Abstract
The valve functions of heart (in norm and pathological state) and hemodynamic characteristics of mechanical prosthetic cardiac valves influencing hemolysis and blood coagulation have been investigated. The computer and physical models of the disc cardiac valve implant have been constructed. The analysis of blood velocity and pressure at direct and inverse blood flows has shown better characteristics of butterfly valves. An advantage of this approach is in thorough description of blood flow assisting in determination of turbulence and depression zones for different size, curvature and ultimate opening angle of the leaves. This minimises hydraulic resistance, thrombus formation and hemolysis thus preserving high reliability of valve closing. A design of the valve prosthesis aimed at improving valve functions by swirling the blood flow is discussed.
