Assessment and Quantitation of Stent Results by Intracoronary Optical Coherence Tomography

Maehara A, Matsumura M, Mintz GS. Keywords: dissection; malapposition; OCT; stent; minimal stent area

ABSTRACT

Optical coherence tomography evaluation of post stent 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.
