We examined 47 patients (30 men and 17 women), age from 23 to 72 years (average age (54.7±12.0) years) before and after surgical treatment of valve disease. In this research we analyzed complaints, results of
echocardiography, 6minutes walking test in patients with valvular heart disease before, 1 and 6 month after surgical treatment. We found relation between the type of valve disease, severity of complaints and dynamics of
echocardiographic indexes. Already in 6 months after valve replacement the sizes of left atrium diminished which was accompanied by the improvement of functional class of heart failure according to the result of
6minutes walking test.
