| Abstract: | At modelling a congenital heart failure--defect of the interatrial septum during late stages of the experiment, dilatation of the pulmonary artery and certain changes in the microcirculatory bed of the lungs, oesophagus, stomach and colon are observed. It has been demonstrated histologically and morphometrically that in adaptive reactions of the blood bed an important role belongs to the arteriolar part and metabolic link of the microcirculatory bed of the organs investigated. The changes in the pulmonary vessels are insufficiently expressed and possibility of hypertension in the lesser circulation is not great. |
