Q

Is there an increase or decrease in pulmonary vascularity in Tetralogy of Fallot?

A

Decrease – decreased size of vessels (therefore, smaller hilum)

16
Q

What is the radiological shape of the heart in an Ebstein’s anomaly?

A

Box-shaped

17
Q

What is the M/C location where a TOTAL anomalous pulmonary venous return drains into?
What are some other locations?

A

M/C left brachiocephalic vein (innominate vein).

Other:

  • coronary sinus
  • right atrium
  • R/L superior vena cava
  • portal vein
18
Q

What is the M/C cardiac anomaly? What is the 2nd?

A 
1st = Atrial septal defect
2nd = ventral septal defect
19
Q

What is the M/C location for a PARTIAL anomalous pulmonary venous return?

A

Right atrium

20
Q

What is the scimitar syndrome?

A

Hypoplasia of right lung + anomalous right pulmonary venous return into the IVC

21
Q

What is Taussig-Bing?

A

Transposition of aorta arising from right ventricle + pulmonary artery overrides ventricular septum + ventricular septal defect

22
Q

What is the Eisenmenger complex?

A

A left-to-right shunt over time becomes a right-to-left shunt d/t left ventricular failure.

23
Q

What is the main cause for why a left-to-right shunt converts into a right-to-left shunt?

A

Pulmonary hypertension

24
Q

Are the pulmonary vessels increased, decreased or normal in patent ductus arteriosus?

A

Increased

25
Q

In which direction is the shunt in a patent ductus arteriosus?

A

Left-to-right

26
Q

In which direction is the shunt in a atrial septal defect?

A

Left-to-right

27
Q

What 4 left-to-right shunts cause an increase in the pulmonary artery?

A

1) Atrial septal defect
2) Ventricular septal defect
3) Patent ductus arteriosus
4) Lutembacher’s syndrome

28
Q

Which condition consists of atrial septal defect + congenital or acquired mitral stenosis + increased pulmonary artery?

A

Lutembacher’s syndrome

29
Q

What is a atrioventricularis communis?

A

Low atrial septal defect + high ventricular septal defect + cleft in mitral & tricuspid valves

30
Q

What is the M/C associated abnormality with coarctation of the aorta?

A

Bicuspid aortic valve (85%)

31
Q

Rib notching seen with aortic coarctation is M/C seen at which levels and what side?

A

4-8th inferior ribs; bilateral but asymmetric

32
Q

Where the M/C site of constriction in aortic coarctation?

A

At or distal to ductus arteriosus.

33
Q

What sign is on the esophagus on a barium swallow when aortic coarctation is present?

A

Reverse 3 sign (aka E sign)

  • as opposed to the figure-3 sign seen on the plain film involving the aorta.
34
Q

What is endocardial cushion defect?

A

Large hole in center of heart where wall/septum joins upper and lower chambers of the heart. Tricuspid and mitral valves may be one large valve.

35
Q

What is the M/C/C of mitral stenosis?

A

Rheumatic fever

36
Q

What is the M/C/C for aortic stenosis?

A

Rheumatic heart disease

37
Q

What is the snowman sign?

A

Seen in total anomalous pulmonary venous return - the supracardiac (SVC) variant.
