Abstract
The results of echocardiographic study of 87 children with coarctation of aorta before and after surgical treatment are presented. All children were broken down in two groups: patients with a low ejection fraction and those with a normal one. While determining the type of left ventricle remodeling, eccentric hypertrophy was revealed in 46% of patients in the first group, mainly in children with a preductal variant of aorta coarctation. It was found out that the echocardiographic characteristics of the first group patients, who underwent surgery at the age of more than 6 months, were restored slowly. In general, LV functional characteristics were restored faster than the geometrical ones. When studying a longitudinal function of the left ventricle, an increase in the index of myocardial contractility and a decrease in the myocardial rates in 100 % of cases were revealed.
