CENTURY II Bifurcation sub-analysis
Overview
- 5-year clinical outcomes of PCI-treated bifurcation lesions whereby a single stent approach was utilized in 93% of the cases showed similar good safety and efficacy for both Ulimaster™ and Xience stents.
- Favorable TLF trend in true bifurcation subgroup, observed in Ultimaster™-DES-treated patients, warrant further exploration in larger cohorts.
