Evaluation of Accuracy of CFD-based RuiXin-FFR by Comparing With Pressure-wire-based FFR

Accuracy of RuiXin-FFR by Comparing With Pressure-wire-based FFR in Detecting Hemodynamically Significant Stenosis: A Prospective Multicenter Study
Coronary Artery Disease (CAD) is the top killer nowadays.
Pressure-wire-based Fractional Flow Reserve (FFR) is the gold standard for measuring ischemia in coronary arteries.
CFD-based RuiXin-FFR, which is noninvasive, is developed recently.
But its accuracy is not verified.
This is a multi-center and prospective study to evaluate the sensitivity, specificity, and accuracy of CFD-based RuiXin-FFR compared with wire-based FFR.

Intervention / Treatment
Detailed Description
The participants are entered with suspended CAD and angiography ischemia between 30%-90% from 6 hospitals in China.
Pressure-wire-based FFR is conducted in the standard protocol by each hospital.
FFR>0.8 is chosen as the threshold to indicate non-ischemia.
CFD-based RuiXin-FFR is performed by Raysight Medical (Shenzhen, China).
CT images are acquired in a standard protocol by each hospital.
Images with poor quality are excluded in this trial.
Based on these images, RuiXin-FFR reconstructs the 3D model of coronary trees and obtains RuiXin-FFR values by conducting CFD simulations in a blinded fashion.
RuiXin-FFR>0.8 is chosen as the threshold to indicate non-ischemia as well.
By comparing the clinical diagnosis outcome of pressure-wire-based FFR and CFD-based RuiXin-FFR, the sensitivity and specificity of the RuiXin-FFR are obtained, which is the primary end point of this trial.
The secondary end point includes the measurement of accuracy, NPV, PPV and ROC of the RuiXin-FFR.

Pressure wire based FFR
Pressure wire based FFR was reference group
|
Pressure wire is inserted into coronary arteries.
The ratio of the average distal pressure and average aorta pressure is FFR.

CT-FFR
CFD-based RuiXin-FFR was test group
|
CT-FFR was evaluated in a blinded fashion with a "Coarse-to-Fine Subpixel" algorithm for lumen contour
