Objective: Tricuspid annular plane systolic excursion (TAPSE) is an echocardiographic measurement used for evaluating right ventricular systolic function. While established reference values of TAPSE exist for the adult population, only a limited number of studies have attempted to evaluate reference values for the pediatric population. The aim of the present study was to determine the reference values for TAPSE in healthy children in Turkey.
Methods: A total of 765 healthy children aged between 0 and 18 years, all of whom were referred to our clinic with cardiac murmurs, were evaluated prospectively. Patients with no cardiac pathologies or other disorders were excluded from the study. The measurement of TAPSE was obtained using a 2D-guided M-mode technique with echocardiography, and the relationship between age and surface area with TAPSE was investigated. The statistical analysis was carried out using the SPSS 20.0 software package (SPSS Inc., Chicago, IL, USA, 2012).
Results: The mean TAPSE value was found to be 19.56±5.54 mm, and no significant difference was identified between male and female children. TAPSE values showed a positive correlation with increasing age and surface area. The mean TAPSE value was 9.09±1.36 mm in newborns and 25.91±3.60 mm in the 13-18 years age group. A negative correlation was seen between TAPSE and heart rate.
Conclusion: In the present study, the reference values for TAPSE in healthy Turkish children were presented in percentile tables and the corresponding z-scores were determined. These reference values may be useful in daily practice for the evaluation of right ventricular systolic function in children. (Anatol J Cardiol 2016; 16: 354-9)
