3. Figure 2
Distribution of post-PCI FFR values. Distribution of post-PCI mean FFR values in chronological order. Red dots represent studies with balloon angioplasty only. The shaded zone delineated by blue and red lines represents FFR between 0.75 and 0.80.

4. Figure 3
Cumulative incidence of post-PCI FFR values. Cumulative post-PCI mean FFR values incidence showed by the blue line and dots. Note that 80% of studies presented post-PCI mean FFR values between 0.85 and 0.95 (shaded zone) and that, in 50% of studies, 0.90 was obtained (red lines).

Correlations between baseline and procedural data and post-PCI FFR. Correlations between prior MI, post-PCI stenosis, post-PCI lumen diameter, pre-PCI FFR, and post-PCI FFR values.

6. Figure 5
A and B, Meta-regression analysis of stent or DES rate and post-PCI FFR values. A, Data show a significant relationship between % of stent implantation (vs balloon angioplasty alone) and post-PCI FFR values. B, No significant difference was observed in post-PCI FFR values with DES compared with BMS.

7. Figure 6
A and B, Meta-regression analysis of post-PCI FFR values and repeat PCI (A) or MACE (B). A, Data show that the higher the post-PCI FFR value, the lower the risk of repeat PCI. Post-PCI FFR ≥0.90 is associated with <10% risk of repeat PCI. B, Data show that the higher the post-PCI FFR value, the lower the risk of MACE.

Difference in post-PCI FFR values if focal or diffuse disease. Illustration of the effect of stent deployment in focal lesion (A) and diffuse (B) disease and the immediate post-PCI FFR values.
