Hybrid Instantaneous Wave-Free Ratio–Fractional Flow Reserve versus Fractional Flow Reserve in the Real World

Frontiers in Cardiovascular Medicine, 2017
BackgroundThe instantaneous wave-free ratio (iFR) is a novel method to assess the ischemic potential of coronary artery stenoses. Clinical trial data have shown that iFR has acceptable diagnostic agreement with fractional flow reserve (FFR), the ...

Influence of contrast media dose and osmolality on the diagnostic performance of contrast fractional flow reserve [PDF]

, 2017
Background—Contrast fractional flow reserve (cFFR) is a method for assessing functional significance of coronary stenoses, which is more accurate than resting indices and does not require adenosine.

How much flow is enough: the use of fractional flow reserve in chronic limb-threatening ischemia in a series of patients with isolated occlusive tibial disease

Journal of Vascular Surgery Cases and Innovative Techniques, 2023
The role of the fractional flow reserve to guide lower extremity peripheral vascular intervention, specifically in chronic limb-threatening ischemia, has remained unclear.

Three-Dimensional Angiographic Characteristics versus Functional Stenosis Severity in Fractional and Coronary Flow Reserve Discordance: A DEFINE FLOW Sub Study

Diagnostics, 2022
Background: Coronary angiography alone is insufficient to identify lesions associated with myocardial ischemia that may benefit from revascularization.

Coronary Microcirculation Downstream Non‐Infarct‐Related Arteries in the Subacute Phase of Myocardial Infarction: Implications for Physiology‐Guided Revascularization

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Concerns exist about reliability of pressure‐wire‐guided coronary revascularization of non‐infarct‐related arteries (non‐IRA). We investigated whether physiological assessment of non‐IRA during the subacute phase of myocardial infarction might

Deep learning analysis of the myocardium in coronary CT angiography for identification of patients with functionally significant coronary artery stenosis [PDF]

, 2017
In patients with coronary artery stenoses of intermediate severity, the functional significance needs to be determined. Fractional flow reserve (FFR) measurement, performed during invasive coronary angiography (ICA), is most often used in clinical ...

Diabetes does not impact the diagnostic performance of contrast-based fractional flow reserve: insights from the CONTRAST study [PDF]

, 2017
Background: Adenosine-free coronary pressure wire metrics have been proposed to test the functional significance of coronary artery lesions, but it is unexplored whether their diagnostic performance might be altered in patients with diabetes. Methods:

Computed Tomography-Derived Fractional Flow Reserve: Developing A Gold Standard for Coronary Artery Disease Diagnostics. [PDF]

Rev Cardiovasc Med
In recent years, a new technique called computed tomography-derived fractional flow reserve (CT-FFR) has been developed. CT-FFR overcomes many limitations in the current gold-standard fractional flow reserve (FFR) techniques while maintaining a better ...

Fractional Flow Reserve

JACC: Cardiovascular Interventions, 2010
Multivessel coronary artery disease is frequently encountered during cardiac catheterization of patients with acute coronary syndromes ([1,2][1]). Current guidelines from the American College of Cardiology/American Heart Association and European Society of Cardiology discourage treatment of non-
