Impact of coronary revascularization on clinical outcomes in vessels with discordant results of fractional flow reserve and resting full-cycle ratio. [PDF]

Heart Vessels
Fractional flow reserve (FFR) is an invasive standard, and resting full-cycle ratio (RFR), a non-hyperemic pressure ratio, is an alternative to FFR for evaluating the functional severity of coronary stenosis.

Comparison of Resting Full-Cycle Ratio and Fractional Flow Reserve in a German Real-World Cohort

Frontiers in Cardiovascular Medicine, 2021
Objective: The aim of this study was to evaluate non-hyperemic resting pressure ratios (NHPRs), especially the novel “resting full-cycle ratio” (RFR; lowest pressure distal to the stenosis/aortic pressure during the entire cardiac cycle), compared to the

Agreement Between Invasive Wire-Based and Angiography-Based Vessel Fractional Flow Reserve Assessment on Intermediate Coronary Stenoses

Frontiers in Cardiovascular Medicine, 2021
Background: Angiography-based functional assessment of coronary stenoses emerges as a novel approach to assess coronary physiology. We sought to investigate the agreement between invasive coronary wire-based fractional flow reserve (FFR), resting full ...

Anatomical Assessment vs. Pullback REsting full-cycle rAtio (RFR) Measurement for Evaluation of Focal and Diffuse CoronarY Disease [PDF]

, 2021
Background: The morphology and functional severity of coronary stenosis show poor correlation. However, in clinical practice, the visual assessment of the invasive coronary angiography is still the most common means for evaluating coronary disease. The fractional flow reserve (FFR), the coronary flow reserve (CFR), and the resting full-cycle ratio (RFR)

Diagnostic performance of quantitative flow ratio versus fractional flow reserve and resting full-cycle ratio in intermediate coronary lesions.

, 2022
20.500.12530/87907Quantitative flow ratio (QFR) is a novel angiography-derived index aimed to assess the functional relevance of coronary stenoses without pressure wires and adenosine. Good diagnostic yield with the hyperemic fractional flow reserve (FFR)

Influence of sex on the functional assessment of myocardial ischemia [PDF]

, 2023
Background: Fractional flow reserve (FFR) and non-hyperemic resting pressure ratios, such as instantaneous wave-free ratio (iFR) and resting full-cycle ratio (RFR), are recommended for evaluating the significance of angiographically intermediate ...

TCT-626 Correlation Between Fractional Flow Reserve and Resting Full-Cycle Ratio (RFR) in the Assessment of the Clinical Significance of Borderline Stenosis in Patient With Stable Coronary Artery Disease

Journal of the American College of Cardiology, 2019
Resting full-cycle Ratio (RFR) is a novel nonhyperemic index to measure the severity of coronary artery stenosis, which was shown to correlate well with the instantaneous wave-free ratio (iFR). Our aim was to assess the correlation between RFR and fractional flow reserve (FFR) in the assessment ...

The impact of coronary microvascular dysfunction on the discordance between fractional flow reserve and resting full-cycle ratio in patients with chronic coronary syndrome

, 2022
BACKGROUND: Resting full-cycle ratio (RFR) is an alternative to fractional flow reserve (FFR) for the evaluation of borderline coronary artery lesions.
