e-Ultimaster Bifurcation sub-analysis
Overview
・4,395 patients with Bifurcation lesions treated with Ultimaster™ DES showed acceptable clinical outcomes with TLF 5.1%.
・Ultimaster™ with POT technique improve clinical outcomes.
Study Design
Primary Endpoint
Target lesion failure at 1 year
・Cardiac death, target vessel MI or clinically driven target lesion revascularization

Result
1 year outcomes in all bifurcation patients
1 year clinical outcomes
Procedural differences based on big data by propensity matched analysis
One vs Two stent
Both Ultimaster implantation with one-stent technique and that with two-stent technique showed excellent results. These results indicate Ultimaser can shift treatment strategy from one-stent strategy to two-stent strategy without increasing TLF.
1 year clinical outcomes
POT vs no POT
UltimasterTM implantation with POT technique improved clinical outcomes in treatment of bifurcation lesions. UltimasterTM is the one and only stent that proved the effectiveness of POT technique in bifurcation lesions.
1 year clinical outcomes
Final kissing balloon vs No final kissing balloon
Both UltimasterTM implantation with FKB technique and that with No FKB technique showed excellent results. These results indicate that in cases requiring FKB technique not so much, UltimaserTM may be able to skip FKB technique while maintaining low event rate.
1 year clinical outcomes
True bifurcation vs other bifurcation
Good performance of UltimasterTM for both true and other bifurcation lesions.
