A 72-year-old woman was referred to our center with recurrent chest tightness over the previous year which had exacerbated 1 week prior. The patient had a history of self-made pol-yurethane-covered stent (PU-CS) implantation 6 months prior because of a proximal left anterior descending (LAD) perforation after high-pressure post-dilatation. Diagnostic angiography revealed in-stent restenosis (ISR) at the PU-CS site, stent under-expansion at the middle LAD (undilatable with a 2.75 mm noncompliant balloon inflated at 24 atmospheres for 60 s), and tight stenosis with a heavily calcified lesion at the middle circumflex (uncrossable with a 1.25 mm compliance balloon). Optical coherence tomography (OCT) revealed excessive neointimal proliferation at the ISR site and under-expanded stent struts with
