Fetal Echo Questions with Correct
Answers 2025/2026
Maternal indications for fetal echocardiogram - CORRECT ANSWER -family history of CHD
metabolic disorders (diabetes)
exposure to teratogens
autoimmune disease
familial inherited disorders
in vitro fertilization
Fetal indications for fetal echocardiogram - CORRECT ANSWER -abnormal OB ultrasound
screening
extracardiac anomalies
chromosomal anomalies
arrhythmias
hydrops
increased nuchal translucency
monochorionic twins
Optimal time to perform fetal echo - CORRECT ANSWER -18-22 weeks
fetal heart is developed by 8 weeks, but too small for imaging
usually around 22 weeks every patient has OB ultrasound as screening
> 22 weeks can be done but it's important to perform right away after an abnormal screening
Fetal echo protocol - CORRECT ANSWER -determine fetal position with long axis of mother's
abdomen, define fetal RT and LT
, obtain transverse view of upper fetal abdomen and determine visceral situs- liver and GB on RT
and stomach on LT. identify aorta and IVC (IVC more anterior than aorta)
moving superiorly image 4 chamber heart following IVC into RT atrium
Outflow tracts - CORRECT ANSWER -criss cross
RVOT= angle more anterior/superiorly
3 vessel view - CORRECT ANSWER -MPA, ascending aorta & SVC
P: pulmonary
A: aorta
C: cava
superior view of 4 chamber view
3 in straight line from LT anterior to RT posterior
descending in size, MPA largest, SVC smallest
ductus arteriosus: angle slightly superiorly
LT ventricular outflow tract view - CORRECT ANSWER -from 4 chamber slide transducer around
maternal abdomen so ventricular septum is horizontal: angle superiorly to open LVOT and aortic
valve
RT ventricular outflow tract view - CORRECT ANSWER -slide transducer ever so slightly superior
to demonstrate RV and RVOT
follow MPA bifurcating into RT and LT
LVOT - CORRECT ANSWER -more anterior, upward, and forward
connects with anterior leaflet of mitral valve
not as muscular
