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 !
