    Early restenosis of resorbable magnesium scaffolds: Optical coherence tomography findings

    Resorbable Magnesium Scaffolds (RMS) represent an interesting alternative to current drug‐eluting stents. Current data from clinical trials seems to confirm good performance of these new devices with low rates of late device failure. Little is known about mechanisms leading to RMS failure. Herein, we present the first description of an early RMS in‐scaffold restenosis. Optical coherence tomography (OCT) analysis at implantation detected acute non‐severe malapposition and underexpansion as main promoters of RMS failure. OCT during in‐scaffold restenosis intervention confirmed early severe neointimal proliferation and RMS late recoil and dismantling as the main mechanisms of device failure ...
