  15. Conclusions  In this all-comers setting a low TLF rate of 5.1% was observed within the first 12 months, which implies safety and effectiveness of the Orsiro Hybrid Stent  The results observed in this “real world” population demonstrate a low TLF rate comparable to other state of the art DES at 12 months.  The low TLF rate is not only observed in the overall cohort, but also in patients with STEMI and multi-vessel disease as seen in this post-hoc analysis  In comparison with other published trials in patients with STEMI, the Orsiro Hybrid Stent shows a low TLF rate.
