Diagnostic Performance of Resting Full-Cycle Ratio in Identifying Coronary Lesions Causing Myocardial Ischaemia: A Meta-Analysis

Acta Cardiologica, 2023
The resting full-cycle ratio (RFR), a new non-congestive resting index, is commonly used for physiological evaluations of coronary arteries. This study aims to evaluate the accuracy of RFR in detecting coronary artery stenosis with hemodynamic ...

The Influence of Microcirculatory Dysfunction on the Resting Full Cycle Ratio Compared to Fractional Flow Reserve [PDF]

Cardiovascular Revascularization Medicine, 2023
BACKGROUND: The relation between the resting full cycle ratio (RFR) and fractional flow reserve (FFR) is not fully understood. This study aims to investigate the influence of coronary microvascular dysfunction, assessed by the index of microvascular ...

Comparison of quantitative flow ratio (QFR) and instantaneous wave-free ratio (iFR) or resting full-cycle ratio (RFR) during daily routine in the catheterization laboratory

European Heart Journal, 2022
Abstract Background The prognosis of patients with coronary artery disease (CAD) depends strongly on the hemodynamic relevance of the stenosis. The gold standard is the invasive evaluation of the stenosis using Fractional Flow Reserve (FFR), instantaneous wave-free ratio (iFR) or Resting Full-Cycle ...

Comparison of vessel-Fractional Flow Reserve (vFFR) and Quantitative Flow Ratio (QFR) using instantaneous wave-Free Ratio (iFR) or Resting Full-cycle Ratio (RFR) as reference

European Heart Journal
Abstract Background Angiography-based functional assessment remains the state of the art to assess the hemodynamic relevance of intermediate coronary stenoses. In addition to fractional flow reserve (FFR), adenosin free indices like instantaneous wave-free ratio (iFR) or resting full-cycle ratio (RFR)
