Summary
Early detection of fetal Ebstein
Area of Science:
- Prenatal diagnosis
- Fetal cardiology
- Congenital heart disease
Background:
- Ebstein's anomaly is a rare congenital heart condition affecting the tricuspid valve.
- Its prenatal diagnosis can be challenging, especially in early gestation.
Purpose of the Study:
- To describe sonographic findings of fetal Ebstein's anomaly.
- To evaluate its appearance in early and late pregnancy.
Main Methods:
- Fetal sonography was conducted in 53,447 pregnancies between 14-16 weeks' gestation.
- Sonographic findings were analyzed for Ebstein's anomaly detection.
Main Results:
- Eight fetuses (0.015%) were diagnosed with Ebstein's anomaly; four had additional anomalies.
- One fetus initially appeared normal at 15 and 24 weeks but was diagnosed postnatally with Ebstein's anomaly and pulmonary stenosis.
Conclusions:
- Fetal Ebstein's anomaly can be detected via sonography in early pregnancy.
- The incidence may be higher than previously reported.
- A normal early fetal echocardiogram does not rule out later development of Ebstein's anomaly.

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
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...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
