Previous midterm follow-up reports after implantation of the Absorb™ everolimus-eluting bioresorbable scaffold (BRS; Abbott Vascular, Santa Clara, CA, USA) in stable coronary artery disease and acute coronary syndrome have shown an increase of scaffold thrombosis leading to an excess of the device-oriented composite endpoint (DOCE: a composite of cardiac death, target vessel myocardial infarction [TVMI], and clinically driven target lesion revascularisation [CD-TLR])1. In contrast, in the six-month primary report of ABSORB STEMI: the TROFI II Study (NCT01986803)2, which randomised patients with ST-elevation myocardial infarction (STEMI) to receive either the Absorb BRS or the XIENCE metallic everolimus-eluting stent (EES; Abbott Vascular), optical frequency domain imaging (OFDI)-derived healing score was comparable between the BRS arm and the EES arm. The aim of this report was to present the three-year clinical outcome results of the BRS and the metallic EES at the time when full resorption of the scaffold device can be expected.
