In contrast, drug-eluting balloon (DEB) catheters allow short-term passage of the active substance into the vascular Background-The aim of this prospective randomized noninferiority study was to compare the efficacy of paclitaxeleluting balloon (PEB) catheters and everolimus-eluting stents (EES) in the treatment of bare metal stent restenosis. Methods and Results-A total of 136 patients were enrolled in the study. Each treatment group included 68 patients with 74 in-stent restenotic lesions. The primary end point was in-segment late lumen loss (LLL) at 12 months. Secondary end points were the incidence of binary in-stent restenosis and 12-month major adverse cardiac events. The 2-sided 95% confidence interval of LLL difference between treatments (0.149-0.558) was greater than noninferiority margin (0.12), which demonstrates both noninferiority and superiority of PEB treatment. Furthermore, the PEB group had significantly less 12-month LLL than the EES group (0.02 versus 0.19 mm; P=0.0004).
