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.

Implication

Retrospective survey reveals significant dose differences in infants and supports future standards for safety.

Abstract

Weight-stratified institutional typical values revealed critical disparities, notably a five-fold higher dose for therapeutic procedures in infants <5 kg (4.07 vs 0.80 Gy·cm2). While weight predicts diagnostic dose, complexity drives therapeutic exposure. These benchmarks enable local optimization and support future National DRL development.
