A 72-year-old man, with a history of use of the SKS technique using two sirolimus-eluting stents (SES) measuring 3.0/28-mm for the proximal segment of the left circumflex artery (LCx) and obtuse marginal branch 12 years prior, presented with unstable angina. A coronary angiography demonstrated restenosis at the distal edge of the implanted stent (Fig. 1a). The OFDI revealed several patterns of neointimal coverage over the neo-metal carina and some uncovered struts by neointima; fully covered by the neointima, end-to-end coverage pattern, bridge-like membrane formation, and a single-strut coverage pattern (Fig. 1b–g). The anti-platelet regimens were indefinite low-dose aspirin and a 75 mg of clopidogrel daily for 6 years after the index PCI.
