Evaluation of asymptomatic persons at an intermediate pre-test probability of coronary heart disease or atherosclerotic cardiovascular disease by Framingham risk scoring or Pooled Cohort Equations (see Appendix) who have an equivocal or uninterpretable exercise or pharmacological stress test or have resting...
DEEPVESSEL FFR is a AI-enabled, non-invasive CT fractional flow reserve (FFRCT) analysis. It is an augmentative physiological functional assessment of the coronary arteries using coronary computer tomography angiograms. The software can reduce unnecessary invasive testing, improve patient safety, and lo...
Figure 2. Fewer cardiac downstream tests were performed post CT-FFR (n=6356 (17.8%) vs 8073 (14.7%), p<0.001) including fewer invasive coronary angiograms (ICA) (n=4128 (11.6%) vs 5437 (9.9%); OR 0.84 (0.81, 0.88), p<0.001). CONCLUSION. The introduction of CT FFR as a new ...

Computational simulations of coronary artery blood flow, using anatomical models based on clinical imaging, are an emerging non-invasive tool for personalized treatment planning. However, current simulations contend with two related challenges – incompl
结论基于冠状动脉CTA影像计算的AccuFFR ®ct系统可以作为评估冠状动脉狭窄引起功能性缺血的一种快速、准确的计算工具。 关键词: FFR;FFR-CT;计算流体力学;冠状动脉CTA;狭窄。 ABSTRACT ObjectiveTo compare non-invasive coronary blood fractional flow reserve based on coronary CTA (FFR-CT) imaging with invasive...
A HeartFlowFFR-CT example showingcomparison with a CT scan of heavily calcified coronary arteries. The lesion looks severe anatomically on CT, but it not significant enough to qualify for stenting according to the FFR-CT. The CT imaging is sent to an outside vendor so it can be run through...
Both found CTA can help determine if if a patient should be sent for a diagnostic angiogram, or if a non-invasive exam is good enough to determine if revascularization is needed.[13,14] "This is very relevant as we try to reduce the number of invasive coronary angiograms in a COVID-...
B, CT angiogram demonstrating obstructive stenosis of the mid portion of the right coronary artery (RCA) and an FFRCT value of 0.87, indicating no vessel ischemia. Invasive coronary angiogram demonstrates obstructive stenosis of the mid portion of the RCA and a measured FFR value of 0.88, ...
[25]. Furthermore, in our center, patients with very high coronary artery calcium scores (as assessed by the clinical team on the day of the scan) were referred directly for an invasive X-ray coronary angiogram, without performing a contrast enhanced coronary CTA, in order to avoid ...
