title: [Reoperations in patients with EMIKS and LIKS prostheses].
abstract: The frequency, terms, techniques, and the results of reoperations on patients with EMIKS and LIKS prostheses are analysed. In the period between June, 1983 and December, 1989, 994 EMIKS prostheses and 210 LIKS prostheses were implanted in 1,015 patients. In this period 22 reoperations were performed which accounted for 0.62% of patients per year. The reasons for the repeated operations were prosthetic endocarditis in 54.5%, paraprosthetic fistula in 36.4%, and wedging of the disk of a mitral prosthesis in 9.1% of patients. In 81.8% of patients the second operation was conducted within the first year after the first operation. By the 6th postoperative year 96.4 +/- 0.61% of patients did not need a reoperation. This index was 97.1 +/- 0.54% in the group of patients with isolated mitral prosthetics, 95.7 +/- 0.88% in aortic prosthetics, and 94.9 +/- 0.91% in mitro-aortic replacement. Hospital mortality in the group of patients with reoperations was 22.7%.
