Late endothelialization of first generation pharmacological stents may predispose thrombosis. Both the drug and the polymer of the platform may affect the rate at which this occurs. This is a prospective, multicenter study which randomized 44 patients with acute coronary syndrome to receive sirolimus-eluting stent with bio-absorbable polymer versus zotarolimus-eluting stent with permanent polymer. The…
DEMONSTR8: better endothelial coverage by OCT for the new DES
There is still concern about the safety of drug-eluting stents (DES) due to the possibility of late and very late thrombosis. Dual antiplatelet aggregation for a year is recommended for patients receiving DES. The objective of this study was to test the non-inferiority of a new drug-eluting stent in terms of endothelial coverage after 3…
CENTURY: new clinical results of sirolimus-eluting degradable polymer stent
This new stent is a sirolimus-eluting low-profile cobalt chrome platform (80 µm) with a rapid resorption polymer (3 months). Theoretically, it presents less risk of inflammation of the vessel due to the kinetics of drug elution and polymer degradation. The objective of this study was to test the safety and efficacy of the new device.…
BIOSS: results of the new drug-eluting stent for bifurcations
This new device is a stainless steel platform of 120 µm thick with a sirolimus-eluting bio-absorbable polymer. It has two separate parts: a larger diameter proximal part and a smaller diameter distal part connected by two 1.2 mm structures. The objective of this study was to test (first in man) the device in bifurcations. We…
