The impact of residual vessel fractional flow reserve on clinical outcomes: The FAST residual study
Backgrounds Vessel fractional flow reserve (vFFR) allows angiography-based physiological lesion evaluation and virtual percutaneous coronary intervention (PCI) simulation, estimating post-PCI vFFR (residual vFFR). While residual vFFR has been validated against invasive post-PCI fractional flow reserve (FFR), its clinic...
