Stent recoil in overlapping stent 18 years after wiktor stent implantation

Abstract

In this paper, we look at the case of a 79 years old male who received a Wiktor stent (WS) implantation for myocardial infarction in proximal left anterior descending artery 18 years ago. Eleven years later, an Everolimus eluting stent (EES; Xience V™) was implanted for the proximal edge restenosis of WS from mid left main trunk to the middle part of WS. Seven years after EES implantation, the angiography and optical coherence tomography revealed in-stent restenosis with severe stent recoil just distal to the overlapping zone of WS. In the present case, stent recoil seems to have occurred due to different radial stiffness and flexibility between the two stents.
