TCT-355 Serial (Baseline and Follow-Up) Optical Coherence Tomography Analysis of the Causes of Stent Failure

In-stent restenosis (ISR) can be caused by neointimal hyperplasia, chronic stent underexpansion, or mechanical problems that develop during follow-up. A total of 45 patients had optical coherence tomography (OCT) at the time of second-generation drug-eluting stent implantation and for treatment of
