Artificial Intelligence based fractional flow reserve [PDF]

Cardiology Journal
Fractional flow reserve (FFR) — a physiological indicator of coronary stenosis significance — has now become a widely used parameter also in the guidance of percutaneous coronary intervention (PCI).

Agreement of Fractional Flow Reserve Estimated by Computed Tomography With Invasively Measured Fractional Flow Reserve: A Systematic Review and Meta‐Analysis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Fractional flow reserve (FFR) is the ratio of blood pressure measured distal to a stenosis and pressure proximal to a stenosis. FFR can be estimated noninvasively using computed tomography (CT) although the usefulness of this technique remains

Fractional flow reserve [PDF]

Indian Journal of Thoracic and Cardiovascular Surgery, 2018
Physiologically driven coronary revascularization has been shown to be superior in terms of better outcomes and optimum resource utilization for percutaneous interventions. However, its applicability to surgical myocardial revascularization lacks evidence base. GRAFITTI Trial aims at bridging this gap and Dr.

Fractional-Order Windkessel Boundary Conditions in a One-Dimensional Blood Flow Model for Fractional Flow Reserve (FFR) Estimation

Fractal and Fractional, 2023
Recent studies have demonstrated the benefits of using fractional derivatives to simulate a blood pressure profile. In this work we propose to combine a one-dimensional model of coronary blood flow with fractional-order Windkessel boundary conditions ...

To Explore the Influencing Factors of Pericoronary Adipose Tissue and Noninvasive Fractional Flow Reserve on the Progression of Coronary Heart Disease Based on 320-Slice Coronary CTA

Anatolian Journal of Cardiology, 2023
Background: The objective of the study was to measure pericoronal adipose tissue parameters, fractional flow reserve with coronary artery computed tomographic angiography (CTA), and difference of fractional flow reserve with coronary artery CTA, by using

Structure (Epicardial Stenosis) and Function (Microvascular Dysfunction) That Influence Coronary Fractional Flow Reserve Estimation

Applied Sciences, 2022
Background. The treatment of coronary stenosis is decided by performing high risk invasive surgery to generate the fractional flow reserve diagnostics index, a ratio of distal to proximal pressures in respect of coronary atherosclerotic plaques.

Intravascular Imaging versus Physiological Assessment versus Biomechanics—Which Is a Better Guide for Coronary Revascularization

Diagnostics, 2023
Today, coronary artery disease (CAD) continues to be a prominent cause of death worldwide. A reliable assessment of coronary stenosis represents a prerequisite for the appropriate management of CAD.

Exploring the Predictors of the Discrepancy Between Quantitative Flow Ratio and Fractional Flow Reserve Measurements

Anatolian Journal of Cardiology, 2023
Background: Quantitative flow ratio is a novel technology for the functional assessment of intermediate coronary stenoses. The authors sought to explore the influence of diabetes mellitus on the application of quantitative flow ratio and predictors of ...
