Computed Tomography-Derived Fractional Flow Reserve in the Detection of Lesion-Specific Ischemia
Invasive fractional flow reserve (FFR) is the gold standard for the determination of physiologic stenosis severity and the need for revascularization. FFR computed from standard acquired coronary computed tomographic angiography datasets (FFRCT) is an emerging technology which allows calculation of FFR using resting image data from coronary computed tomographic angiography (CCTA). However, the ...
متن کاملDiastolic fractional flow reserve to assess the functional severity of moderate coronary artery stenoses: comparison with fractional flow reserve and coronary flow velocity reserve.
BACKGROUND Coronary blood flow occurs mainly during the diastolic phase of each cardiac cycle and is mainly dependent on diastolic driving pressure, especially in the left anterior descending coronary artery (LAD). We hypothesized that calculation of the ratio of the diastolic driving pressure of a stenotic LAD to its normal value, namely diastolic FFR (d-FFR), might provide precise insight int...
متن کاملFractional Flow Reserve—Guided Lesion or Patient Management?
Correspondence To the Editor: In one of the latest issues, Hu et al. carried out a national retrospective cohort study and investigated the clinical outcomes and cost of fractional flow reserve (FFR) guided percutaneous coronary intervention (PCI) in daily practice. FFR guided PCI was shown to improve the clinical outcomes with reduced cost, as demonstrated in the literature. We would like to e...
متن کاملIschemia-based Coronary Revascularization: Beyond Anatomy and Fractional Flow Reserve
Treatment strategies for patients with coronary artery disease (CAD) should be based on objective evidence of inducible ischemia in the subtended myocardium to improve clinical outcomes, symptoms, and cost-effectiveness. Fractional flow reserve (FFR) is the most verified index to-date for invasively evaluating lesion-specific myocardial ischemia. Favorable results from large clinical trials tha...
متن کاملFractional Flow Reserve
Traditionally, coronary artery disease was assessed using coronary angiographic guidance. Significant lesions were determined by the coronary angiographer. However, interobserver variability showed a significant limitation of interpretation of coronary angiography. Stent deployment and apposition were also evaluated based on angiographic appearance only. Risk factors for stent thrombosis and in...
