[Experience in the use of Soviet-made disk prostheses EMIKS and LIKS].

Experience in the application of and disc prostheses in 614 patients in generalized. Mitral prosthetics was conducted in 256, aortic in 229, and mitral++-aortic in 129 patients. Hospital lethality was, respectively, 3.9, 4.8, and 8.5%. In postoperative follow-up periods of up to 7 years 92.1% of patients were examined. Survival was 88.1 +/- 0.71% in the mitral, 87.0 +/- 0.62% in the aortic, and 80.2 +/- 0.84% in the mitral-aortic group. No thromboembolic complications occurred in 88.7 +/- 0.64%, 96.9 +/- 0.31%, and 88.3 +/- 0.68% of patients, respectively. In the mitral position the mid-diastolic gradient was 4.0 +/- 0.31 mm Hg on the prosthesis and 3.8 +/- 0.82 mm Hg on the prosthesis; in the aortic position the peak systolic gradient was, respectively, 23.2 +/- 0.58 and 22.4 +/- 0.7 mm Hg. At the time of examination 97% of patients belonged to I and II functional classes.
