53  Single center trial – (Università degli Studi di Napoli - Federico II)  PI: F. Piscione  195 consecutive patients underwent PCI with either Genous or DES (SES or PES) implantations in the period May – July 2006.  Dual anti-platelet therapy for 1 month post-Genous implant and 9 months post DES implant.  Clinical follow-up (average FU 10.1 ± 3.2 months).  Follow-up major adverse clinical events (MACE): cardiac death, MI, target vessel re-PTCA, CABG.

57  Coronary stents have always faced a significant risk of early and late stent thrombosis  Whereas second-generation drug-eluting stents have improved early and subsequent outcomes, their biocompatibility is still at stake  Recent studies on EPC stents suggest the promising role of this device  The asymptotic coronary stent will likely be a bioabsorbable device with drug-elution and EPC capabilities
