Orsiro has also shown superior strut 
coverage compared to Resolute Integrity 
• Orsiro v.s. Resolute Integrity (n=44, 1:1 randomization) 
• To access “early healing pattern of 2nd and 3rd 
generation DES” 
• Primary endpoint: Stent strut coverage at 3 months 
• Presented at EuroPCR 2013 by T. Kiviniemi, PI: P 
Karjalainen 
• No significant baseline differences between study arms 
• Most interesting result – Uncovered struts at 3 months 
Orsiro 3.9% vs. Resolute Integrity 8.9%, p<0.001 
• Conclusion 
“Sirolimus-eluting stents with bioabsorbable polymer 
were more completely covered compared to 
zotarolimus-eluting stents with durable polymer at 3 
months after PCI for ACS”

Shear stress and healing 
CONCLUSIONS 
The ultrathin-strut biodegradable polymer sirolimus-eluting stent: 
– comparable long-term clinical performance to the current state-of-the-
art newer- generation thin-strut durable polymer Xience everolimus-
eluting stent in broadly inclusive patient populations. 
– despite the lack of randomized data, low rates of TLF and ST in high-risk 
subgroups of patients with increased risk of cardiovascular events (diabetes 
mellitus, small vessels, long lesions, complex coronary lesions, multivessel 
disease, chronic total occlusion, or STEMI) similar to rates in lower-risk 
patients. 
– potential clinical superiority of the Orsiro SES over the best-in-class newer-
generation durable polymer Xience everolimus-eluting stent in the subgroup of 
patients with STEMI warrants confirmation in the ongoing BIOSTEMI 
randomized controlled trial. 
 Thank You for your attention!
