Noninvasive FFR Derived From Coronary CT Angiography
Fro Un an Ca pa R0 Fe su an Ca Sa He oth OBJECTIVES The purpose of this study was to determine whether noninvasive fractional flow reserve derived from computed tomography (FFRCT) predicts coronary revascularization and outcomes and whether its addition improves efficiency of referral to invasive coronary angiography (ICA) after coronary computed tomography

RATIONALE AND OBJECTIVES To compare computer-generated interpretation of coronary computed tomography angiography (cCTA) by commercially available COR Analyzer software with expert human interpretation. MATERIALS AND METHODS This retrospective Health Insurance Portability and Accountability Act‑compliant study was approved by the institutional review board. Among 225 consecutive cCTA examinat...
متن کاملInstantaneous 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 کاملPredictors of inaccurate coronary arterial stenosis assessment by CT angiography.
OBJECTIVES This study sought to investigate the clinical and imaging characteristics associated with diagnostic inaccuracy of computed tomography angiography (CTA) for detecting obstructive coronary artery disease (CAD) defined by quantitative coronary angiography (QCA). BACKGROUND Although diagnostic performance metrics of CTA have been reported, there are sparse data on predictors of diagno...
