Fetal Findings on Routine Scans:

• Abnormal four-chamber view or outflow tracts
• Abnormal heart rate or rhythm
• Other structural anomalies that may be associated with heart defects
• Increased nuchal translucency in the first-trimester screening

What to Expect During the Scan

The scan is non-invasive and safe for both mother and baby. It usually takes 30 to 60 minutes. If an abnormality is found, further genetic testing, monitoring, or coordination with a pediatric cardiologist and neonatal care team may be recommended.

Fetal echocardiography is a vital tool for early detection and management of congenital heart conditions. While not every pregnancy requires this test, it offers crucial information when risk factors are present. If your healthcare provider recommends fetal echo, know that it’s a step toward ensuring the best possible outcome for your baby.
