Which sonographic view is optimal for visualizing the atrial and ventricular septa in fetal echocardiography?
Outflow tract view
Short-axis view
Four-chamber view
Subcostal view
The four-chamber view clearly shows both atria and ventricles and their septa. It is the primary screening view for septal integrity in the fetal heart.
In the left ventricular outflow tract (LVOT) view, which structure is visualized leaving the left ventricle?
Pulmonary artery
Mitral valve
Aorta
Tricuspid valve
The LVOT view displays the aorta as it arises from the left ventricle. Identifying the aorta in this view helps assess position and caliber.
During what gestational age range is fetal echocardiography typically performed for optimal heart evaluation?
18 - 22 weeks
12 - 14 weeks
28 - 32 weeks
6 - 8 weeks
Fetal echocardiography is optimally performed between 18 and 22 weeks when cardiac structures are well developed. Earlier or later exams are less informative for certain anomalies.
What is the normal resting fetal heart rate range on ultrasound?
80 - 100 bpm
100 - 120 bpm
160 - 180 bpm
120 - 160 bpm
A normal fetal heart rate ranges from 120 to 160 beats per minute. Rates outside this range may suggest arrhythmia or distress.
Which Doppler mode is primarily used to measure the velocity of blood flow in fetal cardiac vessels?
3D Doppler
Color Doppler
Pulsed wave Doppler
M-mode
Pulsed wave Doppler places a sample volume in a vessel to measure peak and mean flow velocities. It is standard for quantitative assessment of fetal cardiac flow.
Which measurement assesses fetal cardiac size relative to thoracic dimensions?
Cardiothoracic ratio
Nuchal fold thickness
Femur length
Crown-rump length
The cardiothoracic ratio compares the cardiac area to the thoracic area on an axial view. A ratio below 0.5 is considered normal.
What is the normal upper limit for the fetal cardiothoracic ratio?
0.25
0.75
1.0
0.5
A normal fetal cardiothoracic ratio is less than or equal to 0.5. Ratios above this value suggest cardiomegaly.
When using pulsed Doppler to assess mitral inflow, where is the sample volume placed?
Inside the left atrium
In the left ventricular outflow tract
At the interventricular septum
At the tip of the mitral valve leaflets
The sample volume is placed at the tips of the mitral leaflets to capture early (E) and late (A) diastolic filling velocities. This helps evaluate ventricular diastolic function.
Which prenatal ultrasound finding is characteristic of pulmonary atresia?
Enlarged left ventricle
Thickened atrial septum
Absence of right ventricular outflow tract flow
Pericardial effusion
Pulmonary atresia is defined by absence of flow through the pulmonary valve and right ventricular outflow. It results in underdeveloped pulmonary arteries.
An increased peak systolic velocity in the middle cerebral artery on Doppler suggests which fetal condition?
Anemia
Polycythemia
Hypothyroidism
Hydrocephalus
Elevated MCA peak systolic velocity indicates reduced blood viscosity from anemia. This is a noninvasive marker for fetal anemia.
Which anomaly presents with 'parallel' great vessels on the outflow tract views?
Transposition of the great arteries
Truncus arteriosus
Tetralogy of Fallot
Coarctation of the aorta
In transposition of the great arteries, aorta and pulmonary artery run parallel instead of crossing. This abnormal relationship is diagnostic.
Which M-mode parameter assesses fetal ventricular systolic function?
Tricuspid regurgitation velocity
Fractional shortening
Peak E velocity
A-wave reversal
Fractional shortening measures the percentage change in ventricular diameter between diastole and systole. It reflects contractile performance.
On color Doppler, a ventricular septal defect is identified by which feature?
Absent color signal
High-velocity flow in the aorta
Jet crossing the ventricular septum
Flow along the atrial septum
A VSD appears as a colored jet traversing the septum due to pressure difference. The location and size help determine hemodynamic significance.
Maternal diabetes is most strongly associated with which fetal cardiac abnormality?
Ebstein anomaly
Truncus arteriosus
Hypoplastic left heart syndrome
Hypertrophic cardiomyopathy
Poorly controlled maternal diabetes can cause fetal myocardial hypertrophy. This leads to septal and ventricular wall thickening.
Which transverse view shows the right ventricular outflow tract, aortic arch, and superior vena cava?
Three-vessel view
Apical four-chamber view
Subxiphoid view
Short-axis view
The three-vessel view displays pulmonary artery, aorta, and superior vena cava in cross-section. It assesses relative size and alignment.
Which ultrasound feature is diagnostic for Ebstein anomaly in the fetus?
Absent pulmonary valve
Apical displacement of tricuspid valve leaflets
Overriding aorta
Hypoplastic right ventricle
Ebstein anomaly is defined by apical displacement of the septal and posterior tricuspid leaflets into the right ventricle. This causes atrialization of part of the ventricle.
A reversed A-wave in the ductus venosus Doppler trace indicates which fetal condition?
Normal cardiac compliance
Increased cardiac preload and dysfunction
Mild pulmonary stenosis
Atrial septal defect
Reversal of the A-wave reflects elevated right atrial pressure and impaired ventricular compliance. It is a marker of significant cardiac dysfunction.
In fetal echocardiography, z-scores are used to normalize cardiac measurements to what parameter?
Fetal heart rate
Placental thickness
Gestational age and fetal size
Maternal age
Z-scores standardize measurements for gestational age and overall fetal size. They allow comparison to normative data and detection of abnormal growth.
Maternal autoimmune conditions like lupus predispose the fetus to which cardiac finding?
Transposition of the great arteries
Tetralogy of Fallot
Persistent truncus arteriosus
Congenital heart block
Maternal anti-Ro and anti-La antibodies can cross the placenta and damage the fetal conduction system, leading to congenital heart block.
Which 3D ultrasound technique allows dynamic volumetric assessment of the fetal heart?
B-flow imaging
Power Doppler
Spatio-Temporal Image Correlation (STIC)
Contrast-enhanced 3D
STIC acquires a volume dataset over time, enabling cine display of the beating fetal heart. It is valuable for complex structural analysis.
