Abstract

Objectives: This study sought to compare the long-term safety and efficacy of drug-eluting balloons (DEB) and everolimus-eluting stents (EES) in patients with in-stent restenosis (ISR) of drug-eluting stents (DES).

Background: Treatment of patients with DES-ISR remains a challenge.

Methods: The RIBS IV (Restenosis Intra-Stent of Drug-Eluting Stents: Drug-Eluting Balloons vs Everolimus-Eluting Stents) trial is a prospective multicenter randomized clinical trial comparing DEB and EES in patients with DES-ISR. The pre-specified comparison of the 3-year clinical outcomes obtained with these interventions is the main objective of the present study.

Results: A total of 309 patients with DES-ISR were randomized to DEB (n = 154) or EES (n = 155). At angiographic follow-up, the in-segment minimal lumen diameter was larger in the EES arm (2.03 ± 0.7 mm vs. 1.80 ± 0.6 mm; p < 0.01). Three-year clinical follow-up was obtained in all enrolled patients (100%). The combined clinical outcome measure of cardiac death, myocardial infarction and target lesion revascularization was significantly reduced in the EES arm (19 [12.3%] vs. 31 [20.1%]; p = 0.04; hazard ratio: 0.57 [95% confidence interval: 0.34 to 0.96]), driven by a lower need for target lesion revascularization (11 [7.1%] vs. 24 [15.6%]; p = 0.015; hazard ratio: 0.43 [95% confidence interval: 0.21 to 0.87]). The need for "late" (>1 year) target lesion revascularization (2.6% vs. 4%) and target vessel revascularization (4% vs. 6.6%) was similar in the 2 arms. Rates of cardiac death (3.9% vs. 3.2%), myocardial infarction (2.6% vs. 4.5%), and stent thrombosis (1.3% vs. 2.6%) at 3 years were also similar in both arms.

Conclusions: The 3-year clinical follow-up of this randomized clinical trial demonstrates that in patients with DES-ISR, EES reduce the need for repeat interventions compared with DEB.
