Orlando, Fla—Radiation therapy cannot be recommended to prevent restenosis caused in patients undergoing coronary angioplasty or stenting for de novo lesions, Richard E. Kuntz, MD, told participants in the American College of Cardiology's Annual Scientific Session. Kuntz, lead investigator of the Beta-Cath System Trial, is with the Division of Clinical Biometrics at Brigham and Women's Hospital in Boston.
Kuntz said he was surprised at the outcome of the study and hypothesized that the negative results were caused by poor radiation and stenting procedures—and not by some basic flaw in the theory of radiation's benefits.
