Bioresorbable Coronary Scaffold Technologies: What's New?

To overcome the not negligible metallic drug-eluting stents adverse events rate, the polymeric or metallic bioresorbable scaffolds were designed to provide early drug delivery and mechanical support followed by complete resorption. However, the long-term evidence, focusing on the leading Absorb BVS technology, showed higher events compared with drug-eluting stents. This review discusses the lights and shadows of the current bioresorbable scaffolds according to their mechanical properties and biodegradation profile and suggests possible perspective on these technologies.
