Accuracy of Intravascular Ultrasound-Based Fractional Flow Reserve in Identifying Hemodynamic Significance of Coronary Stenosis.

Circulation. Cardiovascular Interventions, 2021
BACKGROUND Ultrasonic flow ratio (UFR) is a novel method for fast computation of fractional flow reserve (FFR) from intravascular ultrasound images. The objective of this study is to evaluate the diagnostic performance of UFR using wire-based FFR as the ...

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

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.

Five‐Year Outcomes with PCI Guided by Fractional Flow Reserve

New England Journal of Medicine, 2018
BACKGROUND We hypothesized that fractional flow reserve (FFR)–guided percutaneous coronary intervention (PCI) would be superior to medical therapy as initial treatment in patients with stable coronary artery disease.

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 ...

Fractional Flow Reserve-Based Patient Risk Classification

Diagnostics, 2023
Cardiovascular diseases (CVDs) are a leading cause of death. If not treated in a timely manner, cardiovascular diseases can cause a plethora of major life complications that can include disability and a loss of the ability to work.

Fractional Flow Reserve: An Updated Review [PDF]

Clinical Cardiology, 2014
ABSTRACTRevascularization of ischemia‐producing coronary lesions is widely used in the management of coronary artery disease. However, some coronary lesions appear significant on the conventional angiogram when they are truly non–flow limiting. For this reason, it is becoming increasingly important to determine the coronary physiology.
