Objectives: After studying the article entitled “Sono-graphic Evaluation of Fetal Cardiac Anatomy in the Late First Trimester,” you will be able to:
Identify recommended protocols for late first-trimester cardiac evaluation
Discuss indirect markers for congenital heart defect (CHD)
Describe three-dimensional (3D) rendering of the fetal heart
What percentage of risk is present if the mother of the baby has a congenital cardiac anomaly? 2% 12% 50% 4%
What is the first step for first-trimester fetal heart evaluation? Evaluate the four-chamber view (4CV) Identify three-vessel tracheal view (3VTV) Evaluate outflows tracts Determine cardiac position and axis
In Figure 6, the white arrow is pointing to which anatomic structure? Ductus arteriosus Pulmonary artery Aorta Pulmonary vein
Which of the following is an indirect marker for CHDs in the first trimester? Tricuspid regurgitation Mitral regurgitation Biphasic ductus venosus Absent flow in ductus arteriosus
A fetal echocardiogram is the current gold standard for identification of CHD in which of the following stage? Late first trimester Early first trimester Second trimester Third trimester
What is the ideal time to incorporate early cardiac screening? 11 to 12 weeks’ gestation 11 to 13 weeks 6 days’ gestation 10 to 14 weeks’ gestation 11 to 13 weeks 5 days’ gestation
According to Wiechec et al., which of the following technique was more effective than the other over the 4CV and 3VTV? Color mapping Pulse Doppler M-mode Power Doppler
What are the recommended techniques for evaluating the fetal heart for anomalies between 11 weeks and 13 weeks 6 days? Gray-scale imaging and 3D Color Doppler and 3D Gray-scale imaging and 4D Power Doppler and 3D
What is the range for the fetal cardiac axis at 12 weeks’ gestation? 15° to 60° 30° to 50° 10° to 65° 25° to 65°
Which of the following ratios is suggestive of cardiomegaly? <0.28 0.28 >0.28 0.25
