AB  - In-stent restenosis (ISR) remains a tough problem after percutaneous coronary 
      intervention (PCI) despite advances in technology of drug-eluting stents (DES). A 
      63-year-old man undergoing hemodialysis was diagnosed with non-ST elevation acute 
      coronary syndrome (NSTE-ACS). An emergency coronary angiography (CAG) revealed 
      severe stenosis in the middle left circumflex artery (LCx). After pre-dilatation 
      with non-compliant balloon, primary PCI was successfully performed with DES 
      implantation. Four months after, CAG was performed again and verified ISR of LCx 
      under diagnosis of recurrent NSTE-ACS. Subsequently multimodality intravascular 
      imaging assessment was performed for the ISR lesion. Optical frequency domain 
      imaging showed the eccentric protruding mass with irregular surface with 
      high-backscatter, whereas angioscopy revealed the in-stent bump with yellow 
      color. The ISR lesion was successfully treated by drug-coated balloon 
      angioplasty. However, he suffered recurrent NSTE-ACS five months later. CAG 
      revealed de novo stenotic lesions not only in re-restenosis of LCx but also in 
      proximal left anterior descending artery and ostium of right coronary artery. He 
      was scheduled to undergo coronary artery bypass grafting for three-vessel 
      disease. Multimodality assessment is useful to diagnose the recurrent restenosis 
      lesion with calcified nodule. <Learning objective: In-stent restenosis (ISR) is 
      rarely recurrent even after drug-eluting stent (DES) implantation. In-stent 
      protruding bump is observed in types of ISR morphology by intravascular imaging, 
      and the finding suggests the possibility of recurrent ISR. Diagnosis of the 
      morphology is sometimes difficult, but multimodality imaging assessment is useful 
      to distinguish the ISR tissue.>.
