Impact of Bifurcation Angle on Incomplete Stent Apposition

European Bifurcation Club 2019, EBC 2019 - Barcelona, Spain 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.

Why I prefer IVUS in bifurcation guidance

European Bifurcation Club 2014, EBC 2014 - Bordeaux, France LIVE BIFURCATION STENTING GUIDANCE: OCT, IVUS, FFR & ANGIO Why I prefer IVUS in bifurca3on guidance Author: Masahiro Yamawaki, MD, PhD, Saiseikai Yokohama City Eastern Hospital, Japan SUMMARY The mechanism of luminal widening by FKI was stretching vessel wall. FKI corrected carina/plaque-shift in about 30%. Plaque shift dominantly occurred(50%) The vessel anatomy assessed by IVUS before intervention /FKI was predictable for plaque/ carina shift, and associated with residual SB ostium stenosis despite FKI. CONCLUSION Why I prefer IVUS in bifurcation guidance” Because we can check optimal result after stenting by IVUS. In addition, IVUS before- and during PCI helps us to .... know precise anatomy, and predict SB compromise as well as luminal widening after FKI. make decision of final strategy of bifurcation-PCI make our procedure logical and predictable !
