Diagnosis of Ischemia-Causing Coronary Stenoses by Noninvasive Fractional Flow Reserve Computed From Coronary Computed Tomographic Angiograms
نویسنده
چکیده
Methods Computation of FFR from CCTA data was performed on 159 vessels in 103 patients undergoing CCTA, invasive coronary angiography, and FFR. Independent core laboratories determined FFRCT and CAD stenosis severity by CCTA. Ischemia was defined by an FFRCT and FFR 0.80, and anatomically obstructive CAD was defined as a CCTA with stenosis 50%. Diagnostic performance of FFRCT and CCTA stenosis was assessed with invasive FFR as the reference standard.

Instantaneous wave-free ratio derived from coronary computed tomography angiography in evaluation of ischemia-causing coronary stenosis
The instantaneous wave-free ratio (iFR) closely related to fractional flow reserve (FFR) is a adenosine-independent physiologic index of coronary stenosis severity. We sought to evaluate whether iFR derived from coronary computed tomographic angiography (iFRCT) can be used as a novel noninvasive method for diagnosis of ischemia-causing coronary stenosis.We retrospectively enrolled 33 patients (...
متن کاملFractional Flow Reserve and Coronary Computed Tomographic Angiography
Background: Invasive Fractional Flow Reserve Obstructive coronary artery disease (CAD) produces symptoms and increases the risk of adverse cardiac outcomes. However, determining whether a particular coronary stenosis is responsible for causing myocardial ischemia can be challenging, even with invasive coronary angiography (ICA). To help guide decisions in the cardiac catheterization laboratory,...
متن کاملComputed 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 کاملNoninvasive assessment of cerebral artery stenoses from anatomic computed tomography angiography
Trans-stenotic pressure gradient (TSPG) and fractional flow reserve (FFR) are well-validated hemodynamic indices to assess the ischemic severity of arterial stenoses. However, they have significant restrictions in practice due to invasiveness and high cost. Recently, a noninvasive assessment of FFR from computed tomography (CT) angiography has been well validated in evaluating functional corona...
متن کاملNoninvasive hemodynamic assessment using coronary computed tomography angiography: the present and future
2015 The paradigm has been shifted from anatomy-guided to physiology-guided management of coronary artery disease. Hence, intense attention has been focused on whether hemodynamic assessment can be achieved by noninvasive imaging modalities. Among them, coronary computed tomography (CT) has potentials to allow the assessment of ischemia-causing coronary stenosis due to its excellent spatial res...
