Questions and Answers All
Correct
What is the most common of the transposition of the great arteries? - Answer- complete
The connection between the atria and ventricles is concordant - Answer- complete
transposition
How can you tell the difference between an overriding aorta and a double-right
ventricle? - Answer- 50% rule
If more than 50% of the aorta overrides the right ventricle, DORV is more likely -
Answer- 50% rule
_ & _ are used to denote the location of the aorta in relation to the pulmonary artery -
Answer- D & L
D= - Answer- right
L= - Answer- left
Both cases of the pulmonary artery arises from the ___ ventricle and aorta from the
____ ventricle - Answer- -left
-right
Aorta comes off the right ventricle and pulmonary comes off the left ventricle causing
deoxygenated blood to circulate systemically - Answer- complete transposition
Sonographic findings:
-Normal 4 chamber view
-Outflow tracts must be seen to diagnose
-When viewing the RVOT (short axis) pulmonary artery will not be seen encircling the
aorta. --Two vessels will appear side by side.
-Long axis they will be seen parallel to each other without the normal crossing pattern
-In the three vessel view, only two vessels will be seen the aorta and the superior vena
cava
-VSD or ASD must be present for oxygenated blood from the left ventricular (pulmonic)
circulation to reach the right ventricular (systemic) - Answer- complete transposition
, Congenitally correct transposition - Answer- l-transposition
Right atrium connects to left ventricle which is connected to the pulmonary trunk -
Answer- l-transposition

tricuspid valve is on the? - Answer- right
how many pulmonary arteries? - Answer- 2
how many pulmonary veins? - Answer- 4
the heart is ___ degrees to the left? - Answer- 45
how much of the thorax should the heart occupy? - Answer- 1/3
What ventricle should make the apex of the heart? - Answer- left
A common image taken at many facilities is a ______ image of the fetal abdomen and
heart showing fetal situs - Answer- dual
_____ are the most common malformation - Answer- CHD
HR less than 100 BPM - Answer- Bradycardia
HR greater than 180 BPM - Answer- Tachycardia
what is normal HR? - Answer- 120-160
what may lead to nonimmune hydrops? - Answer- arrhythmias
What are the two types of septal defects? - Answer- -ventricular
-atrial
what is the most common septal defect? - Answer- ventricular
