CORONARY BIFURCATION IMAGING
Impact of Bifurcation Angle on Incomplete Stent Apposition
Author: Masahiro Yamawaki, MD, Saiseikai Yokohama City Eastern Hospital, Japan
PURPOSE
To investigate the impact of the “Link free and distal re-wiring(LFD)” condition and bifurcation angle on 9-month OCT findings after 1-stenting with final kissing inflation(FKI).
CONCLUSION
- High bifurcation (>55°) angle should be care in case of link-free on carina and distal wiring , due to uncorrected stent distortion on the opposite of side branch (SB) and distal main vessel (MV) by final kissing balloon inflation (FKI), but incomplete stent apposition (ISA) in MV decreased after 9 months
- Impact of bifurcation angle on 9-month OCT data was minor than those of “link and re-wire position” before FKI in this registry.
- FKI with optimal condition under 3D-OCT guidance reduced uneven neointima proliferation, ISA and uncovered strut after 9 months.
- Further study is required to demonstrate clinical impact of OCT guided bifurcation treatment.
