What is best cardiac view for visualizing Persistent truncus arteriosus
Apical 5ch and long axis of aorta
Best sonographic view for diagnosing an AVSD
Apical 4 ch and subcostal 4 ch
Which view best demonstrates the atrioventricular junction including the valve leaflets and annulus
Apical 4ch
Short axis view
Subcostal 4 ch view
In the apical 4ch heart view how is the interventricular septum orientated in relation to the sound beam
Parallel
Standard views of heart for fetal echo
Apical 4 ch
Short axis of GA
Long axis of AO
Long axis view of the PA
What is the most posterior chamber and closet to fetal spine
Left atrium
Long axis of the aorta looks like what view
Lvot
In the long axis of the left heart what structures are visible
Left atrium , mitral valve, papillary muscle , right ventricle and left ventricle
In the long axis of the pulmonary artery the normal pulmonary artery courses
Cephalad leftward and posterior to the right ventricle
The great arteries cross with the pulmonary artery and the aorta at what angle
135 degree angle
The position of the pulmonic valve in relation to the aortic valve is
Anterior and superior
When scanning through the fetal heart at what level do you determine the normal great artery position
Where the aorta and pulmonary artery cross
And the at the level of the semi lunar valves
In the short axis view of the great vessels all the following can be demonstrated
Foramen ovale
Pulmonic valve
Left atrium
Tricuspid valve
Best view to eval aortic cusps
Short axis of great vessels
In 3VV which vessel is most anterior
Pulmonary
True statements of the ductus arteriosus
The ductus arteriosus has a hockey stick appearance and has a higher peak systolic velocity when compared to the aorta
What modality is used to display movements as they occur in tissue on a time axis
M mode
M mode displays depth on vertical axis vs time on horizontal axis
M mode is mainly used to demonstrate movement of cardiac structures
Which sonographic modality displays a single B mode line of site along a horizontal axis
M mode
M mode stands for motion mode
In CC : TC what ratio is diagnostic of cardiomegaly
> 0.5
Pulmonic valve measures 0.63cm in 3VV is this normal or abnormal
Normal
The normal range is 5.0-7.0 mm
When evaluating for an ASD the examiner must know that the atrial to ventricular ratio in a normal fetus should be
1:2
The atria should be half the size of the ventricles when measure ant to post wall
What is considered a normal appearance and normal amount of fluid around the fetal heart
Hypoechoic rim of fluid less than 2 mm
The 4ch heart view has been reported to have a sensitivity of what percentage in detecting a CHD
40-57%
