During the examination of Nuchal Translucency (11-14 weeks), Anomaly scan (20-24 weeks) and Growth Scan (28-36 weeks), we systematically examine the fetal heart and the connections of the large vessels.

However, if there are any particular findings, a specialized and more detailed ultrasound examination by a pediatrician - cardiologist is recommended.

These cases are mainly:

• Women with an individual or family history of congenital heart disorders (or partner's history).

• Cardiac abnormalities in a previous pregnancy or child .

• Patients with predominantly insulin-dependent diabetes mellitus.

• History of Systemic Lupus Erythematosus (SLE) with anti-Ro or anti-La antibodies.

• Increased Nuchal Translucency ≥ 3.5mm.

• In monohorionic multiple pregnancies.

• Ductus venosus agenesis.

• Reversed blood flow in the ductus venosus during the nuchal scan.

• Tricuspid valve regurgitation during the first or/and the second trimester of the pregnancy.

• Women who are on specific medication (e.g. anti-epileptics).

• Suspicion of complex to identify heart abnormalities.
