Noninvasive Diagnosis of Ischemia Causing Coronary Stenosis Using Coronary CT Angiograms (CCTA) : Comparison of Transluminal Attenuation Gradient (TAG) and Fractional Flow Reserve Computed From CCTA (FFR CT)
In Brief
An observational study for Coronary Artery Disease. Targeting 80 participants across 1 site.
Detailed Summary
Coronary computed tomographic angiography (CCTA) has emerged as a non-invasive test, accurately evaluate anatomic coronary artery stenosis. However, anatomically-obstructive coronary stenosis by CCTA demonstrates an unreliable relationship to lesion-specific ischemia. Recently, with the advance of imaging reconstruction and analysis technique, several novel parameters computed from CCTA were suggested to have added value in determining the ischemia-causing coronary stenosis. In this study, diagnostic performance of transluminal attenuation gradient (TAG) and fractional flow reserve computed form CCTA (FFR-CCTA) for the presence of hemodynamically-significant coronary stenosis, as determined by fractional flow reserve (FFR).
