Figure 2. The figure outlines the strengths and limitations of angiography-guided, imaging-guided, invasive functionally-guided and non-invasive functionally-guided approaches to investigating NCLs during PCI procedures. NCLs: Non-culprit lesion; PCI: percutaneous coronary intervention; FFR: fractional flow reserve; NHPR: non-hyperemic pressure ratio.
