[Surgical correction of aortic valve disease with various types of prostheses].
Aortic valve replacement was carried out 394 patients. Among them 311 patients were men, 83 - women. Age of the patients varied from 10 to 78 years; mean age amounted 36.9+/-1.3 years. The patients were divided into 2 groups. 165 (41.9%) patients with aortic stenosis and combined aortic valve disease with predominance of stenosis formed the 1st group. 229 (58.1%) patients with aortic insufficiency and combined aortic valve disease with predominance of insufficiency formed the 2nd group. Mechanical valve prosthesis was applied in 224 patients, biological valve prosthesis - in 47 patients. Functional changes in left ventricular dynamics were evaluated in terms from 7 to 15 days after the operation. Received data show that implantation of mechanical valve prosthesis provides for optimal changes of left ventricular, myocardial mass and leads to functional recovery of mitral valve and left atrium. Significant increase of left ventricle ejection fraction was not observed after the implantation of biological valve prostheses; on the contrary ascending aorta size increases in early postoperative period.
