  Purpose

Treatment of patients with bare metal stent restenosis remains a challenge. This study will assess which interventional strategy (paclitaxel-eluting balloon vs everolimus-eluting stent) is superior in the treatment of patients suffering from bare metal stent restenosis.

Primary Outcome Measures:
  • Minimal lumen diameter [ Time Frame: Late angiographic follow-up (6-9 months) ] [ Designated as safety issue: No ]
    Comparison of minimal lumen diameter at late angiographic follow-up (6-9 months) between the 2 treatment strategies (by quantitative coronary angiography)


Secondary Outcome Measures:
  • Combined clinical and angiographic end-points [ Time Frame: 6-9 months, 1 year and 3 years ] [ Designated as safety issue: Yes ]

    A) Efficacy outcomes:

    A1) Angiographic: 1) Restenosis rate, 2) % diameter stenosis, 3) acute gain, 4) late loss, 5) net gain A2) Composite of death, myocardial infarction, target vessel revascularization and analysis of individual events

    B) Safety Outcomes: Stent thrombosis, Bleeding episodes.

    C) Pre-specified variables for subgroup analysis (RIBS I)

    D) Stratification (length and edge). Type of stent

    E) Influence of clinical variables and restenosis patterns on outcome

Detailed Description:

Treatment of patients with bare metal stent restenosis remains a major clinical and technical challenge. Currently, drug-eluting stents are widely used in the management of these patients. Recently, the value of the paclitaxel-eluting balloon in this clinical setting has been suggested. However, there is only scarce observational data on the value of this new balloon in patients with bare metal stent restenosis.

This prospective, multicenter, randomized clinical trial will compare two different interventional strategies (namely, paclitaxel-eluting balloon vs everolimus-eluting stent) in the treatment of patients with bare metal stent restenosis.
