Why the study?
To study echomorphometric parameters in children with false tendons in the left cardiac ventricle to improve diagnostics of possible complications.
Do children with false tendons in the left ventricle have altered central hemodynamics compared to healthy children?
Do children with false tendons in the left ventricle have altered central hemodynamics compared to healthy children?
Children with false tendons in the left ventricle exhibit early signs of diastolic dysfunction despite normal systolic function, suggesting a need for monitoring to prevent progression.
Diastolic changes with false tendons are hypothesis-generating; longitudinal studies needed before clinical monitoring.
Aim: To study the echomorphometric parameters of the heart in children with false tendons (FT) in the left cardiac ventricle to improve diagnostics of its possible complications.Materials and methods. 64 children with FT, aged from 13 to 17 (15,3±0,2) years old, were examined. Main group of patients consisted of 40 (62,5±6,1%) boys and 24 (37±6,1 %) girls. The control group included 23 almost healthy children of similar age. The study was carried out in Vinnitsa city hospital "Center of Mother and a Child". The morphological and functional condition of the heart with hemodynamic parameters was evaluated according to the standard method, recommended by American association of cardiologists in one-dimensional (M-) and two-dimensional (B-) modes, using echocardiography with Doppler effect.Results. Echomorphometric indicators did not significantly differ from the control data. Indicators of ejection (69,4±0,8% vs. 67,8±1,7% – boys and 70,8±1% vs. 69±1,4% – girls) and shortening fraction of the left ventricle (38,6±0,8% vs. 41±2% – boys and 40,8±0,9% vs. 32,5±2,8% - girls) were within normal limits. There was a tendency for decreasing of the end-diastolic index (EDI) in both subgroups (60,3±2,7 ml/m² vs. 62,5±3,9 ml/m² – boys and 56,6±3,3 ml/m² vs. 68,2±5,3 ml/m² – girls). Analysis of diastolic function of the left ventricle (LV) in children of the main group revealed increasing of the E/A parameter in boys (2±0,1 vs. 1,8±0,1, p<0,05) and in girls (2,2±0,1 vs. 2±0,1, p<0,05). The thickness of the left atrium (LA) was not changed. These results reveal the first stages of diastolic dysfunctions of the LV myocardium. The systolic function of the myocardium was normal.Conclusions. Children with FT have normovolemic and eukinetic types of central hemodynamics. Diastolic function in children with FT has initial signs of impairment. These results will help to prevent complication occurrence and progression of diastolic dysfunction of myocardium in adolescents with false tendons by timely providing medical-preventative methods
