Physiology guided coronary revascularization using a hybrid RFR-FFR strategy for Non ST elevation acute coronary syndrome [PDF]

Scientific Reports
To develop a hybrid resting full-cycle ratio (RFR)- fractional flow reserve (FFR) decision-making approach for physiology-guided coronary revascularization in patients with non-ST elevation acute coronary syndrome (NSTE-ACS).

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 significance using fractional flow reserve (FFR) as the reference standard.

Use of physioLogy to evaluaTe procedural Result After percutaneous coronary intervention of Chronic Total Occlusion (ULTRA-CTO): protocol for a prospective, single-arm, multicentre, exploratory study [PDF]

BMJ Open
Introduction Post-percutaneous coronary intervention (PCI) fractional flow reserve (FFR) is associated with future major adverse cardiac events and may reflect residual ischaemia and suboptimal stent result (SSR).

Clinical Outcome of Lesions With Discordant Results Among Different Invasive Physiologic Indices　― Resting Distal Coronary to Aortic Pressure Ratio, Resting Full-Cycle Ratio, Diastolic Pressure Ratio, Instantaneous Wave-Free Ratio, and Fractional Flow Reserve ―

Circulation Journal, 2019
We evaluated the 2-year clinical outcomes of deferred lesions with discordant results between resting and hyperemic pressure-derived physiologic indices, including resting distal to aortic coronary pressure (resting Pd/Pa), instantaneous wave-free ratio (iFR), resting full-cycle ratio (RFR), diastolic pressure ratio (dPR), and fractional flow reserve ...

Interpretation of Discordance Between Non-Hyperemic Pressure Ratios and Fractional Flow Reserve: Potential Mechanisms and Clinical Implications [PDF]

Reviews in Cardiovascular Medicine
Invasive coronary angiography remains the gold standard for assessing and treating coronary artery disease (CAD). While the decision to intervene on a severely stenotic lesion in acute coronary syndrome (ACS) can be straightforward, assessing the ...

"Trust the eye, but verify". Case report

Кардиоваскулярная терапия и профилактика, 2023
Coronary angiography is today a routine method for assessing the coronary arteries. However, in practice, invasive cardiologists daily face difficulties in assessing the coronary system. The publication considers the management of an elderly patient with

Coronary Flow Variations Following Percutaneous Coronary Intervention Affect Diastolic Nonhyperemic Pressure Ratios More Than the Whole Cycle Ratios

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Post–percutaneous coronary intervention (PCI) fractional flow reserve ≥0.90 is an accepted marker of procedural success, and a cutoff of ≥0.95 has recently been proposed for post‐PCI instantaneous wave‐free ratio.

The Impact of Age on the Physiological Assessment of Borderline Coronary Stenoses

Medicina, 2023
Background and Objectives: Coronary angiography is the gold standard for diagnosing coronary artery disease (CAD). In the case of borderline changes, patients require further diagnosis through ischemia assessment via one of the recommended methods of ...

Comparison of Fractional Flow Reserve with Resting Non-Hyperemic Indices in Patients with Coronary Artery Disease

Journal of Cardiovascular Development and Disease, 2023
Guidelines recommend using hyperemic (FFR) and non-hyperemic (iFR/RFR) methods of evaluating coronary artery stenoses in patients with coronary artery disease.
