Overtime, there is a gradual attrition in patency requiring repeat intervention; Copyright c 2016 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved; METHODS: Patients undergoing VBT for recurrent DES-ISR were enrolled from a percutaneous coronary intervention registry. Clinical, procedural, VBT, and outcome data were collected for DES-ISR treated with radiation. Follow-up was obtained by phone call and clinic visits; OBJECTIVES: The study sought to report safety and long-term clinical efficacy of intravascular brachytherapy (VBT) for recurrent drug-eluting stent in-stent restenosis (DES-ISR); RESULTS: A total of 186 patients (283 lesions) were included. Mean age was 65 +/- 11 years, and 115 (61.8%) were men. Mean time to failure from last failed DES implantation was 450.65 +/- 50 days. Majority (95%) had >2 episodes of target lesion revascularization (TLR). Commonest presentation of DES-ISR was unstable angina (68, 30%). All lesions were treated with balloon angioplasty followed by VBT using Beta-Cath system (Best Vascular Inc., Springfield, Virginia) with a dose of 23 to 25 Gy at 2 mm from source center. Radiation was delivered to site of ISR, without procedural adverse events, in 99% cases. Incidence of TLR was 3.3% at 6 months, 12.1% at 1 year, 19.1% at 2 years, and 20.7% at 3 years. No subacute thrombosis event was noted. One patient had late thrombosis during a 3-year follow-up UR - https://dx.doi.org/10.1016/j.jcin.2016.03.018 ER -
