Abstract
Objective: The evaluation of right ventricular systolic function is an established component of echocardiographic examinations. The aim of the present study is to determine tricuspid annular plane systolic excursion (TAPSE) and cardiac z scores among a large cohort of healthy Turkish children. Material and Methods: This prospective study included 827 healthy children, ranging in age from 0 to 17.5 years (mean 6.04±4.98). Right ventricular systolic function was examined by TAPSE during a routine echocardiographic examination. Results: The mean TAPSE was 17.44±4.15 mm and the mean indexed TAPSE (TAPSE/m2) was 25.34±11.01 mm/m2. The mean TAPSE z- score and the mean TAPSE/m2 z score were -0.062 and 0.229, respectively, across all age groups. TAPSE, minimum, maximum, standard deviation, TAPSE/m2 ve percentile values were specified according to age groups and body surface area. Conclusion: The TAPSE, TAPSE/m2 and z-score values reported in the present study represent the first comprehensive set of reference values in the Turkish pediatric population. This study will inform future studies and clinical evaluation of both healthy children and children with congenital heart disease affecting right ventricular systolic function.
