Fetal Electrophysiologic Abnormalities in High-risk Pregnancies Associated With Fetal Demise
Medical College of Wisconsin
Summary
Each year world-wide, 2.5 million fetuses die unexpectedly in the last half of pregnancy, 25,000 in the United States, making fetal demise ten-times more common than Sudden Infant Death Syndrome. This study will apply a novel type of non-invasive monitoring, called fetal magnetocardiography (fMCG) used thus far to successfully evaluate fetal arrhythmias, in order to discover potential hidden electrophysiologic abnormalities that could lead to fetal demise in five high-risk pregnancy conditions associated with fetal demise.
Description
Fetal demise occurs in over 25,000 pregnancies annually in the US and over 2.5 million in pregnancies worldwide. Certain maternal-fetal-placental abnormalities can have a high risk of fetal demise. Despite advances in fetal surveillance with ultrasound and cardiotocography, the reduction in fetal mortality lags behind that of the neonate and has shown little decline in the past decade. This suggests that the type of fetal monitoring used may not be assessing the correct indicators of mortality. In all other age groups, electrocardiographic (ECG) and continuous heart rate (HR) monitoring are us…
