      A case of severely calcified neoatherosclerosis-embedded stent struts clearly documented with optical coherence tomography imaging

      A 65-year-old Japanese man using peritoneal hemodialysis due to diabetic nephropathy underwent a planned coronary angiography as a preoperative examination. Fourteen years earlier, he had undergone a percutaneous coronary intervention due to acute myocardial infarction and had been implanted with a bare-metal stent in the left anterior descending coronary artery. Although his condition had run a benign course without any recurrence of cardiovascular events, coronary angiography was performed 14 years later in preparation for a living-donor kidney transplantation. Coronary angiography revealed less than 50% restenosis (Figure A). Although Figure B indicates circumferentially covered stent struts, the homogeneous neointima pattern observed ...
