OCT derived endpoints
thrombi, stenosis, culprit lesion, hyperplasia
THROMBI, PLAQUE, STENOSIS, HYPERPLASIA
The following endpoints were analyzed: percentage of strut coverage > 40 µm, stent strut significant malapposition (distance between the luminal part of the strut to intimal border > 300 µm), malapposition volume, mean neo-intimal area, neo-intimal hyperplasia area at maximal obstruction, percentage of stenosis by neo-intimal hyperplasia, neo-intimal hyperplasia volume at maximal obstruction and maximal neo-intimal thickness at maximal obstruction. Luminal and stent areas and volumes as well as stent expansion were measured at baseline and follow-up. Definitions for some selected OCT derived endpoints are given in Fig. At baseline, visual assessment of plaque composition, calcium characterization and the presence of thrombi and tissue protrusion was performed for the site of maximal obstruction (culprit lesion) as well as proximal and distal vessel references (within 5 mm to stent edges). The total number of struts analyzed per lesion and the mean number of struts per cross-section were also reported.
