Background: Differences in early arterial healing patterns after stent implantation between biodegradable and
durable polymer based new generation drug-eluting stents are not well understood. The aim of this study was
to compare the healing patterns of a novel rapid breakdown (≤8 weeks) biodegradable polymer sirolimuseluting
stent (BP-SES) with a durable polymer everolimus-eluting stent (EES) using intravascular optical
coherence tomography (OCT) at 4 months
