A trial of the use of EMIKS and LIKS disk prostheses over 10 years

: A total of 2575 EMIKS and LIKS prostheses were implanted to 2309 patients from January 1, 1983 to January 1, 1993. The results were assessed in 1349 patients with primary isolated prostheses of the mitral (PMV), aortic (PAV), and mitral and aortic (PMV + PAV) valves. Mitral valves were replaced in 592 patients, with hospital mortality 3.3%. Aortic valves were replaced in 463 patients, hospital mortality being 2.5. Both the valves were replaced in 289 patients, with hospital mortality 7.6%. A total of 91.8% of patients were examined in periods of up to 9 years after surgery; those were operated on before January 1, 1992. Survival rate by the 9th year postoperation was 88.9 +/- 0.75% of patients with PMV, 88.2 +/- 0.79% with PAV, and 82.1 +/- 0.82% with PMV + PAV. Prosthesis thromboses were observed in 0.05% percent/patient/years, thromboembolism in 1.09% percent/patient/year, prosthetic endocarditis in 0.52 percent/patient/year, paraprosthetic fistulae in 0.63 percent/patient/year. By the 9th year postoperation 86.9 +/- 0.61% of patients with PMV, 96.8 +/- 0.25% of those with PAV, and 88.7 +/- 0.64% of those with PMV + PAV were free from thromboembolic complications.
