CT-FFR sensitivity was 91.5% and specificity 60.3% with strong variation between studies. CCTA correctly ruled out CAD in 52% of all patients, but 42% of positive CCTAs were false positives. CT-FFR correctly ruled out CAD in 47% of all patients included in this meta-analysis, but showed...
This can be achieved by combination of coronary CTA with myocardial CT perfusion (myocardial CTP) (Fig. 6) or with fractional flow reserve-CT (FFR-CT). Download: Download full-size image Fig. 6. Decreased attenuation in the subendocardial layer of the inferior wall corresponding to prior ...
Coronary CTA provides abundant information on coronary atherosclerosis beyond the assessment of coronary stenosis. With advanced processing technology, coronary CTA enables characterization of plaque subtypes and assessment of the hemodynamic significance of stenoses using CT-FFR, which further guides management...
“The critical role of CTA in the diagnosis and management of coronary artery disease continues to drive every decision we make, ensuring the right patients are getting the right care at the right time,” said Campbell Roger...
Reply: Plaque Characterization by Coronary Computed Tomography Angiography and Association With Acute Coronary Syndrome Detection of coronary ischemic lesions by fractional flow reserve (FFR) has been established as the gold standard. In recent years, novel computer based methods have emerged and they can...
I think Coronary CTA with Heartflow One is the future of cardiology. It helps us understand the disease from whether you have non-obstructive or a low, mild disease to a severe disease that actually needs intervention. ” –Dr. Milind Parikh,Director of Preventive ...
Only 50% of obstructed vessels with ≥ 50% luminal narrowing by CTA show abnormal MPI[48]. We previously indicated that 64-slice CTA alone was not always sufficient to assess the functional significance of anatomic stenoses, especially stenoses of intermediate grade (Figure 4). When stenosis ...

FFR values <= 0.80 will be considered to be ischemia causing. All subjects (N = 270; 10 investigative sites) will undergo coronary CTA (single- or dual-source CT scanners with a minimum of 64 slices) and invasive coronary angiography with FFR. Patients with insufficient quality of coronary ...
