e-Ultimaster Bifurcation | Terumo Interventional Systems

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

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.

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.

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.
