T/F: Pulmonary Atresia with Intact Ventrciular Septum has a better progniosis for the fetus than Pulmonary Atresia with a VSD.
FALSE (why???)
What is an AVSD made up of (which ASD and which VSD)
Septum Primm ASD with Inlet VSD
What does in mean when you see a double outlet ventricle, and which side is it more common on?
Outflow tracts originate from the same ventrcile usually on the RIGHT side
In Ebstein Anomaly, which chamber of the heart may appear most dilated?
Right Atrium
What is the difference between pulmonary stenosis and pulmonary atresia?
Atresia is the complete ABSENCE of the connection between the right ventricle and the aorta (yes the vessel may still be there but the connection is not). Stenosis is NARROWING of the vessel.
T/F: Right sided heart defects are more commonly associated with Turner Syndrome, while left sided heart defects are more commnly associated with maternal diabetes.
FALSE (turners for left and downs/diabetes for right)
How are the tricuspid and mitral valves placed in an AVSD?
Straight across (what is normal look like?)
What is Tricuspid Atresia?
Blood flow is not passing from the right atrium to the right ventricle
Stenosis of a Vessel often causes what sonographic artifact when using color flow?
Aliasing
What is the "Y-Sign" an indicator of in utero?
Overriding Aorta
What is the most common form of cyanotic heart disease?
TETS
When you find an AVSD with Tetraology of Fallot, what chromosomal abnormality should be suspected?
DOWNS
What in the 11-13 weeks early gestation scan may be an early indicator for fetal heart anomalies specifically at the level of the four chamber?
Tricuspid Regurgitation
What causes constriction of te Ductus Arteriosus during pregnancy (3 Things specifically)
Decrease of Prostaglandin during gestation (So also LATE gestation will begin to constrict), and NSAID/ Ibuprofen use
What are the four main components of Tetralogy of Fallot, and which one is NOT seen in utero?
What is the most common ASD?
ASD II Septum Secundum
When you find an AVSD with left side heart defects, what chromosomal abnormality should be suspected?
Turners
200 cm/sec or over
T/F Coarctation of the Aorta can cause Tricuspid Regurgitation
TRUE! Think of your circulation!
What structure is vitally important to check blood flow direction through in utero to determine whether the baby will be a Pink TET vs a Blue TET?
Ductus Arteriosus
Where does a Septum Secundum ASD occur?
Foramen Ovale (redundant flap etc)
A single ventricle that recieves blood from both atria is called ___, and it occurs more commonly on the ___ side of the heart.
Double Inlet Left Ventricle, Left Side
What is Atrialization of the Right Ventricle?
Ebstein Anomaly
In a fetus with severe pulmonary stenosis, what other valve may initially show regurgitation?
Tricuspid
What is the most COMMON congenital Heart defect?
Bicuspid Aortic Valve (Remember, VSD is only the most common SEEN IN UTERO, we don't usually find a BAv!)
