A fetal echocardiogram is a specialized ultrasound test that evaluates the heart of a fetus during pregnancy. It is typically performed between 18 and 24 weeks of gestation when the heart is fully developed. This test provides detailed images of the fetal heart, including its chambers, valves, and blood flow, helping to identify congenital heart defects or other abnormalities. The procedure is safe for both the mother and the baby, using high-frequency sound waves to create images of the fetal heart. A trained sonographer conducts the test, and a pediatric cardiologist interprets the results. Based on the findings, further monitoring, testing, or interventions may be recommended during pregnancy or after birth.
