What you need to know right now: An echogenic intracardiac focus (EIF) is a bright spot seen on your baby's ultrasound. It is not a heart problem. It does not hurt your baby. In most cases, it requires no treatment or follow-up.
This presentation will help you understand what this finding means for you and your baby.
What Is an Echogenic Intracardiac Focus?
"Echogenic" means it reflects sound waves and appears bright white on ultrasound. "Intracardiac" means inside the heart. "Focus" means a small spot.
An EIF is a tiny bright spot that shows up on your baby's ultrasound, usually inside the left side of the heart.
What creates this bright spot?
It's a small area of calcium deposits on one of the heart's muscles or cords
Think of it like a small mineral deposit, similar to calcium in your bones
It's found in about 3-5% of all pregnancies
Important: An EIF is NOT a heart defect. Your baby's heart is forming normally and working properly.

What Does It Look Like on Ultrasound?
During your ultrasound, the sonographer looks at different views of your baby's heart to check that it's developing normally.
The EIF appears as:
A small, very bright white dot
Usually in the left ventricle (left pumping chamber)
Sometimes in the right ventricle
About the size of a grain of rice or smaller
The spot is so bright because calcium reflects ultrasound waves more than soft tissue does.
Where it's located: The EIF is typically on the papillary muscle or the cord-like structures that help the heart valves close properly. These structures are working normally even with an EIF present.

Why Does This Finding Matter?
Understanding the medical context
What doctors used to think:
In the 1990s and early 2000s, researchers noticed that EIF appeared slightly more often in pregnancies with certain chromosomal differences, particularly Down syndrome.
Because of this association, EIF was called a "soft marker" – a finding that might suggest further testing.
This information is now outdated. Medical knowledge has advanced significantly, and we now understand that an isolated EIF (by itself, without other findings) has very little clinical significance.
What We Know Now in 2026
Modern research shows:
An isolated EIF (no other ultrasound findings) does NOT meaningfully increase the chance of chromosomal differences
When genetic screening tests (like cell-free DNA testing) are normal, an EIF alone does not change your baby's risk
EIF is now considered a normal variant in fetal development
Current medical guidelines: The American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine (SMFM) state that isolated EIF should not be used as an indication for genetic testing or amniocentesis when other screening is normal.
This means your medical team will focus on the overall picture of your pregnancy, not just this one finding.
What Does This Mean for My Baby?
The most important facts:
Heart health: An EIF does NOT indicate heart disease. Your baby's heart is structurally normal and functioning properly. This is not a heart defect.
Genetic risk: If you've had normal genetic screening (like cell-free DNA or first-trimester screening), an isolated EIF does not change those results. Your risk remains the same as it was before the EIF was seen.
Research data:
Multiple large studies have shown that babies with isolated EIF have the same health outcomes as babies without EIF. The vast majority of babies with EIF are born healthy with no related complications.
Understanding "Isolated" EIF
"Isolated" means the EIF is the only unusual finding on your ultrasound.
When EIF is isolated:
All other parts of your baby's anatomy look normal
Your baby is growing appropriately
The placenta and amniotic fluid are normal
No other "soft markers" are seen
Multiple findings: If your ultrasound shows multiple soft markers or structural differences, your doctor may recommend genetic counseling. This is different from an isolated EIF and requires individualized discussion with your care team.
In most cases (over 90%), EIF is found in isolation and is truly a benign, incidental finding.
What Happens Next?
Testing and monitoring
Do you need additional testing?
If you've already had genetic screening:
Cell-free DNA (cfDNA) testing showed low risk → No additional testing needed
First-trimester screening was normal → No additional testing needed
Quad screen was normal → No additional testing needed
If you haven't had genetic screening:
Your doctor may offer routine genetic screening options
The EIF alone doesn't mean you must have invasive testing
Genetic counseling is available if you have questions
Amniocentesis: Current guidelines do NOT recommend amniocentesis based solely on an isolated EIF. The small risks of amniocentesis outweigh any benefit when EIF is the only finding.
Do You Need More Ultrasounds?
Short answer: In most cases, no additional ultrasounds are needed just because of an EIF.
What typically happens:
You'll continue with your routine prenatal care
You'll have your standard anatomy scan and any routine follow-up ultrasounds
The EIF doesn't require special monitoring or extra visits
What happens to the EIF?
Many EIFs fade or disappear by the third trimester
Some remain visible throughout pregnancy
Either way, it doesn't affect your baby's health
If your doctor recommends additional ultrasounds, it would be for other reasons related to your overall pregnancy, not because of the EIF alone.
What About After Birth?
Does your baby need heart testing after birth?
No. Babies with isolated EIF do not need echocardiograms or other heart tests after birth. The EIF is not associated with postnatal heart problems.
What happens to the calcium deposit?
It typically has no significance after birth
It doesn't affect heart function
It doesn't require any monitoring or treatment
Most children and adults have small areas of calcification in various tissues that cause no problems
Your baby will receive routine newborn care and the standard newborn heart screening that all babies receive.
What Can I Do?
The most important thing to know: There is nothing you did to cause an EIF, and there is nothing you can do to change it. It is not related to anything you ate, any activities you did, or any medications you took.
Your action plan:
Continue routine prenatal care – Keep all your regular appointments
Take your prenatal vitamins – This doesn't change EIF, but supports overall pregnancy health
Ask questions – Your care team is here to address your concerns
Focus on overall health – Healthy eating, staying active as able, and managing stress
Calcium intake: You should continue normal calcium intake as recommended during pregnancy. The EIF is not related to dietary calcium, and changing your calcium intake won't affect the EIF.
Managing Your Feelings
It's completely normal to feel worried when you learn about any finding on your ultrasound. Many parents describe feeling anxious even after understanding that EIF is benign.
Common emotions:
Worry about what this means
Confusion about conflicting information online
Frustration that something was "found"
Relief after learning more, but lingering concern
You're not alone: With 3-5% of pregnancies showing EIF, thousands of parents navigate these same feelings. The vast majority go on to have healthy babies.
Helpful strategies:
Talk with your partner, family, or friends about your concerns
Limit searching online – stick to reliable medical sources
Write down questions for your next appointment
Consider speaking with a genetic counselor if you need additional reassurance
Questions to Ask Your Doctor
Here are questions you might want to discuss at your next appointment:
About your specific situation:
"Was the EIF the only finding on my ultrasound?"
"Were all other parts of my baby's anatomy normal?"
"What were my genetic screening results?"
"Based on my overall risk assessment, do you recommend any additional testing?"
About next steps:
"What will happen at my next ultrasound?"
"Will you look at the EIF again, or is no follow-up needed?"
"Are there any specific things I should watch for or report?"
"Who can I contact if I have additional questions?"

Key Takeaways
The most important points to remember:
EIF is common – Found in 3-5% of all pregnancies
It's not a heart defect – Your baby's heart is forming normally
Isolated EIF is benign – When it's the only finding, it has no clinical significance
Normal screening stays normal – EIF doesn't change low-risk genetic screening results
No special treatment needed – Continue routine prenatal care
Healthy outcomes expected – The vast majority of babies with EIF are born healthy
You and your care team are partners in monitoring your pregnancy. An isolated EIF is one small piece of information in the larger picture of your baby's healthy development.
Moving Forward Together
Your healthcare team is here to support you throughout your pregnancy.
What we're monitoring:
Your baby's overall growth and development
