Objective. To determine the possibilities of tissue dopplerography in the evaluation of ventricular longitudinal diastolic function of heart.
Material and methods. In total 108 healthy newborns were examined with a definition of designated age-related values.
Results. The analysis of the velocity and time parameters of the fibrous ring motion of the mitral and tricuspid valves, according to pulsed-wave tissue Doppler mapping data, in newborns during the early neonatal period, showed no significant differences. When compared with similar parameters in adults, the significant differences (p<0.05) were revealed. In newborns, the studied quantitative parameters were lower, which may be due to the peculiarities of the neonatal myocardium structure.
Conclusions. The evaluation of diastolic function of the ventricles in neonates should be comprehensive, with the use of all possible Doppler regimes and the detection of speed and time parameters. Tissue dopplerography extends the ability to diagnose myocardial dysfunction at the preclinical stage.
Key words: tissue dopplerography, diastolic function, newborns, neonatal period.
