Aim. The paper aims to assess the quality of life of patients subjected to aortic valve replacement with a stented/stentless biological prosthesis. Methods. The research was done at the Acquired Heart Disease Department of Meshalkin National Medical Research Center. The inclusion criteria were patient age older than 65 years and severe stenosis of the aortic valve. 114 patients were randomized 1:1 in two groups: group I patients received stentless biological prostheses, while group II patients — stented xenopericardial ones. All patients underwent aortic valve replacement under normothermic cardiopulmonary bypass. Mean follow-up was 3.9 [2.77; 4.55] years, mean age 71.5±4 (65–84) years, mean left ventricle ejection fraction 65.5 (40–86) % and mean preoperative Log.Euroscore 5.4±1.3 (1.4–12.4). The quality of life was assessed by using a standard questionnaire SF-36. Results. Peak transprosthetic gradients at 1-year follow-up amounted to 16.22±4.34 and 24.66±4.74 mm Hg for group I and group II respectively. The 5-year survival rate was 90 [81; 99] % and 96 [90; 100] % for the two groups respectively and did not differ statistically (log rank test, p = 0.226). A statistically significant improvement of quality of life among patients in both groups was observed at 1-year follow-up, as compared to the preoperative values, however, marked intergroup differences in any of the parameters were not recorded. Conclusion. The quality of life after aortic valve replacement with stented and stentless biological prostheses in elderly patients confirms clinical and functional efficiency of both methods, does not show sound advantages of any of them and improves both the physical component of health and subjective emotional level.
