    Abstract:
    OBJECTIVES: The authors sought to evaluate the relative performance of a drug-eluting balloon (DEB) and a drug-eluting stent (DES) in patients with any (bare-metal or drug-eluting stent) in-stent restenosis (ISR). BACKGROUND: The treatment of ISR remains challenging in contemporary clinical practice. METHODS: In a multicenter randomized noninferiority trial, patients with any ISR were randomly allocated in a 1:1 fashion to treatment with a DEB (SeQuent Please paclitaxel-eluting balloon, B. Braun Melsungen, Melsungen, Germany), or a DES (XIENCE everolimus-eluting stent, Abbott Vascular, Santa Clara, California). The primary endpoint was noninferiority in terms of in-segment minimal lumen diameter (MLD) at 6-month angiographic follow-up. Secondary endpoints included angiographic parameters at 6 months and clinical follow-up up to 12 months. RESULTS: A total of 278 patients, of whom 56% had DES-ISR, were randomized at 8 sites to treatment with DEB (n = 141) or DES (n = 137). As compared with DEB, DES was associated with larger MLD and lower % stenosis immediately post-procedure (1.84 ± 0.46 vs. 1.72 ± 0.35; p = 0.018; and 26 ± 10% vs. 30 ± 10%; p = 0.03). Angiographic follow up was completed at 196 ± 53 days in 79% of patients. With respect to the primary endpoint of in-segment MLD at 6 months, DEB was noninferior to DES (DEB 1.71 ± 0.51 mm vs. DES 1.74 ± 0.61 mm; p for noninferiority <0.0001). Target vessel revascularization at 12-month follow-up was similar in both groups (DES 7.1% vs. DEB 8.8%; p = 0.65). CONCLUSIONS: In patients with ISR, treatment with DEB was noninferior compared with DES in terms of 6-month MLD. There were no differences in clinical endpoints, including target vessel revascularization up to 12 months. Therefore, use of a DEB is an attractive treatment option for in-stent restenosis, withholding the need for additional stent implantation.
