Clinical and instrumental assessment of the current congenital heart defect in early age children depending on the severity of arterial hypoxia

Congenital heart defects are the most common abnormalities in children and remain the leading cause of disability and mortality. The most common congenital heart defects in children are DMZHP, DMPP, and tetrad Fallot. The natural course of these defects is accompanied by the development of a number of severe complications, due to arterial hypoxia. High mortality in children with septal defects is due to congestive heart failure and pulmonary hypertension, in children with CHD of the blue type - diffuse hypoxemia. Low supply of arterial blood with oxygen causes severe clinical manifestations of the defect and contributes to the formation of heart rhythm disorders, which can serve as an additional risk factor in the prognosis of CHD.
