OCT aspect of metallic platform stent (A), Absorb BVS (B) and Magmaris (C), after implantation. The PLLA/PDLLA struts of Absorb BVS device do not determine a shadow behind in the OCT image (B), as the light can cross them. On the contrary, Magmaris scaffold (C), as well as metallic platform stent (A), creates a shadow behind the metallic struts. OCT, optical coherence tomography.
