[Usefulness of intracoronary imaging techniques in the percutaneous treatment of in-stent restenosis].

We report a case of very late bare-metal stent restenosis, in which assessment by two intracoronary imaging techniques (intravascular ultrasound and optical coherence tomography) revealed the underlying mechanism (neoatherosclerosis) and facilitated percutaneous treatment (direct bare-metal stent-in-stent). We also take the opportunity to briefly describe the advantages and limitations of both techniques in this pathology.
