ClinConnect Summary

This is a multicenter, prospective, randomized, open study

After the permeabilization of the clinical event responsible artery and the insertion of a bare metal stent, patients will be randomized in a 1:1 ratio to one of the following treatment groups:

Group 1: post-dilatation with a paclitaxel eluting balloon (Pantera Lux ®) Group 2: no post-dilatation Patients (or their legal representative) must sign the consent before randomization.

After surgery, patients will be treated with dual antiplatelet therapy (aspirin plus clopidogrel) for at least one month to group 2 patients; and at leas...
