Although radiation exposure is potentially carcinogenic, there are limited data on cumulative exposure and the associated cancer risk.

Exposure to radiation-producing examinations was tabulated, and cumulative effective dose was calculated in millisieverts. These data were used to estimate lifetime attributable risk of cancer above baseline using the approach of the Committee on Biological Effects of Ionizing Radiation VII. The cohort included 337 children exposed to 13 932 radiation examinations. Conventional radiographs represented 92% of examinations, whereas cardiac catheterization and computed tomography accounted for 81% of cumulative exposure. Overall median cumulative effective dose was 2.7 mSv (range, 0.1\u201376.9 mSv), and the associated lifetime attributable risk of cancer was 0.07% (range, 0.001%\u20136.5%). Median lifetime attributable risk of cancer ranged widely depending on surgical complexity (0.006%\u20131.6% for the 7 surgical cohorts) and was twice as high in females per unit exposure (0.04% versus 0.02% per 1-mSv effective dose for females versus males, respectively;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Overall radiation exposures in children with heart disease are relatively low; however, select cohorts receive significant exposure.
