Figure legends
Figure 1 – Angiography A, B - PCI and DES to the proximal right coronary artery (RCA) for an AMI five years earlier. C - Pre-dilatation and thrombectomy not able to completely restore flow (TIMI 1). D - Implantation of a DES at nominal pressure immediately restored TIMI 3 flow. E, F - Post-dilatation with a NC balloon corrected stent under-expansion and improved stent apposition.
Figure 2 - OCT A - Presence of large amount of white and red thrombus, excessive neointima formation and
a previously implanted and under-expanded stent. B - Five days later, OCT-guided stent optimization showed residual thrombus, under-expansion and malapposition of the newly implanted stent. C – Aggressive post-dilatation with NC balloon corrected stent under-expansion and improved stent apposition.
