Impact of strut thickness on acute mechanical performance: A comparison study using optical coherence tomography between DESolve 150 and DESolve 100

Rates of scaffold thrombosis after bioresorbable scaffold (BRS) implantation are reported to be higher than after metallic stent (DES) implantation. Thus, second scaffold generations with lower strut thickness might have potential advantages in terms of flow disturbance. We aimed to evaluate the acute performance of a novolimus-eluting BRS with different strut thickness (DESolve system 150 and 100) using optical coherence tomography (OCT) in terms of appropriate scaffold deployment. OCT showed similar post-procedural scaffold geometry and outcome indicating that both BRS may be implanted with good acute performance. However, the data suggest a decreased radial strength for the 100 μm BRS.
