- Abstract
- BACKGROUND: The seventh Committee on \"Biological effects of Ionizing Radiation\" (BEIR
VII, 2006) underlines \"the need of studies of infants who are exposed to diagnostic radiation
because catheters have been placed in their hearts\".
OBJECTIVE: To determine the Lifetime Attributable Risk (LAR) of cancer associated with the
estimated cumulative radiological dose in 59 children (42 males, age=2.8±3.2 years) with complex
CHD, and to assess chromosomal DNA damage after cardiac catheterization procedures.
METHODS: In all patients, the cumulative exposure was estimated as effective dose in
milliSievert (mSv), and LAR cancer was determined from BEIR VII report. In a subset of 18
patients (13 males, age: 5 2± 5.7 years) micronucleus (MN) as biomarker of DNA damage and
long-term risk predictor of cancer was assayed before and 2 hours after catheterization procedures.
Dose-area product (DAP; Gy cm2) was assessed as measure of patient dose.
RESULTS: The median life time cumulative effective dose was 7.7 mSv per patient (range 4.6-
41.2 mSv). Cardiac catheterization procedures and computed tomography were responsible for 95%
of the total effective dose. For a 1-year-old child, the LAR cancer was 1 in 382 (25th-75th percentiles
1 in 531-1 in 187) and 1 in 156 (25th-75th percentiles 1 in 239-1 in 83) for male and female patients,
respectively. Median MN values increased significantly after procedure when compared to baseline
(pre= 6 ? vs post= 9 ?, p=0.02). The median of DAP values was 20 Gy cm2 (range of 1-277 Gy
cm2).
CONCLUSION: CHD children are exposed to a significant cumulative dose. Both indirect cancer
risk estimations and direct DNA data emphasize the need for strict radiation dose optimization in
children. (literal)
