A 70-year-old man on hemodialysis (HD) presented with stable angina pectoris and coronary angiography revealed intraluminal filling detects in the proximal right coronary artery (RCA) (Fig. 1A, Suppl Video 1). He underwent percutaneous coronary intervention (PCI) in the middle RCA 15 years earlier. Thereafter, PCI was performed for the in-stent restenosis 6 months earlier, and intraluminal filling detects were not observed [Fig. 1B (pre-PCI), Fig. 1C (post-PCI)] and he had continued dual antiplatelet therapy. Optical coherence tomography (OCT) demonstrated the lesion with thrombus protruding into the lumen which was similar to the findings of calcified nodule (CN) (mimic CN) (Fig. 1D, Suppl Video 2). After pre-dilatation with a non-compliant balloon, the lesion was treated with a drug-eluting stent.
