Q

With pulmonary stenosis, what is narrowed?

A

Pulmonary valve

17
Q

What is transposition of the great vessels?

A

When the PA arises from the LV and the aorta arises from the RV

18
Q

Tuberous sclerosis:

A

a systemic disorder that leads to the development of tumors within various organs

19
Q

The heart begins as two tubes

A

true

20
Q

What CRL measurement should you see fetal heart activity?

A

4-5mm

21
Q

Heart is fully formed by

A

10wks

22
Q

Umbilical vein carries what type of blood?

A

Oxygenated

23
Q

How much blood is shunted into the ductus venosus?

A

50%

24
Q

What’s the leading cause of cardiac death in the neonatal period?

A

Hypoplastic left heart syndrome

25
Q

When you see hypoplastic left heart syndrome in girls, what should you suspect?

A

Turner’s syndrome

could also think Tri18

26
Q

Hypoplastic right heart syndrome results from

A

pulmonary stenosis or atresia, but could also be from absent tricuspid valve

27
Q

Most common form of cardiac defect?

A

VSD

28
Q

AVSD’s are commonly associated with:

A

aneuploidy, tri21 and tri18

29
Q

What is the Ebstein anomaly associated with?

A

tricuspid regurgitation, ASD’s, ToF, trans of GV and coarctation of the aorta

30
Q

Can infants survive with Ebstein’s anomaly?

A

Prognosis is poor, 80% of fetuses pass in the perinatal period

31
Q

What is the most common location of coarctation of the aorta?

A

left SVA and ductus arteriosus

32
Q

Echogenic foci are most often seen

A

LV – which could represent the papillary muscle or chordae tendinae

33
Q

Rhabdomyomas have an association with?

A

tuberous sclerosis, cardiac failure and fetal hydrops

34
Q

Is prognosis good or bad with ecoptia cordis

A

Bad

Most common location of a diaphragmatic hernia?

A

Left

38
Q

What is the most likely reason of cardiac malpositon?

A

Diaphragmatic hernia
