Q

How can we find residual leaks with septal patches?

A

Use low color doppler to asses for flow at the edges of the patch or around the sutures

Q

Why may thrombus form with a septal patch?2

A
  1. May form on the surface of the patch in early stages, before the patch “endotheliazes”
  2. Once the endocardium grows over the patch, it is incorporated into the wall (6 weeks)

Q

What is another name for Arterial switch?

A

Jatene procedure

20
Q

What does Arterial switch involve?

A

Switching the aorta and PA to their normal positions

21
Q

When performing arterial switch, and moving the coronary arteries to a new aorta, what must we do first?

A

Check for RWMA from coronary abnormalities

22
Q

When is arterial switch performed?

A

Within the first weeks of life

23
Q

What is something that is noticeable after arterial switch?

A

The PA is now anterior to the AO

24
Q

What do we evaluate for if we have a patient that has undergone arterial switch?4

A
  1. Scarring at the suture lines on Aorta or PA
  2. Wall motion abnormalities
  3. Valvular regurgitation/ stenosis
  4. Residual shunts
25
Q

What is atrial switch also known as?

A

Senning/ mustard method

26
Q

What is the atrial switch?

A

Switches the atria using baffles (conduits) to line up the appropriate ventricle

27
Q

What is the process of flow for the Atrial switch?

A
  1. SVC/IVC flow is redirected through the baffle to the MV/LV which now becomes the pulmonary ventricle
  2. PVs flow redirected behind the other baffle to bring LA flow to the RV which now becomes the systemic ventricle
28
Q

Which is the more common D-TGA switch method?

A

Arterial switch

29
Q

With Atrial switch O2 rich pulmonary venous return is directed where?

A

TV

30
Q

With atrial switch O2 Poor SVR blood is directed where?

A

MV

31
Q

What does the Morphologic LV do with atrial switch?

A

Lungs

32
Q

What does the morphologic RV do with Atrial switch?

A

Pumps aorta

33
Q

What is the post procedure flow similar to in terms of atrial switch?

A

ccTGA

34
Q

What are some complications of senning/mustard method?5

A
  1. Baffle leaks + obstructions
  2. RV systolic dysfunctions
  3. PS
  4. Valvular regurgitation
  5. Arrythmias
35
Q

Do baffles grow in with patients?

A

no

38
Q

What does this image represent?

A

39
Q

What does this image represent?

A

Blalock taussig shunt

40
Q

What does this image represent? What does the numbers represent?

A

Surgical repair of Tetralogy of flow

  1. Open PV
  2. Close VSD
  3. Transannular RVOT
  4. +/- Rastelli procedure (pulmonary atresia)
41
Q

What does this image represent?

Q

What does this image represent?

A

45
Q

What does this image represent?

A

Coarctation of the aorta (CoA)

46
Q

What does this image represent?

A

Mitral commissurotomy

47
Q

What does these images represent?

A

Left: old school method for Mitral commissurotmy

Right: New school balloon (Percutaneous method)
