1.5 and 3 Tesla quantification of myocardial perfusion reserve in comparison to fractional flow reserve [PDF]

Journal of Cardiovascular Magnetic Resonance, 2013
Methods Thirty-four patients referred for coronary x-ray angiography with suspected or known coronary artery disease underwent cardiac magnetic resonance imaging (CMR) at 1.5 and 3 Tesla, and additionally FFR measurement in LAD, CX and RCA. MPR was calculated in 544 myocardial segments at both field strenghts.

Diagnostic efficacy of CCTA and CT-FFR based on risk factors for myocardial ischemia

Journal of Cardiothoracic Surgery, 2022
Background Coronary artery coronary computed tomography angiography (CCTA) can observe the degree of coronary artery stenosis and fractional flow reserve (FFR) can diagnose hemodynamic abnormalities caused by coronary artery stenosis.

Clinical and Vessel Characteristics Associated With Hard Outcomes After PCI and Their Combined Prognostic Implications

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Cardiac death or myocardial infarction still occurs in patients undergoing contemporary percutaneous coronary intervention (PCI). We aimed to identify adverse clinical and vessel characteristics related to hard outcomes after PCI and to ...

Effect of Plaque Burden and Morphology on Myocardial Blood Flow and Fractional Flow Reserve

Journal of the American College of Cardiology, 2018
Atherosclerotic plaque characteristics may affect downstream myocardial perfusion, as well as coronary lesion severity.This study sought to evaluate the association between quantitative plaque burden and plaque morphology obtained using coronary computed tomography angiography (CTA) and quantitative myocardial perfusion obtained using [15O]H2O positron

Fractional flow reserve after previous myocardial infarction [PDF]

European Heart Journal, 2007
Marques and colleagues have conducted an interesting study on microvascular resistance of viable tissue within an infarcted area. 1 This study is important, not only from a conceptual point of view, but also because it has several relevant implications for the applicability of MIBI spect and fractional flow reserve (FFR) measurement in patients with ...

Retracted: Microvascular resistance reserve in the presence of functionally significant epicardial stenosis and changes after revascularization

Physiological Reports, 2023
In the presence of functionally significant epicardial lesions, microvascular resistance reserve (MRR) calculation needs incorporation of collateral flow.

Myocardial perfusion imaging by single-photon emission tomography (MPI SPECT) versus Instantaneous wave-free ratio (IFR) for assessment of functional significance of intermediate coronary artery lesions

The Egyptian Heart Journal, 2019
Background The aim of our work was to compare the myocardial perfusion imaging by single-photon emission tomography (MPI-SPECT) as a non-invasive, relatively non-expensive test versus the instantaneous wave-free ratio (IFR) for the evaluation of ...

Fractional Flow Reserve-Based Patient Risk Classification

Diagnostics, 2023
Cardiovascular diseases (CVDs) are a leading cause of death. If not treated in a timely manner, cardiovascular diseases can cause a plethora of major life complications that can include disability and a loss of the ability to work.
