Feasibility and results of novel side branch evaluation by customizable measurement planes in OCT – A SORT-OUT V substudy
Author: Niels R. Holm, MD, Aarhus University Hospital, Denmark
BACKGROUND
- SB intervention after jailing is guided by
- TIMI flow
- Ostial DS% (eyeball) – FFR
- Some jailed SBs gain ostial diameter at 8m FU
- SB FFR gain also detected
AIM
- Verify if jailed SBs increases in ostial area
- Assess feasibility of OCT and the Cut Plane technology (QAngioOCT Research Edition 1.0, Medis Specials bv, Leiden, Netherlands) for larger scale SB assessment by main vessel OCT acquisitions
CONCLUSION – SB OSTIA
- Ostial SB MLA was insignificantly increased at 12m FU after jailing by DES
- Cypher tended to have a larger increase in ostial SB MLA compared to Nobori DES
- Neointimal bridging was a common. Clinical implication unsettled
CONCLUSION – FEASIBILITY
- SB ostial assessment from MV OCT was feasible
- Feasibility was limited by:
- Wirer shadows
- Tissue shadowing properties
- Insufficiently cleared blood in lumen
