Exploring the Application of Dual‐Gate Doppler Technology in Evaluating the Fetal Cardiac Global Function of Gestational Diabetes Mellitus

Pregnant women with GDM will cause an increase in the Tei index of the fetal left global cardiac function, indicating that the intrauterine hyperglycemic environment can cause damage to the global fetal cardiac function. The global fetal cardiac function was impaired in both the well-controlled and poorly controlled GDM groups, suggesting that early detection of GDM and the fetal cardiac dysfunction caused by GDM are necessary. The measurement of the Tei index of the left heart in the fetus using dual-gate Doppler technology can help detect the fetal cardiac dysfunction caused by GDM at an early stage, while the application of dual-gate Doppler technology in the overall cardiac function of the right heart still faces significant challenges.
