Current guidelines of the European Society for Clinical
Nutrition and Metabolism (ESPEN) and the European
Society of Paediatric Gastroenterology, Hepatology and
Nutrition (ESPGHAN) do not provide criteria for assessment
of malnutrition or of malnutrition risk in pediatric patients
(47). Studies are required to elaborate a simple, fast, and
specific clinical tool for the evaluation of the nutritional risk
of children with CHD.
