Fig. 1.
Measurements of strut apposition. The distances between the endo-luminal surface of the strut reflection and the vessel wall were measured. (A and B) shows OCT image of SES and strut measurements and represents malapposition. (C and D) shows OCT image of PES and strut measurement shows normal stent apposition. (E and F) represents OCT image of ZES and its measurement shows normal stent apposition. Definition of malapposition: ≥ 160 µm for SES, ≥ 130 µm for PES, ≥ 110 µm for ZES.7 OCT, optical coherence tomography; SES, sirolimus-eluting stent; PES, paclitaxel-eluting stent; ZES, zotarolimus-eluting stent.
