Brief summary

Treatment of patients with drug-eluting 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 drug-eluting stent restenosis.

Detailed description

Treatment of patients with drug-eluting 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 drug-eluting 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 drug-eluting stent restenosis.
