In patients with SES restenosis, PEB provided much better clinical, angiographic outcomes than conventional BA.

Late restenosis occurs after PCB angioplasty for DES-ISR lesions.

Background-We have sometimes noted abnormal angiographic coronary dilatation, <50% of the reference vessel, at the site of sirolimus-eluting stent implantation, suggesting contrast staining outside the stent struts and named this finding peri-stent contrast staining (PSS

EES implantation was more effective for PCB failure in preventing subsequent TLR than repeat PCB angioplasty because of better angiographic results.

Small vessels, diffuse type restenosis and dialysis patients were still the predictors of recurrent restenosis in patients treated with SES for ISR of BMS.
