Various optical coherence tomographic findings in restenotic lesions after sirolimus-eluting stent implantation.
In-stent restenosis (ISR) after sirolimus-eluting stent (SES) implantation rarely occurs, and these lesions are commonly recognized as focal restenosis on angiograms. Optical coherence tomography (OCT) is able to distinguish from several components of intracoronary structures by different signal patterns. We herein report three cases of various OCT images from ISR lesions in spite of similar angiographic findings. Our OCT findings suggested that ISR lesions that develop after SES implantation might be composed of not uniform but various tissues.
