The BVS concept. From the chemical structure to the vascular biology: the bases for a change in interventional cardiology

Bioresorbable vascular scaffolds (BVS), the fourth generation of percutaneous coronary intervention (PCI), aim to improve the long-term outcomes of PCI facilitating the restoration of the physiology of the treated vessels when the scaffold dismantling process is completed. In this paper we will review all the technical aspects as well as the potential clinical indications of this technology.
