Coronary Stent Restenosis

Keywords

Brief summary

The aim of this open label, randomized study is to compare the safety and efficacy of three different methods to handle coronary drug eluting stent (DES) in-stent restenosis (ISR). These are the: * Magic Touch - sirolimus coated balloon * Emperor - paclitaxel and dextran coated balloon * Xience - chromium-cobalt everolimus eluting stent

Interventions

PROCEDUREIntravascular management of prior implanted coronary drug eluting stent restenosis

Intravascular devices will be assessed for the management of prior implanted drug eluting stent restenosis management.
