ObjectivesThis study sought to investigate the long-term comparative efficacy and safety of paclitaxel-eluting balloon (PEB), paclitaxel-eluting stent (PES), or balloon angioplasty (BA) for the treatment of drug-eluting stent restenosis.BackgroundThe optimal treatment of drug-eluting stent restenosis remains unknown. Although PEB has shown encouraging results, the long-term clinical efficacy and safety of PEB remains poorly defined.MethodsA total of 402 patients with clinically significant restenosis in limus-eluting stents were randomly assigned to receive PEB (n = 137), PES (n = 131), or BA (n = 134). For this analysis, PEB versus PES and PEB versus BA were compared. The primary efficacy and safety endpoints were target lesion revascularization and the composite of death or myocardial infarction.ResultsAt a median follow-up of 3 years, the risk of target lesion revascularization was comparable with PEB versus PES (hazard ratio [HR]: 1.46, 95% confidence interval [CI]: 0.91 to 2.33; p = 0.11) and lower with PEB versus BA (HR: 0.51, 95% CI: 0.34 to 0.74; p < 0.001). The risk of death/myocardial infarction tended to be lower with PEB versus PES (HR: 0.55, 95% CI: 0.28 to 1.07; p = 0.08), due to a lower risk of death (HR: 0.38, 95% CI: 0.17 to 0.87; p = 0.02). The risk of death/myocardial infarction was similar with PEB versus BA (HR: 0.96, 95% CI: 0.46 to 2.0; p = 0.91).ConclusionsAt 3 years, the use of PEB as compared with PES to treat patients with limus-eluting stent restenosis has similar efficacy and safety. PEB remains superior to BA. The sustained efficacy without trade-off in safety supports the role of PEB as treatment option for patients with drug-eluting stent restenosis.
