Outcome of Coronary Edge In-Stent Restenosis management by re-stenting versus Drug Eluting Balloon

Abstract Background: The optimal therapeutic strategy for coronary intervention in edge instent restenosis remains less well defined.Aim: To assess 12 months outcome of the Drug–eluting stent Versus Drug-Eluting balloon for managing coronary Edge In-stent restenosis. Methods:75 patients referred for coronary intervention with edge instent restenosis (edge ISR) were randomly assigned to either Drug eluting stent (DES)or Drug eluting balloon (DEB). The primary endpoint was target vessel revascularization (TVR) at 12 months follow up.Results: significantly lower TVR among the DEB group (0% versus 12.5%, P=0.048). Likewise, Target vessel related myocardial infarction rate was significantly lower among the DEB group (23.1 % versus 1.8 %, P< 0.05). On the other hand; there were no significant differences in the rates of deaths or restenosis between the two groups.Conclusion: The Drug eluting balloon is superior to the Drug eluting stent in management of edge restenosis with better both safety and efficacy.
