Evaluation of FFR, WSS, and TPF Using CCTA

Noninvasive Evaluation of Ischemia Causing Coronary Stenosis, Wall Shear Stress, and Total Plaque Force Using Coronary CT Angiography (CCTA) and Physics-based Analytic Model Derived From Conservation of Energy

To assess the feasibility of CT-derived computed fractional flow reserve (FFRCT), wall shear stress and total plaque force on coronary atherosclerotic plaque and to collect the preliminary data to apply those parameters for the prediction of clinical outcomes in patients with coronary artery stenosis.

Inclusion Criteria:

• Consecutive patients with available CCTA within 3 months of invasive angiography and invasive imaging methods (IVUS or OCT)

Exclusion Criteria:

• Poor CT images (unable to reconstruct 3 dimensional coronary artery model)
