Study Outline Clinical events were adjudicated by an independent CEC Target vessel revascularizations were analysed by an independent QCA core lab. All patients were monitored for 12 months; only 3 pts (0.16%) were lost for FU.
Study Outline Inclusion criteria • All patients eligible for PCI • Life expectancy of > 5 years Exclusion criteria • No dual antiplatelet therapy for 12 months • Cardiogenic shock at presentation • Expected planned major surgery within 1 month • Participation in another trial • No informed consent
Endpoints • Primary endpoint all death, non fatal MI and Target Vessel Revascularization (TVR) at 12 months follow-up • Secondary endpoints • cardiac death, non fatal MI, ischemic driven TLR rate at 12 months follow-up. • all death, non fatal MI, TVR at 3 and 5 years follow-up • incidence of definite, probable or possible stent thrombosis at 12 months, 3 and 5 years

Conclusions • In an all-comerpopulation, reflecting real world, implantation of the Everolimus eluting Xience V stent significantly reduced major adverse cardiac events compared to the Paclitaxel eluting Taxus Liberté stent • Superiority of the Everolimus eluting Xience V stent was reached mainly due to less early stent thrombosis and less target lesion revascularization
