• Coronary Intravascular Brachytherapy for Recurrent Coronary Drug-Eluting Stent In-Stent Restenosis: A Systematic Review and Meta-Analysis

    Abstract

    Objective

    To examine the outcomes with intravascular brachytherapy (IVBT) in recurrent in-stent restenosis (ISR).

    Background

    Recurrent ISR can be challenging to treat and IVBT can be used for recurrent ISR but has received limited study.

    Methods

    We performed a systematic review and meta-analysis of five observational studies, including 917 patients (1014 lesions) with recurrent ISR, defined as having at least two prior ISR episodes with previous treatment with a stent, who underwent treatment with IVBT. Outcomes of interest included target vessel revascularization (TVR), myocardial infarction (MI), and all-cause mortality.

    Results

    During a mean follow-up of 24 ± 7 months, the incidence of TVR was 29.2% (95% CI 18.0–40.4%). The incidence of MI and all-cause mortality were 4.3% (95% CI 1.7%–6.9%) and 7.3% (95% CI 3.2–11.5%), respectively. At one- and two-years after PCI the incidence of TVR was 17.5% (95% CI 13.6%–21.4%) and 26.7% (95% CI 16.6%–36.9%), respectively and the incidence of MI was 3.1% (95% CI 2–4.2%) and 3.9% (95% CI 1–6.8%), respectively.

    Conclusion

    Intravascular brachytherapy can be used to treat recurrent ISR, although TVR is needed in approximately one of four patients at two years.
