Coronary flow reserve calculated from pressure measurements in humans : Validation with positron emission tomography

, 1994
Background Experimental studies have shown that fractional flow reserve (defined as the ratio of maximal achievable flow in a stenotic area to normal maximal achievable flow) can be calculated from coronary pressure measurements only.

Use of Intracoronary Pressure Wire Assessment and Association With Outcomes: Insights From the British Cardiovascular Intervention Society National Database

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Despite recommendations in international guidelines, Intracoronary pressure wire assessment (PWA) utilization remains limited in clinical practice. This study aims to describe (i) trends of PWA during Percutaneous coronary interventional (PCI), (ii) factors that predict its application, and (iii) association with in‐hospital ...

Clinical Impact of Adherence to Fractional Flow Reserve Guidance in Acute Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Fractional flow reserve (FFR) is established to guide revascularization in stable coronary disease and non‐culprit lesions in acute coronary syndromes (ACS). However, real‐world adherence to FFR guidance across the spectrum of ACS presentations, including ambiguous culprit scenarios, remains incompletely characterized.

Comparative Analysis of the Feasibility of Myocardial Blood Flow Index Versus CT-FFR in the Diagnosis of Suspected Coronary Artery Disease

Reviews in Cardiovascular Medicine
Background: Using fluid dynamic modeling, noninvasive fractional flow reserve (FFR) derived from coronary computed tomography angiography (CCTA) data provides better anatomic and functional information than CCTA, with a high diagnostic and discriminatory

Comparison of Fractional Flow Reserve and Myocardial Perfusion Imaging in Saphenous Vein Grafts

Catheterization and Cardiovascular Interventions
ABSTRACTBackgroundRevascularization decision‐making for saphenous vein grafts (SVGs) relies on angiographic lesion severity estimation, as studies on fractional flow reserve (FFR) for detecting ischemia in SVGs are scarce.AimsTo compare FFR and quantitative coronary angiography (QCA) of SVGs against myocardial perfusion imaging (MPI) and to establish ...

Prediction of fractional flow reserve with angiographic DILEMMA score

, 2017
Objective: Angiographic assessment of stenosis has limited predictive value for functionally significant lesions compared with fractional flow reserve (FFR). The recently developed angiographic DILEMMA score, which consists of minimal lumen diameter (MLD)

Maximum Allowable Contrast Dose and Risk of Acute Kidney Injury After Coronary Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Recent studies have questioned whether iodinated contrast is causally related to acute kidney injury (AKI). AIM We pursed a contemporary analysis to determine the impact of contrast dose on AKI following coronary procedures in an era of lower contrast doses and less nephrotoxic agents.

Incidence of Periprocedural Myocardial Injury and Infarction After Intravascular Lithotripsy for Calcified Coronary Artery Stenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular lithotripsy (IVL) has emerged as an effective technique for modifying heavily calcified coronary plaques, facilitating optimal stent expansion while minimizing procedural complications. However, data on periprocedural myocardial injury (PMI) and infarction (PPMI) following IVL remain scarce.
