We determined growth‐related changes in Sm to establish reference values for the entire pediatric age group.</p> </sec> <sec id="echo12541-sec-0002" sec-type="section"> <title>Methods and Results</title> <p>A prospective study was conducted in a group of 690 healthy pediatric patients (age: 1 day–18 years). We determined the effects of age, sex, and body surface area (BSA) on the Sm values. Regression analysis was used to estimate Sm from age, BSA, and sex. In addition, a correlation of normal Sm with normal age‐matched values of the M‐mode parameter mitral annular plane systolic excursion (MAPSE) was measured. The Sm ranged from a mean of 5.8 cm/sec (Z‐score ±2: 3.6–8.0 cm/sec) in the newborn to 11.8 cm/sec (Z‐score ±2: 8.5–15.1 cm/sec) in the 18‐year‐old adolescent. The Sm values showed a positive correlation with age and BSA with a nonlinear course. There was no significant difference in Sm values between females and males. A significant correlation was found between Sm and MAPSE values.</p> </sec> <sec id="echo12541-sec-0003" sec-type="section"> <title>Conclusion</title> <p>Z‐scores of Sm values were calculated and percentile charts were established to serve as reference data in patients with congenital heart diseases.</p> </sec> </abstract>
