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. Improved scaffold design and deployment techniques might mitigate early bioresorbable scaffolds risk enhancing the late benefit of complete resorption.
