Study of the Orsiro Drug Eluting Stent System


  • Target Lesion Failure (TLF) comparable to Xience Prime* although separating over time in favor of Orsiro out to 48 months
  • Absence of definite or probable stent thrombosis also in high risk populations such as diabetic and small vessel subgroup out to 48 months
  • The results of this prospective, randomized study confirms the safety and efficacy of Orsiro

Study Design

A prospective, multi-center, randomized, controlled trial comparing the Orsiro DES to Xience Prime

Coordinating clinical investigators:
Prof. Stephan Windecker, Bern, Switzerland and Dr. Thierry Lefèvre, Massy, France

Primary endpoint:
In-Stent Late Lumen Loss (LLL) at 9 months

Results at 48 months

TLF rate – All subjects

TLF rate – Small vessel population

TLF defined as composite of cardiac death, target vessel Q-wave or non Q-wave Myocardial Infarction (MI), Coronary Artery Bypass Grafting (CABG) and clinically-driven TLR.

All subject stent thrombosis results at 48 months

No definite and no probable stent thrombosis occurred in either arm through 48 months
