Evaluation of the fetal QT interval using non-invasive fetal ECG technology.

Non-invasive fetal electrocardiography (NI-FECG) is a promising alternative continuous fetal monitoring method that has the potential to allow morphological analysis of the FECG. However, there are a number of challenges associated with the evaluation of morphological parameters from the NI-FECG, including low signal to noise ratio of the NI-FECG and methodological challenges for getting reference annotations and evaluating the accuracy of segmentation algorithms. This work aims to validate the measurement of the fetal QT interval in term laboring women using a NI-FECG electrocardiogram monitor.

First-trimester cystic hygroma: relationship of nuchal translucency thickness and outcomes.

Objective: To estimate the relationship between nuchal translucency thickness and abnormal karyotype, major congenital anomaly, perinatal loss, and composite abnormal outcome in fetuses with first-trimester nuchal cystic hygroma.

Methods: We performed a retrospective cohort study of first-trimester fetuses with ultrasound-diagnosed nuchal cystic hygroma collected over a 10-year period.

Results: There were 944 first-trimester fetuses with nuchal cystic hygroma.
