Echocardiographic assessment of the structural and functional properties of the left ventricle in children with hypertrophic cardiomyopathy

Aim. Analysis of the structural and systole-diastolic characteristics of the left chambers of the heart in children with obstructive hypertrophic cardiomyopathy. Materials and methods. A comprehensive retrospective comparative echocardiographic study of children with obstructive HCM aged 1–17 years (n = 52) and a control group (n = 1060) of healthy children of the same age was performed. Results. The main indicators of the structural and systole-diastolic properties of the left chambers of the heart in children of two groups were analyzed. In addition, in patients with HCM, the correlation between parameters of systolic and diastolic function of the left ventricle and the thickness of the interventricular septum was assessed. Most of the indicators characterizing the systolic properties of the LV had no correlation with an increase in the thickness of the IVS. Diastolic parameters – the rate of myocardial relaxation during the rapid filling phase, determined by tissue Doppler mode (e), and LV filling pressure – statistically significantly correlated with an increase in IVS thickness. Conclusions. Echocardiography in children with obstructive HCM remains the gold standard for diagnosis, allowing a comprehensive assessment of the main structural characteristics of the heart chambers.
