Noninvasive FFR derived from coronary CT angiography in the management of coronary artery disease: technology and clinical update
After a decade of clinical use of coronary computed tomographic angiography (CCTA) to evaluate the anatomic severity of coronary artery disease, new methods of deriving functional information from CCTA have been developed. These methods utilize the anatomic information provided by CCTA in conjunction with computational fluid dynamics to calculate fractional flow reserve (FFR) values from CCTA i...

CONTEXT Coronary computed tomographic (CT) angiography is a noninvasive anatomic test for diagnosis of coronary stenosis that does not determine whether a stenosis causes ischemia. In contrast, fractional flow reserve (FFR) is a physiologic measure of coronary stenosis expressing the amount of coronary flow still attainable despite the presence of a stenosis, but it requires an invasive procedu...

To the Editor: We commend Nakazato et al for their excellent article entitled, “Non-Invasive Fractional Flow Reserve Derived From CT Angiography (FFRCT) for Coronary Lesions of Intermediate Stenosis Severity: Results From the DeFACTO Study.” The wellperformed multicenter study concluded that FFR CT possessed higher diagnostic performance for ischemic for coronary lesions of intermediate stenosi...
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 fractional flow reserve derived from computed tomography angiography for coronary lesions of intermediate stenosis severity: results from the DeFACTO study.
BACKGROUND Fractional flow reserve derived from computed tomography angiography (FFRCT) is a noninvasive method for diagnosis of ischemic coronary lesions. To date, the diagnostic performance of FFRCT for lesions of intermediate stenosis severity remains unexamined. METHODS AND RESULTS Among 407 vessels from 252 patients at 17 centers who underwent CT, FFRCT, invasive coronary angiography, an...
