NCT ID: NCT03775954 Recruiting - Clinical trials for Congenital Heart Disease

Fetal Electrophysiologic Abnormalities in High-Risk Pregnancies Associated With Fetal Demise

Start date: July 1, 2018
Phase:
Study type: Observational

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.

NCT ID: NCT03214328 Recruiting - Clinical trials for Intrauterine Fetal Death

Causes of Fetal Death: Comparison of Diagnostic Accuracy Between Extensive and Selective Protocol Testing

EMIBICI
Start date: November 21, 2019
Phase:
Study type: Observational

Intrauterine fetal death (IUFD) is defined as the occurrence of fetal death at >20 weeks' gestation. IUFD affects about 1 in 160 pregnancies (6-7 per 1000 births). Optimal diagnostic evaluation for cases of IUFD is generally based on extensive protocol testing i.e. maternal and fetal blood tests, fetal bacteriology, cytogenetic analysis, autopsy, and placental examination. This extensive protocol testing may vary in clinical practice and interpretation of the results is rarely performed by multidisciplinary staff to establish cause of death. These findings are related to the fact that there are very few epidemiological studies to validate optimal protocol, no French recommendations on this subject, and a relative lack of pathologists with expertise in perinatal pathology. Only, one recent prospective study from the Netherlands has concluded that extensive protocol testing should be redefined and some diagnostics tests may only be performed with suggestive clinical circumstances. However these recommendations may not be applicable to all populations and countries. To date, there are no French published series on IUFD to evaluate causes of death in France and thereafter to better define optimal diagnostic evaluation tests. Improvement in prenatal diagnosis in France may contribute to detection of the vast majority of severe chromosomal abnormalities and malformed fetuses and particularly those at risk of death. Retrospective cohort unpublished data on IUFD from Lille and Caen have reported exceptional deaths attributable to chromosomal or malformation abnormalities. In fact in these two series, most deaths were related to placental diseases or fetal growth retardation. The hypothesis is that extensive protocol testing is not helpful in clinical practice and selective protocol testing focused on specific risk situations can be as efficient.

NCT ID: NCT00856076 Recruiting - Clinical trials for Venous Thromboembolism

Venous Thromboembolism in Pregnancy Study

VIP
Start date: January 2005
Phase: N/A
Study type: Observational

The purpose of this study is to investigate clinical, biochemical and genetic risk factors for venous thromboembolism in pregnancy and pregnancy related vascular complications, and the long-term outcome of such complications including implications for quality of life.

NCT ID: NCT00573118 Active, not recruiting - Preeclampsia Clinical Trials

Severe Pregnancy Complications Are Associated With Elevated Factor VIII Plasma Activity

Start date: January 2000
Phase: N/A
Study type: Observational

Congenital and acquired thrombophilia were identified as risk factors for thrombosis in systemic vessels.Thrombophilias have also been recently found to be associated with preeclampsia, intrauterine fetal growth restriction (IUGR), placental abruption, intrauterine fetal death (IUFD) and repeated pregnancy loss.These severe pregnancy complications are thought to result from thrombotic events occurring in the uteroplacental circulation. Accumulating data have established an association between elevated plasma activity of factor VIII and thrombosis although the mechanism is still not defined and elevated factor VIII activity is now regarded as being equivalent to thrombophilia. We intend to investigatthe association between factor VIII levels and severe pregnancy complications which are considered to result from placental vascular pathology, i.e., preeclampsia, IUGR, placental abruption and IUFD. We hypothezise that the prevalence of elevated factor 8 will be higher among women with pregnancy complications compared to controls.
