The reliability analysis of the artificial cardiac valve and experiments made it possible to establish that the ACV reliability is ensured by the physical and mechanical properties of the material, technology observance and thorough control over each operation during the manufacturing process. The accelerated testing of the new MX disk valve made in the USSR showed a satisfactory degree of the disk wear and the absence of breaks-down after 400 million working cycles which is equivalent to ten-years' work in a human body.
