Pediatric cardiac catheterization could be performed with low levels of radiation exposure using one center s as low as reasonably achievable (ALARA) protocol, researchers reported.
The strategy employed by Lisa Goto, MD, and colleagues at the Children s Hospital at Montefiore in New York City, resulted in favorable radiation levels across 95 catheterizations in 77 children weighing 20-40 kg (approximately 44-88 lbs):
Median fluoroscopy time: 11.9 minutes
Total air Kerma product: 38 mGy
Dose air product (DAP): 175 µGym

2/kg
Based on these findings, radiation exposure during cardiac catheterization with ALARA seems to compare favorably against published values, as Goto cited prior reports of air Kerma reaching 370-400 mGy and DAPs exceeding 2,000 µGym
