JACC. Cardiovascular interventions, 2016 This study sought to assess the impact of a wide range of mean right atrial pressure (Pra) on fractional flow reserve (FFR) measurements.FFR invasively assesses the ischemic potential of coronary stenoses. FFR is calculated as the ratio of mean distal coronary pressure (Pd) to mean aortic pressure (Pa) during maximal hyperemia. The Pra is considered to

Cost-Effectiveness of Percutaneous Coronary Intervention in Patients With Stable Coronary Artery Disease and Abnormal Fractional Flow Reserve [PDF]
Circulation, 2013 BACKGROUND The Fractional Flow Reserve Versus Angiography for Multivessel Evaluation (FAME) 2 trial demonstrated a significant reduction in subsequent coronary revascularization among patients with stable angina and at least 1 coronary lesion with a ...

Coronary Fractional Flow Reserve
American Journal of Roentgenology, 2015OBJECTIVE. This article presents the basic definitions and concepts of fractional flow reserve (FFR), a focused understanding of the need for hyperemia during assessment, key clinical studies supporting its use, and an introduction to newer noninvasive methods using FFR CT. CONCLUSION.

Fractional flow reserve and beyond
Heart, 2013In 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 ...

Fractional flow reserve is an index of the physiological significance of a coronary stenosis, defined as the ratio of maximal myocardial blood flow in the presence of the stenosis to the theoretically normal maximal myocardial blood flow (i.e. in the absence of the stenosis).

Landmark Fractional Flow Reserve Trials
Interventional Cardiology Clinics, 2015Fractional flow reserve (FFR) has become widely used for physiologic assessment of intermediate coronary lesions. The Fractional Flow Reserve to Determine Appropriateness of Angioplasty in Moderate Coronary Stenoses (DEFER) trial established the safety of deferring angioplasty for moderate lesions that are not functionally significant.

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.

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.
