[Hydrodynamic criteria in the choice of surgical tactics in implanting pulmonary artery trunk prosthesis].

The paper is concerned with the present-day problem of modern medicine, namely with surgical correction of the diseases of the initial part of the pulmonary circulation. The authors suggest hemohydrodynamic simulation of the right heart complicated by extracardial conduit. The simulation was performed at the high theoretical, practical and methodological level to obtain highly significant information which is likely to have paramount importance for clinical practice.

[Flow structure in artificial heart ventricle].

The flow structure in the artificial heart ventricle has been investigated by laser knife visualization method using fluorescence. It is shown that the flow structure is essentially three-dimensional. The effect of inlet artificial valve orientation on the flow structure is demonstrated. The artificial ventricle elastic cover deformation process is reviewed.

[Comparative hydrodynamic evaluation of variants of the cavopulmonary anastomosis].

An analysis of the range of postoperative complications following cavapulmonary anastomosis reveals a number of medical engineering problems in surgery techniques. The severity of the surgery due to the nonphysiological rearrangement of blood circulation makes it necessary to search for the most optimal types of anastomosis in terms of the hemo- and hydrodynamics of circulation. To optimize the performance of cavapulmonary anastomosis, namely to define the mutual localization and orientation of the implanted anastomoses against the axes of inflow and outflow, hemo- and hydrodynamic studies were made by Doppler laser anemometry. From the hydrodynamic point of view, the findings indicate the most optimal type of cavapulmonary anastomosis-cruciform anastomosis by displacing 0.5 d from the outflow axis at an angle of 60ë5 degrees.
