Objectives: After studying the article entitled “Screening for Congenital Heart Disease: Sonographic Features and Techniques for Prenatal Detection,” you will be able to:
Describe the importance of cineloops and real-time imaging for assessment of the fetal heart
Determine optimal machine control settings for evaluation of the fetal heart for congenital disease
Describe the sonographic features of the fetal defects commonly associated with congenital heart disease
A large ventricular septal defect is an example of a ___________ type of congenital heart disease. Mild Severe: acyanotic Severe: cyanotic Critical
One of the most common forms of congenital heart disease is Truncus arteriosus Transposition of the great arteries Pulmonary stenosis Aortic stenosis
A standard four-chamber view showing a small left heart or an echogenic left ventricle is typically Tricuspid atresia Bicuspid aortic valve A feature of tetralogy of Fallot Hypoplastic left heart syndrome
Sensitivity of routine obstetric screening for congenital anomalies of the heart and great vessels is reported to be approximately 35% to 40% 50% to 55% 70% to 75% 85% to 90%
Hypoplastic right heart syndrome is an example of a ___________ type of congenital heart disease. Mild Severe: acyantoic Severe: cyanotic Critical
Normal fetal heart rate is approximately _________ beats per minute. 80 to 120 120 to 160 160 to 180 >180
Visualization of parallel outflow tracts is typically a sign of Tetralogy of Fallot Ebstein’s anomaly Transposition of the great arteries Coarctation of the aorta
A small, hypertrophied right ventricle with a small pulmonary artery is typically a sign of Hypoplastic right heart syndrome Aortic atresia Ebstein’s anomaly Ventricular septal defect
During the second trimester, the ventricular outflow tracts typically measure only 1 to 2 mm 2 to 6 mm 5 to 8 mm 8 to 10 mm
The low-risk population is reported to be the source of approximately _______ of congenital heart disease. 50% 60% 70% 80%
