Abstract

Background: The tricuspid annular plane systolic excursion (TAPSE) is an echocardiographic measurement to assess right ventricular systolic function in adults and children. Objective: We determined growth- and birth weight-related changes of TAPSE to establish reference values in preterm and term neonates. Methods: A prospective study was conducted in a group of 258 preterm and term neonates (age: 25+0 to 40+6 weeks of gestation, birth weight: 530-4,200 g). Results: The TAPSE ranged from a mean of 0.44 cm (Z-score ±2: 0.30-0.59 cm) in preterm neonates in the 26th week of gestation to 1.03 cm (Z-score ±2: 0.85-1.21 cm) in term neonates in the 41st week of gestation. The TAPSE values increased in a linear way from the 26th to 41st week of gestation. TAPSE, week of gestation and weight are strongly correlated: Pearson's correlation coefficient was 0.93 for week of gestation - TAPSE (p <0.001), 0.93 for week of gestation - birth weight (p <0.001), and 0.89 for birth weight - TAPSE (p <0.001). There was no statistically significant difference of normal TAPSE values between female and male patients (p = 0.987). Conclusion: Z-scores of TAPSE values were calculated and percentile charts were established to serve as reference data for ready application in preterm and term neonates with structurally normal hearts and with congenital heart disease in the future.
