70%) were involved in this study. Patients were assigned as intracoronary ?-radiation (Beta Cath 30 mm or 40 mm system, Novoste) with CBA group (n=112) and control group (n=183). Pullback radiation was performed for long ISR lesions. In the control group, the patients received intracoronary ?-radiation or CBA alone. In both groups, quantitative coronary angiography was performed, and target vessel revascularization (TVR) and major adverse cardiovascular events (MACE) were documented. Results Clinical follow-up (6.3?1.6 months) was conducted in 106 patients (95%) in the intracoronary ?-radiation with CBA group and 172 patients (94%) in the control group. In the follow-up, in the intracoronary ?-radiation with CBA group, MLD was larger and DS was lower than that in the comparison group. Both TVR and MACE occurred significantly less in the intracoronary ?-radiation with CBA group than in the control group (5% vs 16% for TVR, and 10% vs 25% for MACE; P
