Percutaneous Coronary Intervention with Everolimus-Eluting Bioresorbable Vascular Scaffolds in Diffuse Coronary Artery Disease: Current Knowledge and Future Perspectives

Abstract

The optimal percutaneous treatment of diffuse coronary artery disease (CAD) remains an unsolved issue. Bioresorbable scaffold (BRS) technology has been developed to overcome the disadvantages of metallic drug-eluting stents (DES) due to their permanent struts. Through the resorption process, BRS may provide complete vascular restoration, which appears very attractive in the treatment of diffuse CAD. However, robust evidence on the use of BRS in this setting is lacking and recent data have raised concerns about the safety of this novel technology, especially when BRS are used in complex CAD or without adequate protocol implantation. This review aims at summarizing current evidence and future perspectives on Absorb BRS implantation in complex CAD, such as in distal coronary segments involvement and diffused disease.
