CT-FFR: Clinical Application

Majalah Kardiologi Indonesia, 2018
Invasive fractional flow reserve (FFR) is the gold standard for guiding decision making to identify patients who would benefit from revascularization. Now, computed tomography can also do that by using computational fluid dynamics to calculate fractional

Predictors of postprocedural fractional flow reserve: insights from the FFR-SEARCH study

REC: interventional cardiology (English Edition), 2021
Abstract Introduction and objectives: Patients with a low post-percutaneous coronary intervention (PCI) fractional flow reserve (FFR) are at a higher risk for future adverse cardiac events. The objective of the current study was to assess specific patient and procedural predictors of post-PCI FFR.

Diagnostic Accuracy and Feasibility of Quantitative Flow Ratio at Low Frame Rate Angiography: The Prospective Multicentre Australian AVALON Study. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

Comparative cost-effectiveness analyses of cardiovascular magnetic resonance and coronary angiography combined with fractional flow reserve for the diagnosis of coronary artery disease. [PDF]

, 2014
According to recent guidelines, patients with coronary artery disease (CAD) should undergo revascularization if significant myocardial ischemia is present.

Comparison of FFR and corrected FFR values.

, 2023
Overall, FFR values in the anterior coronary vessels tended to increase, whereas those in the posterior coronary vessels tended to decrease after FFR correction by height difference.

Prognostic Value of Fractional Flow Reserve Measured Immediately After Drug-Eluting Stent Implantation [PDF]

, 2017
The predictive value of fractional flow reserve (FFR) measured immediately after percutaneous coronary intervention (PCI) with drug-eluting stent placement has not been prospectively investigated.

The role of coronary flow reserve (CFR) and fractional flow reserve (FFR) in acute coronary syndrome - systematic review

Bulletin of the Academy of Sciences of Moldova. Medical Sciences, 2022
The methods used to appreciate the degree of coronary stenosis such as CFR and FFR, come to complement the coronary angiography and help the interventional physician during PCI. Furthermore, CFR and FFR measured immediately after reperfusion, in patients with ACS, may act as a prognosis factor for myocardial infarction.Changes in coronary ...
