ASTRO: Stereotactic Arrhythmia RT Safer Than Repeat Catheter Ablation for High-Risk Ventricular Tachycardia
For patients with ventricular tachycardia (VT), stereotactic arrhythmia radiotherapy (STAR) may be a comparable and safer alternative to repeat catheter ablation (CA).
A study presented at the annual meeting of the American Society for Radiation Oncology (ASTRO) found that STAR may be a viable option for patients with high-risk VT.
- Researchers reported three-year outcomes for patients treated with STAR versus CA for high-risk VT between 2015 and 2018.
- Patients were followed for serious adverse events (SAEs), overall survival (OS), and freedom from death, shock, or storm (FFDSS).
The study included 43 patients: 22 treated with STAR (18 failed prior CA) and 21 with repeat CA (all failed previous CA), as reported by Shannon Jiang, M.D., from the Washington University School of Medicine in St. Louis, and colleagues.
