RESUMEN
The time course of complete arterial healing after drug eluting stent implantation is unknown. We present a case of incomplete endothelialization and late stent malapposition identified by optical coherence tomography 8 years after a sirolimus-eluting stent implantation, which was not related with any adverse clinical event.

Optical coherence tomography (OCT) is an optical analogue of intravascular ultrasound that has recently been proposed as a high-resolution imaging method for plaque characterization. Histology-controlled studies have shown that OCT can evaluate the characteristics of culprit lesions, such as fibrous cap thickness, fibrous cap macrophage density, lipid core and intracoronary thrombus. We describe a case where OCT was used to evaluate the culprit lesion morphology in a patient with acute myocardial infarction. The patient was treated with stent implantation. OCT was also used to confirm good stent apposition.
