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.

Numerical simulation of the fractional flow reserve (FFR) [PDF]
Mathematical Modelling of Natural Phenomena, 2018 The fractional flow reserve (FFR) provides an efficient quantitative assessment of the severity of a coronary lesion. Our aim is to address the problem of computing non-invasive virtual fractional flow reserve (VFFR). In this paper, we present a preliminary study of the main features of flow over a stenosed coronary arterial portion, in order to ...

Fractional Flow Reserve: Comparison between Invasive and Non-invasive Methods for Calculation of FFR [PDF]
EAI Endorsed Transactions on Pervasive Health and Technology, 2018 The heart disease that affects millions of people worldwide is coronary artery disease. It is caused by a narrowing or blocking of the arteries due to plaque which restricts blood flow, and reduces the amount of oxygen to the heart. Angiogram as a tool, which represents an X-ray examination of the blood vessels in the heart, is traditional tool that ...

Improvement of Fractional Flow Reserve after Percutaneous Coronary Intervention Does Not Necessarily Indicate Increased Coronary Flow [PDF]
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 ...

Numerical and experimental investigations of Fractional Flow Reserve (FFR) in a stenosed coronary artery [PDF]
E3S Web of Conferences, 2019 The coronary artery is numerically investigated based on CFD techniques for measuring the severity of stenosis. In mild cases, medication is often preferred whereas for severe cases surgical intervention is `required but most of the cases fall in between. Thus, it poses a problem for clinicians in choosing an appropriate action.

FFR post-PCI: what we learned from the FFR-SEARCH study
REC: Interventional Cardiology (English Ed.), 2021 WHAT DO WE KNOW ABOUT FRACTIONAL FLOW RESERVE AFTER STENTING? The introduction of the concept of fractional flow reserve (FFR) in the mid 90s moved coronary physiology from experimental science to routine use at the cath lab.1-3 Added to the better ...

Coronary lesion progression as assessed by fractional flow reserve (FFR) and angiography [PDF]
EuroIntervention, 2018 The aim of this study was to explore the evolution of coronary lesions which had repeated physiologic evaluation by FFR as an endpoint, describe the clinical significance of longitudinal FFR change (ΔFFR=FFRfollow-up-FFRbaseline) and its correlation with angiographic indices, and identify predictors of FFRfollow-up.A retrospective, single-centre ...
