Diagnostic performance of noninvasive fractional flow reserve derived from coronary computed tomography angiography in ischemia-causing coronary stenosis: a meta-analysis



Diagnostic performance of noninvasive fractional flow reserve derived from coronary computed tomography angiography in ischemia-causing coronary stenosis: a meta-analysis



Japanese Journal of Radiology 34(12): 795-808



Fractional flow reserve based on coronary computed tomographic angiography (CCTA; FFRCT) can evaluate functional severity in coronary artery disease (CAD). This study investigated the diagnostic value of FFRCT for determining CAD severity. Medline, Cochrane, EMBASE, and Google Scholar databases were searched until June 16, 2016 using the following search terms: fractional flow reserve, coronary computed tomography angiography, myocardial ischemia. Randomized controlled trials, two-arm prospective studies, and retrospective studies were included in the analysis. Twenty-one studies were included with a total of 2216 subjects and 2798 vessels. FFRCT, sensitivity per-vessel and per-patient were ≥82% and specificity was ≥73% for diagnosis of ischemia. FFRCT had better diagnostic accuracy and discrimination than CCTA. This study indicates that FFRCT may be a good tool for screening and diagnosing of myocardial ischemia in patients with CAD.
