[Changes of the volume of body fluids in cardiac insufficiency of patients with congenital heart defects].

Results consequent upon investigations into variations of the water metabolism, central and intracardiac hemodynamics and myocardial contractility in 42 patients with congenital heart defects are reported. It is established that an increase in the content of total water in the body and of the intracellular liquid may be considered to be a significant sign pointing to circulatory insufficiency, even in the absence of any clinical manifestations of this condition.

[Age-specific aspects of hemodynamic and morphological changes of the pulmonary vessels in tetralogy of Fallot].

The results of investigations of 50 patients with tetralogy of Fallot aged from 5 months to 15 years, made prior to surgery, and of 14 others, examined after palliative operations, furnished grounds for assessing hemodynamic and morphological changes in the pulmonary vessels as viewed in an age-specific aspect. The patients underwent catheterization of the heart, angiocardiography and histological investigation of the pulmonary tissue. In each age group the characteristics of the cardiac cycle in the right ventricle, minute volume and cardiac index, hemodynamic indices of the lesser circulation, pulmonary and greater circulation vessels resistance were analyzed. In the age category of up to 6 years the development of compensatory-adaptive reactions of the organism were recorded. The pressure in the pulmonary artery remained normal. Morphological alterations in the pulmonary arterial trunks were seen to occur already in the early childhood.
