Abstract
A 72-year-old male was treated. First percutaneous coronary intervention (PCI) for chronic total occlusion of proximal left anterior descending artery was performed after rotational atherectomy with 1.5-mm burr. Focal underexpansion of Promus stent occurred due to the heavily calcified plaque. After first restenosis, OCT-guided PCI was performed with 26 atm balloon dilatation. After second restenosis, Resolute Integrity was implanted. After third restenosis, rotational atherectomy with 1.5-, 1.75- and 2.15-mm burrs was performed. All stent struts disappeared at the lesion and Promus Element was implanted. No restenosis occurred after 6 months. Cautious rotational atherectomy could ablate double layer drug-eluting stents effectively.Keywords
