    In-stent neoatherosclerosis: are first generation drug eluting stents different than bare metal stents? an optical coherence tomography study

    Purpose: In-stent neoatherosclerosis has been recognised in pathologic specimens of bare metal stents (BMS), and recently in first generation drug eluting stents (1st-DES), as well. However, in vivo data are scarce. By optical coherence tomography, we investigated the incidence and morphological characteristics of neoatherosclerosis (NA) very late after BMS or 1st-DES implantation. Methods: From 1/1/2007 to 31/1/2012, 52 patients from two institutions underwent >24 months follow-up OCT assessment of a BMS or a 1st-DES (13 BMS – 39 1st-DES). NA was characterized using criteria for native atherosclerosis. Results: BMS had longer follow-up interval but no differences in ...
