Neointimal regression-induced incomplete coverage of a bare-metal stent in the left main trunk: serial angiographic and angioscopic evidence obtained by 5-year follow-up.
Very late stent thrombosis (VLST), a rare complication of stenting, has been reported to develop more frequently at later than 1 year after the deployment of the drug-eluting stent (DES) compared with the bare-metal stent (BMS). However, the causes for the difference in the incidence remain unknown. Serial angioscopy on 1,591 and 1,952 days after BMS deployment in a Japanese male patient with acute myocardial infarction revealed incomplete neointimal coverage (INC) without the development of cardiovascular event. Therefore, the potential development of VLST remains undeniable in BMS-deployed patients who had INC.
