Lecture 2 / Tetralogy of Fallot / Pic on page 114

Question 1

Tetrology of Fallot (TOF)

Answer 1

• VSD
• Pulmonary Artery Stenosis
• Overriding Aorta
• RV Hypertrophy / RVOTO

Question 2

Pentalogy of Fallot

Answer 2

• VSD
• ASD
• Pulmonary Artery Stenosis
• Overriding Aorta
• RV Hypertrophy

Question 3

What kind of circulatory problems does Tetralogy of Fallot cause?

Answer 3

As the severity of RVOTO increases, 
- RIGHT to LEFT shunting of 
  blood occurs through he VSD.
- Cyanosis Occurs 
- Known as "Blue Tet"

Question 4

Hypercyanosis episodes due to the right to left shunting of blood in TOF are also know as what ?

Answer 4

“Tet Spells”

Question 5

What kind of problem do “Blue Tets” have ?

How can we fix it?

Answer 5

Pulmonary Blood flow problem that does not allow them to put enough blood into their lungs due to the Pulmonary Artery Stenosis.

Palliative:
Administer PGE1 to maintain the PDA open.

Question 6

Palliative procedure for patients that have difficulty getting blood into their lungs?

Answer 6

BT Shunt

Question 7

Corrective surgery for Tetralogy of Fallot patients?

Answer 7

•(Relief of Pulmonary Stenosis) through one of the following:

• Commisurotomy
• valvuloplasty
• valvectomy

- Resection of obstruction for 
  subvalvular stenosis
- Transannular Patch for 
  annular stenosis
• VSD Closure

Question 8

Pink Tets may be shunting from:

Answer 8

Left to right

Question 9

Pink Tets may or used to be treated by :

Answer 9

PA banding to offer just the right resistance as the aorta.

Question 10

What happened if you allowed a Pink Tet for a period of time with wide open blood flow to the lungs?

Answer 10

Irreversible Pulmonary Hypertension known as

“eisenmengers physiology”

Question 11

Another way of treating TOF besides a BT shunt?

Answer 11

Central Aorto-Pulmonary Shunt

from the PA to the Aortic Arch

Question 12

Watterson-Cooley Shunt for

Tetrology of Fellot

Answer 12

ascending
aorta to right pulmonary
artery anastomosis

Question 13

Cor Triatriatum

Answer 13

Failure of normal heart development of the heart where the pulmonary veins enter the left atrium. A 3rd atrium is developed and receives all pulmonary venous return (pulmonary venous
obstruction) and therefore has difficulty draining the lungs which results in

Question 14

Taussig Bing Complex

Answer 14

• Transposition of the Great Vessels.
• The PA overrides the
  VSD.
