Congenital heart defects are the most common chronic congenital anomalies in childhood. They occur as a consequence of the action of genetic and multifactorial factors. Feasibility is present in both sexes, regardless of the economic situation of the country. They lead to structural and functional changes in the heart muscle, thus interfering with its normal functioning. The most effective method of treating and solving the problem of heart defects is surgery. By being exposed to an invasive procedure, they encounter numerous postoperative risks, and it is necessary to provide maximum care and support. The formation of a care team, the application of the health care process, ensures adequate conditions during the stay in the tertiary level health institution.
