Abstract

Tissue Doppler echocardiographic imaging (TDI) is a novel method for accurately evaluating ventricular function. Currently, scant data are available on the distribution of tissue Doppler indexes in healthy children in the age range of 1 to 18 years. The aims of this study were to assess the distribution of tissue Doppler indexes of systolic and diastolic ventricular function in healthy children, to assess the influence of age on these indexes, and to compare them with conventional Doppler indexes. A total of 151 consecutive children aged 1 to 18 years were enrolled in the study. Nine different (7 diastolic and 2 systolic) TDI parameters were assessed. Peak velocities of systolic and diastolic excursions of the mitral and tricuspid annuli were obtained from the apical 4-chamber view. Mean velocities of early diastolic recoil of mitral and tricuspid annuli were measured from the apical 4-chamber view. The mean velocity of early diastolic relaxation of the left ventricular posterior wall was measured in the parasternal long-axis view. Results showed a statistically significant difference in some of the TDI indexes among the different pediatric age groups. Most of the TDI indexes showed a very weak correlation with age. There was no significant correlation (p >0.05) between peak velocities of the early diastolic mitral inflow Doppler pattern (E wave) and the corresponding TDI index. In contrast, there was a significant (p <0.001) correlation between the corresponding Doppler indexes in the tricuspid annulus. We conclude that TDI is a valuable tool for assessing ventricular function, particularly diastolic function. Establishment of normative data for TDI in the pediatric age group should broaden the clinical applicability of this useful modality for assessing ventricular function.
