HeartFlow FFRCT for estimating fractional flow reserve from coronary CT angiography

Non-invasive Fractional Flow Reserve Derived from CT Angiography (FFRCT) for Coronary Lesions of Intermediate Stenosis Severity: Results from the DeFACTO Study Nakazato et al: FFRCT for Intermediate Stenosis

Fractional Flow Reserve

Traditionally, coronary artery disease was assessed using coronary angiographic guidance. Significant lesions were determined by the coronary angiographer. However, interobserver variability showed a significant limitation of interpretation of coronary angiography. Stent deployment and apposition were also evaluated based on angiographic appearance only. Risk factors for stent thrombosis and in...

tled, “Non-Invasive Fractional Flow Reserve Derived From CT Angiography (FFRCT) for Coronary Lesions of Intermediate Stenosis Severity: Results From the DeFACTO

To the Editor: We commend Nakazato et al for their excellent article entitled, “Non-Invasive Fractional Flow Reserve Derived From CT Angiography (FFRCT) for Coronary Lesions of Intermediate Stenosis Severity: Results From the DeFACTO Study.” The wellperformed multicenter study concluded that FFR CT possessed higher diagnostic performance for ischemic for coronary lesions of intermediate stenosi...

Invasive and non-invasive fractional flow reserve index in validation of hemodynamic severity of intracoronary lesions

This review discusses visual and functional evaluation of the hemodynamic significance of the degree of stenosis in coronary angiography, with respect to the indications for revascularization. The concept of the coronary flow reserve is defined, and the theoretical assumptions of the invasive measurement of the fractional flow reserve (FFR) are presented. In the following part, the publication ...
