Despite the clear clinical benefit to the patient, the complexity of these procedures may result in high cumulative radiation exposure. Given children's greater sensitivity to radiation and the longer life span during which radiation health effects can develop, an epidemiological cohort study, named Coccinelle (Cohorte sur le risque de cancer après cardiologie interventionnelle pédiatrique) is being launched in France to evaluate the risks of leukaemia and solid cancers in this specific population. null France Individuals Patients population Male Female Infant, Newborn (birth to 28 days) Infant (28 days to 2 years) Child, Preschool (2 to 5 years) Child (6 to 12 years) The study population will include all children who have undergone at least one cardiac catheterization procedure since 2000 and were under 10 years old and permanent residents of France at the time of the procedure. Electronically stored patient records from the departments of paediatric cardiology of the French national network for complex congenital heart diseases (M3C) are being searched to identify the children to be included.
