Deploying bioresorbable vascular scaffolds—tardus, altius, amplius!!

Abstract

Current generation bioresorbable vascular scaffolds (BVS) have thick struts and relatively low radial strength; meticulous deployment is required to prevent underexpansion while avoiding stent fracture. The current study suggests safety of very high-pressure (mean 28 atm) post-dilation of BVS with a noncompliant balloon. Duration of inflation and inflation pressure stabilization are important factors that influence the extent of optimal stent expansion and should be studied in future attempts to optimize BVS deployment.
