Background: The objectives of this study were to find out of normal reference value for age-dependent longitudinal strain values in children and find its correlation with conventional echocardiographic parameters. Methods: In total, 100 healthy normal children aged between 2 and 15 years were enrolled and divided into three age groups, namely, 2–5 years, 5–10 years, and 10–15 years. Using the GE Vivid 7 ultrasound platform with 4 or 7 MHz probes, both LV and RV global longitudinal strains and conventional echocardiographic parameters were acquired. Results: In normal healthy children, left ventricular GLS values were –20.10 to –19.68 (mean: –19.89), –21.93 to –21.02 (mean: –21.48), and –20.87 to –20.41 (mean: –20.64)) in children aged 2–5 years, 5–10 years, and 10–15 years and right ventricular GLS values were –16.80 to –16.44 (mean: –16.62), –27.85 to –27.27 (mean: –27.56), –28.44 to –27.93 (mean: –28.19) in the above three groups, respectively. No significant increase was noted in the left ventricular strain value from basal to the apical segment from age group 2 years to 15 years and no gender differences were seen. None of the conventional echocardiographic parameters commonly used to assess the left or right ventricular systolic function had a significant correlation with LVGLS and RVGLS. Conclusions: The mean LVGLS values were –19.89, –21.48, and –20.64 and RVGLS were –16.62, –27.56, and –28.19 in healthy normal children aged 2–5 years, 5–10 years, and 10–15 years, respectively, and conventional echocardiographic parameters did not have any significant correlation with these values.
