Post-stenting fractional flow reserve vs coronary angiography for optimization of percutaneous coronary intervention (TARGET-FFR)

European Heart Journal, 2021
Aims  A fractional flow reserve (FFR) value ≥0.90 after percutaneous coronary intervention (PCI) is associated with a reduced risk of adverse cardiovascular events.

Fractional flow reserve derived from computed tomography coronary angiography in the assessment and management of stable chest pain: the FORECAST randomized trial

European Heart Journal, 2021
Aims  Fractional flow reserve (FFRCT) using computed tomography coronary angiography (CTCA) determines both the presence of coronary artery disease and vessel-specific ischaemia.

Intravascular Imaging versus Physiological Assessment versus Biomechanics—Which Is a Better Guide for Coronary Revascularization

Diagnostics, 2023
Today, coronary artery disease (CAD) continues to be a prominent cause of death worldwide. A reliable assessment of coronary stenosis represents a prerequisite for the appropriate management of CAD.

Prognostic Implications of Resistive Reserve Ratio in Patients With Coronary Artery Disease

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Resistive reserve ratio is a thermodilution‐based index which integrates both coronary flow and pressure. Resistive reserve ratio represents the vasodilatory capacity of interrogated vessels including both epicardial coronary artery and ...

Coronary flow reserve and microcirculatory resistance in patients with coronary tortuosity and without atherosclerosis

Journal of International Medical Research, 2020
Objective Coronary tortuosity may affect epicardial coronary arterial blood flow. This study aimed to investigate the effect of coronary tortuosity on coronary flow reserve and the coronary microcirculation in patients without apparent coronary ...

Fractional flow reserve versus angiography for guiding percutaneous coronary intervention.

New England Journal of Medicine, 2009
BACKGROUND In patients with multivessel coronary artery disease who are undergoing percutaneous coronary intervention (PCI), coronary angiography is the standard method for guiding the placement of the stent.

Impact of physiologically diffuse versus focal pattern of coronary disease on quantitative flow reserve diagnostic accuracy

Catheterization and cardiovascular interventions, 2021
Fractional flow reserve (FFR) and instantaneous wave‐free ratio (iFR) disagree in about 20% of intermediate coronary lesions. As the physiological pattern of coronary artery disease has a significant influence on FFR‐iFR discordance, we sought to assess ...
