Abstract

Abstract : Introduction: The justification as well as the benefit–risk ratio of interventional cardiology procedures (ICP) is well established. However, the increasing use of ICP in pediatric population stresses the need of setting up reference levels and keeping doses to children as low as possible. Purpose: The present study aims at evaluating radiation dose levels for the most frequent ICP performed in five French reference centers for complex congenital heart disease (CHD). Materials and methods: For nearly 4, 000 ICP performed among pediatric patients (age <16 years) over the period 2009–2013, the date of procedure, the age and weight of the patient were collected. Air kerma-area product (PKA ) and fluoroscopy time (FT) were retrieved retrospectively from automatic dose recording. The median, first and third quartiles, minimum and maximum values of PKA and FT were calculated according to patients' age and weight. Results: The main ICP investigated were: Diagnostic, Patent Ductus Arterious closure, Atrial Septal Defects closure, Valvuloplasty and Angioplasty. Preliminary results will be presented and discussed in the light of methodological limits and in comparison of available reference levels for ICP. Conclusion: This is the first study in France to focus on children undergoing ICP. In order to have a better evaluation of current practices in pediatric ICP at national level, this work will be extended to the whole French network for CHD. The present work is included in the framework of an epidemiological cohort study, named "Coccinelle" and specifically designed to evaluate long term cancer risks after ICP during childhood.
