Objectives: After studying the article entitled “Assessment of the Fetal Heart During Routine Obstetrical Screening: A Standardized Method,” you will be able to:
Perform a basic fetal cardiac assessment
Define the elements comprising the basic assessment
Describe the typical sonographic findings of a basic assessment
The use of cine loop sweeps in the basic fetal heart assessment has been reported to increase the detection of congenital heart defects by experts and nonexperts alike by 25%–30% 30%–35% 35%–40% 40%–45%
The basic assessment of the fetal heart during an obstetrical screen requires the Four-chamber view Parasternal long-axis view Left ventricular outflow tract Right ventricular outflow tract
Machine settings for adequate image acquisition of the fetal heart should include a frame rate of at least 20 frames per second 25 frames per second 30 frames per second 35 frames per second
Congenital heart disease is reported to have an incidence in all live births of 0.6% 0.8% 1.2% 1.8%
Using the basic assessment with extended views in unselected patients, the prenatal detection rate for congenital heart disease in the largest series reported was 65% 36% 39% 57%
The complete inverse of the normal fetal heart anatomy is Situs solitus Situs inversus Right atrial isomerism Left atrial isomerism
The fetal heart in the right chest with a rightward apex is Dextroversion Dextroposition Mirror image dextrocardia Right transposition
In normal fetal heart anatomy, the left and right ventricular outflow tracts should cross at approximately 50 degrees 60 degrees 70 degrees 80 degrees
In most normal studies, at least ______ of the pulmonary veins will be seen Two Three Four None
Congenital heart disease is reported to be more common than neural tube defects by a factor of 0.8 4 6 8
