Optical coherence tomography in in-stent restenosis: A challenge made easier

Abstract

In-stent restenosis (ISR) has been an area of concern for the interventional cardiologists since the era of bare-metal stents (BMS). Although the incidence of ISR is more with BMS as compared to drug-eluting stents, due to the underlying pathophysiological differences, between the two; the latter has a more accelerated course and is difficult to treat. In this case report, we try to address this issue of difficult treatment of ISR and the benefit of using optical coherence tomography in these situations.
