Paediatric cardiac catheterization radiation doses: a 6-year retrospective survey and typical values in a Mexican tertiary care center

Key Points

• This research aims to analyze radiation doses during pediatric cardiac catheterization and establish typical values for optimization.
• Conducted a 6-year retrospective survey in a Mexican tertiary care center.
• Analyzed weight-stratified radiation doses during diagnostic and therapeutic procedures.
• Compiled typical values and identified disparities in radiation exposure for different weight categories.
• Found a five-fold higher radiation dose for therapeutic procedures in infants under 5 kg.
• Identified that weight is a predictor for diagnostic radiation doses, while complexity affects therapeutic exposure.
• Established benchmarks that can aid in local optimization of radiation use.
