"Interpretation

Biodegradable polymer biolimus-eluting stents are as safe and efficacious as the current standard of a thin-strut everolimus-eluting stent with a durable biocompatible polymer. We need to follow-up patients for longer to show whether the biolimus-eluting stent reduces the risk of stent thrombosis after 1 year when compared with the everolimus-eluting stent."
