      Abstract

      It has been estimated that for adults, each hour of fluoroscopic imaging exposure carries a lifetime risk of developing a fatal malignancy of 0.1% and a risk of a genetic defect of 20/million births.4 Chromosomal damage has been seen following catheterization in pediatric patients,5 although to date no increase in the incidence of malignancies in children who have undergone cardiac catheterization has been reported.6 As these patients age, close surveillance will enhance our knowledge of the precise effects of radiation exposure. In the meantime, AZ digital technology provides a method of reducing exposure to infants with a slight reduction in image quality. Future software advances in the technique should enhance the image quality and potentially broaden its application to older patients.
