Anatomic/functional changes in left ventricle after aortal valve replacement

The paper presents the experience with the aortic valve replacement to 394 patients. Among them 311 male and 83 female patients aged from 10 to 78 years old. I groupaortal insufficiency (АН+КАН) - 229 (58,1%) patients, II group with aortal stenosis (АС+КАС) - 165 (41,9%) patients. All the patients underwent a routine examination that included chest X-ray study, ECG and 2D- Echo. According to the type of prosthesis the patients were divided into several subgroups: A - mechanic prosthesis 214 patients, B - biological prosthesis 47 patients. In order to value the dynamics of functional changes of LV was done comparative analysis of the basic morph-functional and hemodynamical indicators of LV in 7-15 days after operation. Analysing all the information taken from research we can conclude that better changes of the LV size, weight of miocard, reconstruction of functional changes MV, the size of LA occurred after mechanical prosthesis implantation. While biological prosthesis implantation we do not have significant decrease ejection fraction of LV, but in recent after operation period the increase of ascendance aortic occurred.
