Abstract:
Objective:To evaluate the elastic characteristics of the pulmonary trunk and its distal branches in fetuses with tetralogy of Fallot（TOF）by Doppler echocardiography.Methods:A total of 42 fetuses with TOF（TOF group）and 84 gestational age-matched normal fetuses（control group）were prospectively collected from the Second Xiangya Hospital of Central South University from August 2022 to January 2023. The severity of TOF was classified into mild TOF（Z-score≥-2），moderate TOF（-40.05）. Conclusions:Fetuses with TOF present with increased MPA-PAS and decreased stiffness in the distal PA. Histological abnormalities of the pulmonary artery wall in fetuses with TOF have been observed during pregnancy.
