✍️ Sample FE Questions & Answers
1. A z-score of −2.0 for the aortic valve annulus diameter means the measurement is:
A z-score of −2.0 means the aortic annulus is 2 standard deviations below the expected mean for that gestational age or fetal weight, indicating significant hypoplasia.
2. Which view best demonstrates the relationship of the pulmonary veins to the left atrium in fetal echocardiography?
Angling the transducer posteriorly from the four-chamber view allows visualization of pulmonary vein insertion into the posterior left atrium.
3. Which embryonic structure is the origin of the sinus node and contributes to the superior vena cava?
The sinus venosus, the most caudal part of the primitive heart tube, gives rise to the sinus node, the coronary sinus, and incorporates into the posterior right atrium.
4. Which echocardiographic finding is most characteristic of hypoplastic left heart syndrome (HLHS)?
HLHS is characterized by a severely underdeveloped left ventricle associated with aortic and/or mitral atresia or severe stenosis.
5. Which M-mode measurement is used to calculate the cardiothoracic ratio in fetal echocardiography?
The cardiothoracic ratio is obtained by dividing the maximal cardiac diameter by the thoracic diameter measured in the same transverse plane.
6. Which imaging plane provides the best view of the four chambers of the fetal heart?
The four-chamber view is the standard plane used to evaluate the size and symmetry of the atria and ventricles.
