New generation bioresorbable scaffold technologies: An update on novel devices and clinical results

Bioresorbable scaffolds (BRS) represent a novel horizon in interventional cardiology and may lead to some potential long-term advantages including the restoration of vasomotion, positive remodeling and a reduced incidence of late and very-late scaffold thrombosis (ScT). This technology, introduced to overcome limitations of current metallic drug-eluting stents (DES), is constantly and rapidly evolving with many companies working on bioresorbable devices. The aim of this review is to present an update on the most promising scaffolds that are under development.
