test 5 palliative shunts and procedure reviews

Question 1

Goals of Palliative Shunts

Answer 1

• Increase pulmonary blood flow
• Decrease pulmonary artery blood flow
• Improve mixing
• Reduce ventricular work

Question 2

Classic Blalock-Taussig shunt

Answer 2

• Shunt to Increase Pulmonary Blood Flow

- Subclavian to PA

Question 3

Modified Blalock-Taussig shunt

Answer 3

• Shunt to Increase Pulmonary Blood Flow

- Subclavian to PA (Gore-Tex graft)

Question 4

Central shunt

Answer 4

• Shunt to Increase Pulmonary Blood Flow

- Ascending aorta to main PA (Gore-Tex graft)

Question 5

Waterson shunt

Answer 5

• Shunt to Increase Pulmonary Blood Flow

- Ascending aorta to RPA

Question 6

Pott’s shunt

Answer 6

• Shunt to Increase Pulmonary Blood Flow

- Descending aorta to LPA

Question 7

Brock shunt

Answer 7

• Shunt to Increase Pulmonary Blood Flow

- Pulmonary valvotomy, closed

Question 8

Blalock-Hanlon shunt

Answer 8

• Shunt to Increase Mixing

- blade septectomy – cath lab procedure

Question 9

Rashkind shunt

Answer 9

• Shunt to Increase Mixing

- balloon septostomy

Question 10

Open Atrial Septectomy

Answer 10

• Shunt to Increase Mixing

- usually a concomitant procedure

Question 11

Balloon Septostomy

Answer 11

• Another Palliative Procedure
• Balloon septostomy is the widening of a foramen ovale, (PFO), or ASD via cardiac cath (or bedside) using a balloon)
• This procedure allows a greater amount of oxygenated blood to enter the circulation (IMPROVES MIXING)

Question 12

Shunts to Decrease Ventricular Work

Answer 12

• Bi-Directional Glenn Shunt
