Tricuspid annular plane systolic excursion and mitral annular plane systolic excursion cardiac reference values in 1300 healthy children: Single‐center results

Abstract Background Tricuspid annular plane systolic excursion (TAPSE) and mitral annular plane systolic excursion (MAPSE) are two echocardiographic parameters which provide reliable information about the longitudinal myocardial functions of the right and left ventricles in both adult and pediatric population. The aim of this study was to determine the TAPSE and MAPSE reference values in healthy children aged 0‐18 years. Methods and Results This prospective study included 1300 healthy children evaluated with two‐dimensional echocardiography. In addition to routine echocardiographic examination, the right and left ventricular systolic functions were assessed by TAPSE and MAPSE measurements. Statistical analyses were carried out in the groups of subjects stratified according to age and body surface area. The mean and standard deviation values and z‐scores of TAPSE and MAPSE were developed in each group. Conclusions The determination of reference values for TAPSE and MAPSE in healthy children will be of guidance in the evaluation of both healthy children and those with congenital or acquired heart diseases in which the right and left ventricular systolic functions are affected. The reference values obtained will contribute to the clinical practice and the future studies.
