Diagnostic Accuracy of Diastolic Fractional Flow Reserve for Functional Evaluation of Coronary Stenosis

open access: yesJACC: Asia, 2021
Background: In the resting conditions, narrowing the window of coronary pressure measurements from the whole cardiac cycle to diastole improves diagnostic performance of coronary pressure–derived physiological index. However, whether this also applies to

Validation of Quantitative Flow Ratio-Derived Virtual Angioplasty with Post-Angioplasty Fractional Flow Reserve—The QIMERA-I Study

open access: yesJournal of Cardiovascular Development and Disease, 2023
Background: Quantitative flow ratio (QFR) virtual angioplasty with pre-PCI residual QFR showed better results compared with an angiographic approach to assess post-PCI functional results.

Fractional Flow Reserve or Coronary Flow Reserve for the Assessment of Myocardial Perfusion [PDF]

open access: yesCurrent Cardiology Reports, 2018
Accumulating evidence exists for the value of coronary physiology for clinical decision-making in ischemic heart disease (IHD). The most frequently used pressure-derived index to assess stenosis severity, the fractional flow reserve (FFR), has long been considered the gold standard for this purpose, despite the fact that the FFR assesses solely ...

Extent of the difference between microcatheter and pressure wire-derived fractional flow reserve and its relation to optical coherence tomography-derived parameters

open access: yesInternational Journal of Cardiology: Heart & Vasculature, 2020
Background: Although previous studies demonstrated that microcatheter-derived fractional flow reserve (mc-FFR) tends to overestimate lesion severity compared to pressure wire-derived FFR (pw-FFR), the clinical utility of mc-FFR remains obscure.

FRACTIONAL FLOW RESERVE (FFR)

open access: yes, 2015
FFR is a form of coronary artery measurement that provides valuable information about the functional significance of coronary artery blockade. It works on a simple hemodynamic principle that the more severe the blockade, the more would be the pressure drop beyond the blockade.

Fractional Flow Reserve-guided Percutaneous Coronary Intervention: Standing the Test of Time

open access: yesCardiovascular Innovations and Applications, 2016
Percutaneous coronary intervention (PCI) improves symptoms and prognosis in ischemia-inducing, functionally significant, coronary lesions. Use of fractional flow reserve allows physicians to investigate the ischemia-inducing potential of a specific ...

3D quantitative coronary angiography based vessel FFR: clinical evidence and future perspectives

open access: yesREC: Interventional Cardiology (English Ed.), 2023
Endorsed by the current clinical practice guidelines, the indication to perform percutaneous coronary intervention (PCI) of intermediate coronary stenosis should be guided by either fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR) if ...

Impact of Poststenting Fractional Flow Reserve on Long-Term Clinical Outcomes [PDF]

open access: yesCirculation: Cardiovascular Interventions, 2021
Background: Fractional flow reserve (FFR)-guided treatment has been demonstrated to improve percutaneous coronary intervention (PCI) results. However, little is known on the long-term impact of low post-PCI FFR. Methods: This is a large prospective all comers study evaluating the ...

Simplified coronary flow reserve calculations based on three-dimensional coronary reconstruction and intracoronary pressure data

open access: yesCardiology Journal, 2023
BACKGROUND: Measurements of fractional flow reserve (FFR) and/or coronary flow reserve (CFR) are widely used for hemodynamic characterization of coronary lesions.

Cost-effectiveness of percutaneous coronary intervention in patients with stable coronary artery disease and abnormal fractional flow reserve [PDF]

open access: yes, 2013
BACKGROUND The Fractional Flow Reserve Versus Angiography for Multivessel Evaluation (FAME) 2 trial demonstrated a significant reduction in subsequent coronary revascularization among patients with stable angina and at least 1 coronary lesion with a ...
