In-Stent Restenosis due to Stent Recoil After Third-Generation Drug-Eluting Stent Implantation

Abstract

A 72-year-old man with a heavily calcified coronary lesion underwent percutaneous coronary intervention (PCI) using a third-generation drug-eluting stent (DES) with thin stent struts. Two months after the PCI, in-stent restenosis due to stent recoil (SR) occurred. An intravascular ultrasound (IVUS) revealed deformed stent struts and heavily calcified coronary plaque. The SR probably occurred due to persistent vessel compression as a result of heavily calcified coronary plaque. We should consider using a DES with thick stent struts rather than a third-generation DES with thin stent struts in patients with a heavily calcified coronary lesion.
