Use and Value of Fractional Flow Reserve in Coronary Arteriography.

An editorial is presented which argues against the optimal revascularization threshold of fractional flow reserve (FFR) and outcomes from high-volume center in China. Topics include percutaneous coronary intervention (PCI) has achieving complete revascularization, in patients with multivessel disease; and less invasive techniques have developed to determine FFR from computed tomography angiography without a pressure wire.
