Projected Costs and Consequences of Computed Tomography‐Determined Fractional Flow Reserve

摘要

BackgroundRandomized trials have shown that fractional flow reserve (FFR) guided percutaneous coronary intervention (PCI) improves clinical outcome and reduces costs compared with visually guided PCI. FFR has been measured during invasive coronary angiography (ICA), but can now be derived noninvasively from coronary computed tomography (CT) angiography (cCTA) images (FFRCT). The potential value of FFRCT in clinical decision making is unknown.
