Abstract
Objective To establish age-specific and body surface area (BSA)-specific reference values of Tricuspid Annular Plane Systolic Excursion (TAPSE) for children under 15 years old in China. Study design A retrospective study was conducted in Children's Hospital Attached to the Capital Institute of Pediatrics. A total of 702 cases were included in this research to establish reference values of TAPSE. SPSS 25.0 (IBM) was used for data analysis. Lambda-mu-sigma method was used to calculate and construct the age-specific and BSA-specific percentiles and Z-score curves of TAPSE. Results The mean value of TAPSE increased with age and BSA from 0 to 15 years in a nonlinear way and reached the adult level (17mm) until 1 year old. No difference could be observed in genders. Conclusions TAPSE values increased with age and BSA in Chinese children aged between 0-15 years and there was no difference between boys and girls. A multi-center study from different parts of China is supposed to be conducted in the future to reflect the whole spectrum of TAPSE in Chinese children.
