Figure 1. The distinct resorption pattern of bioabsorbable magnesium scaffolds. A) - C) Optical coherence tomography (OCT) images after bioabsorbable magnesium scaffold (MgS) implantation. The bright metallic MgS struts are clearly depicted. The previous metallic stent is also partially visualised as a double metal layer. D) - F) OCT findings at one-year follow-up. The inner metallic layer is no longer visible. Instead, multiple intimal “humps” (yellow asterisks) are recognised (these characteristic images were identified in 92% of the frames within the MgS). Very rarely (6% of frames), images consistent with small protruding thrombus casting dorsal shadow (D: +) were noticed. ...
