About The Test
Quick snapshot: what the scan checks
- Size, shape, and structure of the fetal heart
- Valve motion and blood-flow patterns
- Heart rhythm and rate for arrhythmias
Why Cadabams Diagnostics is trusted for fetal echo
- Accredited sonographers specialized in fetal cardiology
- 3-D/4-D and Doppler technology for razor-sharp images
- Same-day preliminary report to reduce waiting stress
What is Pregnancy Fetal Echo Ultrasound Scan?
Definition & technology used
A Pregnancy Fetal Echo Ultrasound Scan uses high-frequency sound waves—no radiation—to create real-time pictures of your baby’s heart. The scan is performed trans-abdominally, just like a routine ultrasound.
Difference between regular ultrasound and fetal echo
Regular Ultrasound | Fetal Echo |
---|---|
General anatomy check | Detailed cardiac focus |
15–20 minutes | 20–45 minutes |
Basic 2-D images | 2-D, 3-D/4-D, and Doppler |
Types of Pregnancy Fetal Echo Ultrasound Scan
- 2-D fetal echo – Standard grayscale imaging
- 3-D/4-D fetal echo – Adds depth and live motion
- Doppler fetal echocardiography – Measures blood-flow velocity and direction
List of Parameters
- Heart chambers: size & symmetry
- Valves: structure & function
- Blood-flow patterns: direction & velocity
- Heart rhythm & rate: early arrhythmia detection
Why This Test
- Screen for congenital heart defects
- Monitor known cardiac anomalies
- Reassurance for at-risk pregnancies
When to Take Test
- Ideal gestational age: 18–24 weeks
- High-risk mothers:
- Pre-existing diabetes
- Family history of congenital heart disease (CHD)
- Abnormal routine scan findings that flag possible cardiac issues
Benefits
Benefits of Taking the Scan
- Early detection enables treatment planning before birth
- Reduces anxiety with clear, real-time images
- Guides delivery & neonatal care decisions, including hospital selection and pediatric cardiologist involvement
Illnesses Diagnosed with Pregnancy Fetal Echo Ultrasound Scan
- Septal defects – ASD, VSD
- Valve stenosis or atresia
- Tetralogy of Fallot
- Arrhythmias – bradycardia, tachycardia, ectopic beats
Preparing for test
- Wear loose two-piece clothing for easy abdominal access
- Moderately full bladder improves image quality
- Bring previous scan reports for comparison
Pre-requisites
- Doctor’s prescription (mandatory)
- Valid ID & medical records
- Fasting not required – eat normally
Best Time to Take the Scan
- Optimal window: 18–24 weeks gestation
- Earlier or later scans ordered if clinically indicated
Eligibility
- Pregnant women at 18+ weeks
- High-risk cases referred by OB/GYN
- No upper gestational cut-off for emergency scan
Procedure for Taking a Pregnancy Fetal Echo Ultrasound Scan
- Step 1: Check-in & ID verification
- Step 2: Lie back; gel applied to abdomen
- Step 3: 20–45 min of detailed imaging
- Step 4: Immediate preliminary feedback from sonographer
Caution Before Taking the Test
- Inform sonographer of allergies to ultrasound gel
- Mention twin or multiple pregnancies for adjusted protocol
- Avoid caffeine 2 hrs prior to keep baby calm for clearer images
Test Results
Results and Interpretations
Finding / Observation | Description | General Interpretation / Significance |
---|---|---|
Normal 4-chamber view | Balanced heart size | Low risk for major CH |
Small VSD | Hole between ventricles | Often closes before birth; follow-up needed |
Valve stenosis | Narrowed valve opening | May need post-delivery intervention |
Irregular rhythm | Skipped beats | Usually benign; further monitoring advised |
Risks & Limitations
No radiation, minimal risk
Ultrasound is non-invasive and harmless for both mother and baby.
Limitations:
- Maternal obesity may reduce image clarity
- Fetal position can obscure certain views
- Follow-up scans sometimes needed for optimal assessment
FAQs
How long does the scan take?
20–45 minutes.
Is fetal echo safe for my baby?
Yes, ultrasound uses harmless sound waves.
When will I get results?
Same-day preliminary report; full report within 24 hrs.
What if a defect is found?
Referral to pediatric cardiologist for management plan.
Do I need a full bladder?
Moderately full bladder improves image quality.
Can I eat before the scan?
Yes, no fasting required.
