[Results of laboratory and clinical tests on the new Soviet heart valve model 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.
