Özet
To evaluate cardiac maturational and haemodynamic alteration in healthy newborns and
infants and determine reference values in this period using tissue Doppler, strain, and strain rate
echocardiography. Material and Methods: The study included 149 healthy subjects. Babies from 1 day to
3 months were selected from the well-baby nursery department, and infants were selected from paediatric clinics
during routine visits for health maintenance. Subjects were allocated to four groups: preterm (36–37 weeks,
n 5 32), term (Z38 weeks, n 5 32), 1 month of age (n 5 47), and 3 months of age (n 5 38). Standard
echocardiographic evaluations, pulsed wave Doppler, tissue Doppler echocardiography, strain, and strain rate
studies were applied by the same person using a MyLab50 echo machine. Longitudinal and circumferential
systolic strain and strain rate measurements were assessed by two-dimensional speckle-tracking echocardiography
in all subjects. Results: The longitudinal systolic velocity, strain, and strain rate values derived from left ventricle
apical four-, three-, and two-chamber images, and circumferential systolic velocity, strain, and strain rate values
derived from left ventricle short-axis images decreased from the base to the apex in all subjects (p , 0.001).
Conclusion: Significant cardiac haemodynamic alterations occurred during the newborn and early infancy periods
and were detected by tissue Doppler, strain, and strain rate echocardiography. Although two-dimensional
speckle-tracking echocardiography is useful and can produce improved, reliable results in clinical practice, it has
some limitations. Therefore, more studies on this issue are required.
