Description:

Safety and effectiveness of Sr-90 beta radiation vs. placebo in de novo and restenotic lesions in native coronary arteries.

Hypothesis:

Can Sr-90 beta radiation prevent restenosis after angioplasty/stenting?

Study Design

Study Design:

Patients Enrolled: >1400
Mean Follow Up: 8 months

Patient Populations:
