| Sumario: | Echocardiographic measurement of left ventricular mass (LVM) is being used for the diagnosis of left ventricular hypertrophy in children with various cardiovascular diseases. The purposes of this study was to establish normal values of LVM according to weight, height and body surface area (BSA) in children and to determine the sex differences. We evaluated 208 children (143 males and 65 females), aged 1 day to 14 years who had no cardiovascular disease. The end-diastolic left ventricular internal dimension (LVIDd), end-diastolic left ventricular posterior wall thickness (LVPWd) and end-diastolic interventricular septum (IVSd) values were determined by M-mode echocardiographic examination. By using these values, left ventricular mass was calculated. The difference between LVIDd, LVPWd and LVM values of boys and girls were not statistically significant . We observed statistically significant differences between the sexes relative to IVSd and LVM/BSA values. The left ventricular mass and its components presented a good correlation with age, weight, height and BSA. The study let us know the lower and upper limits of cardiac dimensions and LVM obtained by echocardiography in normal Turkish children according to BSA. Also, as the LVM/BSA values show gender difference in children, sex should be taken in consideration while evaluating the left ventricular hypertrophy. |
