Dynamics of processes of left ventricle adaptation in children with aorta coarctation before and after surgical treatment

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.
