RATIO IN A REAL WORLD PRACTICE

Journal of the American College of Cardiology, 2016
The instantaneous wave-free ratio (iFR) is a coronary artery pressure index measured in the wave-free period of diastole in absence of hyperemia. We aimed to compare iFR and fractional flow reserve (FFR) in intermediate coronary artery lesions.

Comparison of resting and adenosine-free pressure indices with adenosine-induced hyperemic fractional flow reserve in intermediate coronary lesions

Indian Heart Journal, 2019
Objective: Fractional flow reserve (FFR) using adenosine has been the gold standard in the functional assessment of intermediate coronary stenoses in the catheterization laboratory.

Hydrogel‐Based 3D‐Printed Anthropomorphic Breast Phantom for Emulating Mechanical and Dielectric Properties of Mammary Tissue. Applications in Microwave Imaging

Advanced Functional Materials, EarlyView.
A 3D‐printable breast phantom is developed using patient‐derived MRI data and hydrogels that replicate the dielectric properties of healthy and cancerous tissues. Mechanical and dielectric characterization confirm its suitability for microwave imaging.

Deciphering the Photopolymerization‐Induced Nanostructures and Interface Formation for Submicrometer Additive Manufacturing

Advanced Functional Materials, EarlyView.
This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...

Borderline coronary lesion assessment with quantitative flow ratio and its relation to the instantaneous wave-free ratio

Advances in Medical Sciences, 2021
Quantitative flow ratio (QFR) is a recently developed image-based index for the assessment of borderline coronary artery disease. We sought to investigate a correlation between QFR and instantaneous wave-free ratio (iFR) for the assessment of intermediate coronary stenoses.Patients with borderline coronary lesions (40-90% by visual assessment ...

Physiological evaluation of the provisional side-branch intervention strategy for bifurcation lesions using instantaneous wave-free ratio

Indian Heart Journal, 2018
Background: The provisional side-branch intervention strategy remains the gold standard approach for repair of coronary bifurcation lesions. We performed this study to evaluate the clinical and functional outcomes of using the instantaneous wave-free ...

Hopping‐Mediated Zero‐Bias Photocharge Retention in Solution‐Processed Van Der Waals Heterostructures

Advanced Functional Materials, EarlyView.
Liquid–liquid interface assembly enables the fabrication of solution‐processed MoS2 and WSe2 centimeter‐scale, nanometer‐thick type‐II heterostructures on paper. Interfacial charge separation and hopping‐limited recombination produce rectification and persistent photocharge retention at zero bias.
