Fractional flow reserve and beyond

Heart, 2013
In stable coronary artery disease, clinical decision making regarding percutaneous coronary intervention (PCI) of coronary artery stenoses is optimally based upon an evaluation of the functional severity of the coronary lesion.1 ,2 As such, intracoronary (IC) physiology has emerged as a standard diagnostic modality in the contemporary armamentarium of ...

Additional value of deep learning computed tomographic angiography-based fractional flow reserve in detecting coronary stenosis and predicting outcomes

Acta Radiologica, 2021
Background Deep learning (DL) has achieved great success in medical imaging and could be utilized for the non-invasive calculation of fractional flow reserve (FFR) from coronary computed tomographic angiography (CCTA) (CT-FFR).

Fractional Flow Reserve

2015
Fractional flow reserve has been increasingly popular in assessing the severity of coronary stenosis in indeterminate lesions. Moreover, it has had an increasing role as a prognostic indicator and has been incorporated in different angiographic scores to assess the appropriate revascularization strategy.

Fractional Flow Reserve

2020
Since its introduction in 1994 fractional flow reserve (FFR) has revolutionized the way cardiologists and cardiac surgeons view myocardial revascularization. The FFR is currently considered the gold standard for assessment of functional significance of coronary stenosis and the expected benefit from revascularization.

Physiologically personalized coronary blood flow model to improve the estimation of noninvasive fractional flow reserve.

Medical Physics (Lancaster), 2021
PURPOSE Coronary outlet resistance is influenced by the quantification and distribution of resting coronary blood flow. It is crucial for a more physiologically accurate estimation of fractional flow reserve (FFR) derived from computed tomography ...

An introduction to fractional flow reserve

British Journal of Cardiac Nursing, 2012
Fractional flow reserve (FFR) is an index derived from coronary pressure measurements to assess the functional significance of a coronary stenosis. It is performed during coronary angiography for patients with stable angina when a moderate coronary stenosis is found.
