Isolated Echogenic Intracardiac Focus (EIF)

A small bright spot seen in the baby's heart

An echogenic intracardiac focus, or EIF, is a tiny bright spot seen inside the baby's heart during an ultrasound. It looks as bright as bone on the screen.  Isolated means it is the only finding.

An EIF is common and does not harm the baby. By itself, it is not a heart defect.

An EIF is not a birth defect

What causes the bright spot?

The bright spot may be caused by a tiny amount of calcium in a heart muscle or tendon. It does not cause long-term problems for the baby.

How common is it?

EIF is seen in many healthy babies. It appears to  be more common in some families and ethnic groups.

Does EIF mean Down syndrome?

Most babies with an EIF do not have Down syndrome. Your care team will look at your earlier screening results and the rest of the ultrasound.

What happens next?

  • For pregnant people who have a negative serum or cfDNA screening and only an echogenic spot in the baby's heart, the Society for Maternal Fetal Medicine recommends no more testing. This spot is a normal finding and does not mean there is a heart problem, so no special heart ultrasound, follow‑up imaging, or checks after birth are needed.
  • If you have not had screening, cell-free DNA or a quad screen may be offered.
  • If there are other ultrasound findings, more testing or genetic counseling may be discussed.
Important:"Isolated EIF" means  the EIF is the only ultrasound finding after a detailed exam. Your doctor or ultrasound specialist will explain whether this applies to your pregnancy.
What should I remember? An isolated EIF with low-risk screening is considered a normal finding and usually does not need treatment before or after birth.

Please ask your obstetrician or maternal-fetal medicine specialist about your ultrasound and screening results. Each pregnancy is different.
