Three-Dimensional Angiographic Characteristics versus Functional Stenosis Severity in Fractional and Coronary Flow Reserve Discordance: A DEFINE FLOW Sub Study

Diagnostics, 2022
Background: Coronary angiography alone is insufficient to identify lesions associated with myocardial ischemia that may benefit from revascularization.

Ability of FFR-CT to detect the absence of hemodynamically significant lesions in patients with high-risk NSTE-ACS admitted in the emergency department with chest pain, study design and rationale

International Journal of Cardiology: Heart & Vasculature, 2020
Background: In the era of High-sensitive troponin (hs-Tn), up to 50% of patients with a mild increase of hs-Tn will finally have a normal invasive coronary angiogram.

Estimating the accuracy of a reduced‐order model for the calculation of fractional flow reserve (FFR) [PDF]

International Journal for Numerical Methods in Biomedical Engineering, 2017
AbstractImage‐based noninvasive fractional flow reserve (FFR) is an emergent approach to determine the functional relevance of coronary stenoses. The present work aimed to determine the feasibility of using a method based on coronary computed tomography angiography (CCTA) and reduced‐order models (0D‐1D) for the evaluation of coronary stenoses.

CT-FFR: Clinical Application

Majalah Kardiologi Indonesia, 2018
Invasive fractional flow reserve (FFR) is the gold standard for guiding decision making to identify patients who would benefit from revascularization. Now, computed tomography can also do that by using computational fluid dynamics to calculate fractional

Predictors of postprocedural fractional flow reserve: insights from the FFR-SEARCH study

REC: interventional cardiology (English Edition), 2021
Abstract Introduction and objectives: Patients with a low post-percutaneous coronary intervention (PCI) fractional flow reserve (FFR) are at a higher risk for future adverse cardiac events. The objective of the current study was to assess specific patient and procedural predictors of post-PCI FFR.

Comparative cost-effectiveness analyses of cardiovascular magnetic resonance and coronary angiography combined with fractional flow reserve for the diagnosis of coronary artery disease. [PDF]

, 2014
According to recent guidelines, patients with coronary artery disease (CAD) should undergo revascularization if significant myocardial ischemia is present.
