The haemodynamic effects of collateral donation to a chronic total occlusion : implications for patient management [PDF]

, 2015
Physiological lesion assessment in the form of Fractional Flow Reserve (FFR) is now well established for the purpose of guiding multi-vessel revascularization.

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.

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.

On the Instability of Fractional Reserve Banking [PDF]

arXiv, 2023
This paper develops a dynamic monetary model to study the (in)stability of the fractional reserve banking system. The model shows that the fractional reserve banking system can endanger stability in that equilibrium is more prone to exhibit endogenous cyclic, chaotic, and stochastic dynamics under lower reserve requirements, although it can increase ...

Functional SYNTAX Score for Risk Assessment in Multivessel Coronary Artery Disease [PDF]

, 2011
ObjectivesThis study was aimed at investigating whether a fractional flow reserve (FFR)-guided SYNTAX score (SS), termed “functional SYNTAX score” (FSS), would predict clinical outcome better than the classic SS in patients with multivessel coronary ...

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

Instantaneous Wave‐free Ratio versus Fractional Flow Reserve to Guide PCI

New England Journal of Medicine, 2017
Background The instantaneous wave‐free ratio (iFR) is an index used to assess the severity of coronary‐artery stenosis. The index has been tested against fractional flow reserve (FFR) in small trials, and the two measures have been found to have similar ...

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.

Fractional flow reserve versus angiography in guiding management to optimize outcomes in non–ST-elevation myocardial infarction (FAMOUS-NSTEMI): rationale and design of a randomized controlled clinical trial [PDF]

, 2013
<p>Background: In patients with acute non–ST-elevation myocardial infarction (NSTEMI), coronary arteriography is usually recommended; but visual interpretation of the angiogram is subjective.
