Fractional flow reserve as a surrogate for inducible myocardial ischaemia

Nature Reviews Cardiology, 2013
Documentation of inducible myocardial ischaemia, related to the coronary stenosis of interest, is of increasing importance in lesion selection for percutaneous coronary intervention (PCI). Fractional flow reserve (FFR) is an easily understood, routine diagnostic modality that has become part of daily clinical practice, and is used as a surrogate ...

CT Assessment of Myocardial Perfusion and Fractional Flow Reserve

Progress in Cardiovascular Diseases, 2015
Coronary computed tomography angiography (CTA) offers a non-invasive method to detect coronary plaque and stenosis. However, to date, CTA has been most useful as a method of ruling out coronary artery disease (CAD) among patients with low to intermediate pretest probability of significant CAD.

The myocardial flow reserve in patients with heart failure with preserved ejection fraction

Heart and Vessels, 2022
To evaluate the myocardial flow reserve (MFR) and myocardial blood flow (MBF) parameters in patients with heart failure with preserved ejection fraction (HFpEF) and to assess their relationship with the severity of HF and the levels of soluble ST2 (sST2).

Fractional Flow Reserve-Guided Multivessel Angioplasty in Myocardial Infarction: 3-year follow-up with cost benefit analysis of the Compare-Acute trial.

EuroIntervention, 2020
AIMS The Compare-Acute trial showed superiority of fractional flow reserve (FFR)-guided acute complete revascularization compared to culprit-only treatment in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD ...

Myocardial Perfusion and Fractional Flow Reserve

2013
Myocardial CT perfusion imaging is a rapidly evolving technology that allows assessment of the functional significance of potentially obstructive coronary stenosis. The opportunity for quantification of myocardial perfusion is the greatest potential advantage of CT compared with other perfusion techniques.

Instantaneous Wave-Free Ratio (iFR) Correlates With Fractional Flow Reserve (FFR) Assessment of Coronary Artery Stenoses and Myocardial Bridges in Children.

The Journal of invasive cardiology, 2020
OBJECTIVES Instantaneous wave-free ratio (iFR) has been proven to correlate with coronary flow reserve better than fractional flow reserve (FFR) and is non-inferior to FFR in guiding coronary revascularization in ischemic heart disease. There has been no

Myocardial Fractional Flow Reserve and Clinical Outcome

1997
There is ample inferential evidence that patients with physiologically significant stenoses are at increased risk1. Patients with proven coronary artery disease and in whom signs of myocardial ischemia are observed at low workload have an adverse event rate which is four times higher than in those with similarly severe stenoses but in whom ischemia can

Myocardial fractional flow reserve

Herz, 2011
Revascularization of coronary artery lesions should be based on objective evidence of ischemia, as recommended by the guidelines of the European Society of Cardiology. However, even in the case of stable coronary artery disease and elective percutaneous coronary intervention (PCI), pre-procedural noninvasive stress test results are available in a ...

Comparison of quantitative flow ratio, Pd/Pa and diastolic hyperemia‐free ratio versus fractional flow reserve in non‐culprit lesion of patients with non ST‐segment elevation myocardial infarction

Catheterization and cardiovascular interventions, 2020
To investigate the correlation between quantitative flow ratio (QFR), Pd/Pa, diastolic hyperemia‐free ratio (DFR) and fractional flow reserve (FFR, gold standard) in non‐culprit lesion (NCL) of patients with non ST‐segment elevation myocardial infarction
