INFLUENCE OF IMPLANTATION OF MECHANICAL AND BIOLOGICAL PROSTHESES ON THE REMODULING OF THE LEFT VENTICLE IN PATIENTS WITH AORTAL VALVE STENOSIS

Objectives. To estimate influence of various artificial limbs on dynamics of indicators of the left ventricle (LV) in the postoperative period in patients with aortic stenosis.
Methods. In 394 patients prosthetics of the aortic valve was done including 311 males, 83 females, at the age from 10 till 78 years, an average age was 36,9±1,3 years. Aortic stenosis was observed in 165 (41,9 %) patients. From them mechanical valves were implanted in 139 patients, biological – in 26. Dynamics of functional changes of LV after operation in terms from 7 till 15 days was estimated.
Results. In patients with aortic stenosis a positive dynamics occurs basically at the expense of reduction of systolic size and volume of LV. A positive dynamics is noted at prosthetics both mechanical and biological valve; an authentic dynamics of the regression of the LV myocardium weight is noted.
Conclusions. In patients with aortic stenosis the implantation of two-folding mechanical valve leads to the best anatomic-hemodynamic changes of the LV indicators in the postoperative period.
