Incomplete arterial healing 8 years after the implantation of sirolimus-eluting stent. In vivo visualization by optical coherence tomography.

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.
