Outcome of Coronary Edge In-stent Restenosis Management by Restenting Versus Drug-Eluting Balloon

Abstract Background: The optimal therapeutic strategy for coronary intervention in edge in-stent restenosis (edge ISR) remains less well-defined. Aim: The aim of this study was to assess 12-month outcomes of re-stenting using drug-eluting stents (DESs) versus using drug-eluting balloon (DEB) for managing coronary edge ISR. Patients and Methods: One hundred and four patients with edge ISR were randomly assigned to either DES or DEB. The primary endpoint was stent failure at 12-month follow-up. Results: Significantly lower target vessel revascularization among the DEB group compared to restenting group, (7.7% vs. 23.1%, P = 0.04). Likewise, target vessel-related myocardial infarction rate was significantly lower among the DEB group than restenting (5.7% vs. 23.1%, P = 0.04). On the other hand, there were no significant differences in the rates of deaths or restenosis between the two groups. Conclusion: The DEB is superior to the DES with better both safety and efficacy.
