[Outcomes of reoperations in dysfunction of mechanical prostheses in relation to the clinical course].

Operations were conducted for the second time on 87 patients (98 operations). Reoperations were performed on 75 (76.5%) and closure of the fistula in 23 (23.

[Long-term results of mitral valve prosthetics depending on the prosthesis model (ball, disk)].

The authors conducted a comparative analysis of patients of 2 groups--with a MK4 model ball prosthesis and an folding disc prosthesis. It was found that the number of late-term (repeated) thromboembolic complications was significantly less in patients with a disc prosthesis (3.95 cases per 100 patient-years) and 4.

[Analysis of results of surgical treatment of patients with infectious endocarditis].

The results of surgical treatment of 180 patients were studied according to the character of infectious endocarditis (primary--PIE and secondary--SIE), the functional class (FC) in the preoperative period, and the patients' immune status. The survival of patients with PIE (with hospital mortality taken into account) was somewhat higher than that of patients with SIE. Survival in the late-term periods was significantly higher in patients with PIE.

[Evaluation of late results of aortocoronary bypass in patients with ischemic heart disease in relation to the bypass function].

The authors analyse 82 patients with aggravation of their clinical condition in the late-term periods after aortocoronary shunting. All were subjected to coronaroshuntography 3.6 +/- +/- 0.

[Dynamics of clinical and functional parameters in patients with ischemic heart disease after aortocoronary bypass surgery].

Complete myocardial revascularization was examined for effects on long-term results of aortocoronary bypass surgery in 219 patients. Myocardial revascularization was proposed to be divided into: (1) truely complete; (2) tentatively complete; and (3) partial. Clinical and functional parameters deteriorated in tentatively complete and partial myocardial revascularization as compared with truely complete revascularization.
