简要总结
The maximum efficiency of umbilical cord blood flow depends on a specific number of coils. With modern ultrasound techniques, investigators can now detect cord abnormalities even before birth. In recent years, there has been a renewed interest in the umbilical cord, and several articles have been published regarding the number of coils.In this study, the relationship between the umbilical cord coiling index and fetal cardiac functions was evaluated.

结局指标
主要结局
The correlation between the fetal umbilical cord coiling number and the concurrently performed fetal echocardiography findings.
时间窗: The correlation between the fetal umbilical cord coiling index and the echocardiographic findings of the fetus within the first hour will be investigated.
This study will be a single-center study conducted on two hundred randomly selected pregnant women with uncomplicated singleton pregnancies in the late second trimester (20-24 weeks) who visit our hospital's perinatology outpatient clinic for routine prenatal check-ups. The umbilical cord coiling number and fetal cardiac function measurements will be performed within one hour by the same maternal-fetal medicine specialist.To optimize the quality of Doppler waveforms when assessing vascular structures, measurements will be obtained in the absence of uterine contractions and fetal activity, with an insonation angle as close to zero as possible and less than 30.Three parameters will be used to assess cardiac function: 1. Diastolic function 2. Systolic function 3. Both systolic and diastolic function
