It has been shown that Bionics prostheses compare very favorably with bioprostheses based on rigid supporting frameworks. The advantages of the above prostheses lie in the fact that the supporting frameworks of changed stiffness used in their modelling possess damping capacities at minute physical loadings, which considerably improves the hydrodynamic characteristics of biovalves.

[Results of laboratory and clinical tests on the new Soviet heart valve model LIKS-2]. / Rezul'taty laboratornykh i klinicheskikh ispytanii novykh otechestvennykh klapanov serdtsa modeli LIKS-2

LIKS-2 rotatable disk prostheses were tested in laboratories for wear, atraumatic performance, and hemodynamic efficacy. Accelerated tests on testing units demonstrated their high reliability and lasting performance. The values of drops in, pressure and regurgitation volumes were negligible. The late-term results (of up to 5 years) of using LIKS-2 prostheses for correcting mitral and aortic valvular diseases were studied in the department of heart surgery of the All-Union Scientific Centre of Surgery. The prostheses showed high thrombo-resistance, mechanical reliability, and atraumatic performance in patients in the late-term follow-up periods.
