Sex Differences in Fractional Flow Reserve Utilization. [PDF]

J Clin Med
Background: The literature review shows that female patients are more frequently underdiagnosed or suffer from delayed diagnosis. Recognition of sex-related differences is crucial for implementing strategies to improve cardiovascular outcomes. We aimed to assess sex-related disparities in the frequency of fractional flow reserve (FFR)-guided procedures

Fractional flow reserve [PDF]

Indian Journal of Thoracic and Cardiovascular Surgery, 2018
Physiologically driven coronary revascularization has been shown to be superior in terms of better outcomes and optimum resource utilization for percutaneous interventions. However, its applicability to surgical myocardial revascularization lacks evidence base. GRAFITTI Trial aims at bridging this gap and Dr.

Artificial intelligence approaches to predict coronary stenosis severity using non-invasive fractional flow reserve [PDF]

, 2020
Fractional flow reserve is the current reference standard in the assessment of the functional impact of a stenosis in coronary heart disease. In this study, three models of artificial intelligence of varying degrees of complexity were compared to ...

Standardization of Fractional Flow Reserve Measurements [PDF]

Journal of the American College of Cardiology, 2016
Pressure wire-based fractional flow reserve is considered the standard of reference for evaluation of the ischemic potential of coronary stenoses and the expected benefit from revascularization. Accordingly, its application in daily practice or for research purposes has to be as standardized as possible to avoid technical or operator-related artifacts ...

Use of the instantaneous wave-free ratio or fractional flow reserve in PCI [PDF]

, 2017
BACKGROUND: Coronary revascularization guided by fractional flow reserve (FFR) is associated with better patient outcomes after the procedure than revascularization guided by angiography alone.

Real-Life Fractional Flow Reserve [PDF]

Circulation, 2017
Article, see p 2241 Rare are the approaches that have changed our understanding of coronary artery disease as has fractional flow reserve (FFR). After extensive animal and human validation work and hypothesis-generating observational studies,1 larger randomized trials with a superiority design have reshaped our therapeutic strategies in stable ...
