Neonatal outcomes are generally good with normal fetal heart anatomy. However, functional cardiovascular abnormalities, particularly tricuspid regurgitation, are linked to higher neonatal bilirubin levels.
Area of Science:
- Perinatology
- Neonatal Medicine
- Pediatric Cardiology
Background:
- Neonatal hyperbilirubinemia is a common concern.
- Fetal cardiovascular abnormalities can impact neonatal health.
- Understanding the link between fetal heart function and neonatal outcomes is crucial.
Purpose of the Study:
- To analyze neonatal outcomes in fetuses with diagnosed functional cardiovascular abnormalities.
- To investigate the association between fetal cardiac functional anomalies and neonatal hyperbilirubinemia.
Main Methods:
- An observational study of 100 neonates was conducted.
- Fetal echocardiography was performed in the third trimester.
- Neonates were categorized into two groups: normal heart anatomy without functional anomalies and normal heart anatomy with functional abnormalities.
Main Results:
- In the group with functional abnormalities (28 cases), 46% exhibited elevated bilirubin levels (>10 mg/dL).
- Tricuspid regurgitation was observed in 53% of cases within the abnormal group.
- A statistically significant difference in elevated bilirubin levels was found between groups (p < 0.001).
Conclusions:
- Normal fetal heart anatomy generally predicts a good neonatal outcome.
- Functional cardiovascular abnormalities, especially tricuspid regurgitation, are associated with an increased risk of neonatal hyperbilirubinemia.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
