Gamma-1: Five Year Follow-up • Among patients treated with gamma brachytherapy or placebo for in-stent restenosis in native coronary lesions, there were no statistically significant differences in MACE, TLR, or TVR at five-years. • The risk of recurrent MI tended to be higher among patients treated with gamma brachytherapy (p=0.06) • While there was a clinical benefit at 9 months for gamma brachytherapy, these five-year results demonstrate no significant benefit of gamma brahcytherapy consistent with a “late catch-up” or delay in restenosis among these patients.
