TCT-389 Pre-Clinical Evaluation of a Novel Thin Strut (85 μm) Ultra-High Molecular Weight PLLA Sirolimus-Eluting Bioresorbable Scaffold: A Comparative Multi-Modality Imaging-Based Study

First generation Bioresorbable Scaffolds (BRS) are more prone to mechanical failure and vascular recoil despite their redundant surface area and wall thickness (∼157-microns). The development of DES-like BRS is key for the future of this field. In this study, we tested the biological performance
