Abstract

Abstract: Tricuspid annular plane systolic excursion (TAPSE) is important in the noninvasive echocardiographic assessment of right heart function. This retrospective observational study shows correlations of TAPSE with invasive right heart catheterization parameters after pediatric heart transplantation (HTx). The study included patients after pediatric HTx with cardiac catheterizations in 2018/2019 and measurement of TAPSE ( n = 52 patients with 57 examinations; 50.9% adults, 52.6% female, median age: 18.54 years). TAPSE was compared with normal values. Stepwise, linear and multiple regression were used to show influencing variables on TAPSE. Mean TAPSE z‐score was −3.48 (SD: 2.25) and 68.4% of HTx‐recipients showed abnormally reduced TAPSE (z‐score ←2) compared to normal values. Multiple regression ( p ‐value <0.001; corrected R 2 = 0.338) showed significant correlations of time since HTx ( p ‐value <0.001) and mPAP ( p ‐value: 0.008) with TAPSE z‐scores. Divided into subgroups (time since HTx <10 and ≥10 years), TAPSE and mPAP correlated only ≥10 years after HTx ( p ‐value = 0.002). This study provides data of TAPSE even ≥10 years after pediatric HTx. Most patients showed a decreased TAPSE early after HTx, which improved over time. TAPSE z ‐scores correlated significantly with time since HTx and mPAP, especially ≥10 years post‐HTx. Therefore, TAPSE must be used carefully in the early follow‐up.
