Longitudinal Elongation, Axial Compression, and Effects on Strut Geometry of Bioresorbable Vascular Scaffolds : Insights From 2- and 3-Dimensional Optical Coherence Tomography Imaging

Recently described, metallic drug-eluting stent longitudinal distortion is a mechanical phenomenon that leads to stent compression and strut separation (“pseudofracture”) during percutaneous coronary intervention [(1)][1]. Conversely, bioresorbable vascular scaffolds (BVS; Absorb, Abbott
