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.
