ESC Forum on Drug Eluting Stents European Heart House, Nice, 27-28 September 2007.

Drug-eluting stents (DES) were introduced into clinical practice in 2002 in order to reduce restenosis that occurred in 15–25% of patients receiving bare-metal stents (BMS).1–3 Subsequent trials with different types of DES confirmed their efficacy in this regard.4 However, late stent thrombosis was reported as early as 2004, typically in patients discontinuing dual anti-platelet therapy.5 At the European and World Congress of Cardiology in Barcelona 2006, alarming data were presented on a worse long-term prognosis following DES implantation compared with BMS.6,7 As a result both randomized controlled trials and registry data were scrutinized to validate these concerns, bearing in mind the differential values of both types of studies.8,9 Furthermore, the worldwide discussion on the long-term safety and efficacy of DES triggered the European Society of Cardiology together with the European Association for Percutaneous Cardiovascular Interventions to organize a forum on DES. On 27 and 28 September 2007, key opinion leaders in (interventional) cardiology and representatives from industry and regulatory bodies gathered in the European Heart House with the intention to review: (i) the most recent data on the long-term efficacy (reduction of restenosis, re-intervention) and safety (late stent thrombosis, myocardial infarction, mortality) of DES and its effects on outcome (survival, event-free survival), (ii) specific indications for DES; (iii) health economical analyses currently performed with DES; (iv) the DES registration process in Europe; (v) current and possible future trial designs. The overall goal was to provide general recommendations to the medical community for the use, clinical development, and future assessment of DES. In several randomized controlled trials comparing sirolimus-eluting stents (SES) or paclitaxel-eluting stents (PES) and BMS, increased rates of death or myocardial infarction were observed at follow-up, beyond the first year,6–8,10 while no excess …
