Diagnostic Accuracy and Feasibility of Quantitative Flow Ratio at Low Frame Rate Angiography: The Prospective Multicentre Australian AVALON Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

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 ...

Algorithmic versus expert human interpretation of instantaneous wave-Free Ratio (iFR) coronary pressure-wire pullback data [PDF]

, 2019
Background Interpretation of instantaneous wave-Free Ratio (iFR) pressure-wire pullback data can be complex and is subjective. Objectives To investigate if algorithmic interpretation (AI) of iFR pressure-wire pullback data would be non-inferior to ...

Coronary Stenosis Physiology and Novel Technologies

Rambam Maimonides Medical Journal, 2020
An accurate functional assessment of coronary artery stenosis is pivotal in the management and clinical outcomes of patients. The hemodynamic relevance of coronary artery stenoses can be assessed using coronary flow surrogates, namely fractional flow ...

Instantaneous wave-free ratio guided multivessel revascularisation during percutaneous coronary intervention for acute myocardial infarction: study protocol of the randomised controlled iMODERN trial

BMJ Open, 2021
Introduction Recent randomised clinical trials showed benefit of non-culprit lesion revascularisation in ST-elevation myocardial infarction (STEMI) patients. However, it remains unclear whether revascularisation should be performed at the index procedure

L'envolée épistémique de la recherche comptable en économie financière : une étude historique sur la conception de l'utilité de la comptabilité* The Epistemic Rise of Accounting Research in Financial Economics: A Historical Study on the Conception of the Usefulness of Accounting

Contemporary Accounting Research, EarlyView.
RÉSUMÉ L'étude publiée par Ball et Brown en 1968 (ci‐après « BB68 ») est principalement reconnue pour son affirmation selon laquelle la comptabilité de l'époque était utile pour les investisseurs, s'inscrivant alors en contradiction avec la littérature comptable normative faisant office d'autorité. Or, une telle affirmation n'allait pas de soi.

TCTAP A-003 Sex Differences in Instantaneous Wave-free Ratio (iFR) or Fractional Flow Reserve (FFR) Guided Strategy

Journal of the American College of Cardiology, 2019
Instantaneous wave-free ratio (iFR)- and fractional flow reserve (FFR)-guided strategy showed comparable clinical outcomes in patients with coronary artery disease. This study sought to evaluate impact of sex on iFR- and FFR-guided treatment.

Impact of Preoperative Cardiac Screening Modality on Cardiovascular Outcomes After Liver Transplantation

Clinical Transplantation, Volume 40, Issue 9, September 2026.
ABSTRACT Introduction Cardiovascular (CV) disease is a leading cause of morbidity and mortality after liver transplantation (LT). Coronary computed tomography angiography (CCTA) has increasingly replaced stress testing (ST) for CV risk assessment in LT candidates with intermediate‐to‐high CV risk, although comparative evidence remains limited.
