This thesis deals with the nursing and counselling of children with congenital heart defects and their relatives. Due to the heart disease of the child, relatives often experience severe emotional strain. However, this does not only a negative impact on the quality of life of the relatives themselves, but also on the child’s perception and coping with the disease. The central question is how far the higher service of health care and nursing can counteract existing and potential strains. Special attention is given to the counselling and guidance of relatives for nursing care. In this way, an intact parent-child relationship can be established and the development of the heart-affected child influenced in a positive way. The issue is treated on the basis of the selection, analysis and interconnection of recent scientific literature. The results show that the family's involvement in care, despite the congenital heart defect, is very important for the child as well as for the relatives.
