Systolic Parameters
The systolic dysfunction results in a prolongation of IVCT by TDI with preserved EF/SF [13]. In our study we did not find significant difference in the values of MAPSE, TAPSE, LVEF, LVSF, which are systolic parameters, between groups in fetal and neonatal periods. However, IVCT values of RV TDI of neonatal and infant period were significantly higher. But LVEF, LVSF are significantly lower in infant period at normal range. Impaired ventricular compliance and persisting myocardial dysfunction with hypertrophy may repress the LV systolic functions on the long term.
