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 ...

Minerva Cardiology and Angiology, 2023 Coronary flow reserve (CFR) has an emerging role to predict outcome in patients with and without flow-limiting stenoses. However, the role of its surrogate pressure bounded-CFR (Pb-CFR) is controversial. We investigated the usefulness of combined use of fractional flow reserve (FFR) and Pb-CFR to predict outcomes.This is a sub-study of the PROPHET-FFR ...

Clinical Impact of Adherence to Fractional Flow Reserve Guidance in Acute Coronary Syndrome. [PDF]
Catheter Cardiovasc IntervABSTRACT Background Fractional flow reserve (FFR) is established to guide revascularization in stable coronary disease and non‐culprit lesions in acute coronary syndromes (ACS). However, real‐world adherence to FFR guidance across the spectrum of ACS presentations, including ambiguous culprit scenarios, remains incompletely characterized.

<sup>15</sup>O-water PET-detected myocardial ischaemia and CT-derived FFR: Predicting the functional significance of anatomical stenosis. [PDF]
Clin Physiol Funct ImagingAbstract Aims Coronary artery disease (CAD) is a major cause of morbidity and mortality worldwide. While coronary computed tomography angiography (CCTA) provides anatomical assessment of coronary stenoses, its ability to determine their functional significance is limited. Computed tomography‐derived fractional flow reserve (CT‐FFR) has emerged as a non‐

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 ...

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 ...
