ABSTRACT
Optical coherence tomography evaluation of poststent results includes stent expansion as the absolute minimum stent area ratio by comparing the minimum stent area with the proximal and distal reference lumen areas or mean stent area
defined as the total stent volume divided by the analyzed stent length;
stent strut malapposition defined when the distance from the center of
the blooming artifact and the surface of plaque is greater than the sum
of stent thickness and polymer thickness; tissue protrusion through the
stent struts; semiquantitative residual thrombus evaluation; and stent
edge dissection.
