Yes, fetal echocardiography is safe. It uses high-frequency sound waves, not ionizing radiation, to produce images. There are no known risks associated with the procedure.

While fetal echo can detect many structural heart defects, it may not identify every possible condition. Some minor or subtle abnormalities might only become apparent after birth.

The ideal time for a fetal echo is between 18 to 24 weeks of pregnancy. At this stage, the fetal heart is developed enough for a detailed evaluation.

If a heart defect is detected, the healthcare team will discuss the findings with the parents and provide information about potential treatment options, including surgical interventions after birth. The care team may also coordinate delivery at a specialized center for advanced neonatal care.
