Introduction

The Absorb™ bioresorbable everolimus-eluting scaffold (Abbott Vascular, Santa Clara, CA, USA) was designed to provide a transient vessel scaffold and everolimus elution followed by bioresorption of the polymer, aiming to restore coronary structure and functionality. Although randomised controlled trials comparing the bioresorbable scaffold with the XIENCE everolimus-eluting stent (Abbott Vascular) demonstrated non-inferiority of Absorb compared with XIENCE in target lesion failure (TLF) at one year, the excess of early, late, and very late scaffold thromboses raised safety concerns about the bioresorbable scaffold, leading to a halt of commercialisation of the product. Theoretically, device-related events should diminish ...
