[Electroencephalographic and neurodevelopmental disorders in severe congenital heart disease: A follow-up study].

Congenital heart defects are the most common malformations at birth. Due to the fact that the developmental windows at early stages close rapidly, the aim of this study was to determine the impact of congenital heart defects on the central nervous system at short and medium terms after applying traditional and quantitative electroencephalography techniques and a test of neurodevelopment.
