Immediate post-CTO PCI FFR may underestimate final physiology; leaves open whether delayed reassessment should guide management.
Does fractional flow reserve (FFR) improve at short-term follow-up compared to immediately after successful percutaneous coronary intervention (PCI) for right coronary artery chronic total occlusion?
Fractional flow reserve significantly improves 4 months after successful CTO PCI compared to immediately post-procedure, though many patients still exhibit suboptimal physiological results (FFR <0.90).
