Abstract

Since the introduction of 3D mapping systems, the use of x-rays in electrophysiology
procedures has significantly decreased. The goal of this study was to analyze the frequency of x-ray
use in pediatric electrophysiology in relation to age or body mass, indication for the procedure, and
arrhythmia substrate. Th is retrospective, cross-sectional study included all pediatric procedures in two
centers, Gottsegen Cardiovascular Center, Budapest, Hungary and Sestre milosrdnice University
Hospital Center, Zagreb, Croatia. Patient data included weight, age, sex, presence of structural heart
disease, indication for the electrophysiology study, arrhythmia substrate, and x-ray use. A total of
914 participants were analyzed, mean age 13.25 years and mean mass 53.20 kg. Of all procedures,
62.04% were performed without and 37.96% with fluoroscopy. Th ere were no statistically significant
differences in the frequency of x-ray use when comparing the groups by sex (p=0.181), age (p=0.380)
or mass (p=0.120). Left-sided accessory pathways required x-ray use most frequently, whereas
unknown substrates and of the known substrates atrioventricular nodal reentry tachycardia required
it least frequently (p<0.001). Younger or smaller children were not irradiated more frequently during
electrophysiology procedures performed with 3D mapping systems. In conclusion, there is no reason
to postpone the procedure based on radiation frequency use.
