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.

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.

Influence of contrast media dose and osmolality on the diagnostic performance of contrast fractional flow reserve [PDF]

, 2017
Background—Contrast fractional flow reserve (cFFR) is a method for assessing functional significance of coronary stenoses, which is more accurate than resting indices and does not require adenosine.

Prognostic value of global longitudinal strain in hypertrophic cardiomyopathy: A systematic review and meta‐analysis

Clinical Cardiology, Volume 45, Issue 12, Page 1184-1191, December 2022., 2022
Abstract Background As previously reported, impairment of left ventricular global longitudinal strain (LVGLS) is associated with myocardial fibrosis, arrhythmias, and heart failure in hypertrophic cardiomyopathy (HCM) patients. Hypothesis This study aimed to estimate the association between LVGLS measured by echocardiography and major adverse ...

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-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.

Non-Invasive Flow Ratio (NiFR) Measurement based on Angiography Images [PDF]

Journal of Biomedical Physics and Engineering, 2021
Background: Fractional flow reserve (FFR) is a gold standard to assess the impact of stenosis on the blood flow. The FFR method enhances diagnostic accuracy, lessens the need for stenting, and reduces costs.
