Cardiac surgeries

Question 1

What is an intra aortic balloon pump (IABP) used for?

Answer 1

Reduces myocardial oxygen demand, therefore increasing CO

Question 2

When does an IABP deflate?

Answer 2

systole (reducing afterload)

Question 3

When does an IABP inflate?

Answer 3

diastole (increases blood flow to coronary arteries

Question 4

What can an IABP be used to treat?

Answer 4

Cardiogenic shock

Question 5

What is coronary revascularization (CABG)?

Answer 5

It is a palliative treatment where new vessels are used to transport blood between aorta to distal area of occlusion.

Question 6

What is the most common vessel used in CABG?

Answer 6

internal mammary artery

Question 7

Who would CABG surgery benefit (prolong life)?

Answer 7

• -Left main CAD

- -3 vessel disease

Question 8

What is a MIDCABG?

Answer 8

It is a minimally invasive bypass grafting. The # of grafts are restircted.

Question 9

What is OPCABG?

Answer 9

Off pump CABG surgery to reduce length of stay

Question 10

What is a patient at risk for after a OPCABG?

Answer 10

stroke within 48-72 hours post op

Question 11

What does an LVAD do?

Answer 11

Supports left side of heart (LA and femoral artery)

Question 12

What does RVAD do?

Answer 12

supports the right side of heart (RA and PA cannulated)

Question 13

What is Extracorporeal Membrane Oxygenation (ECMO)?

Answer 13

Mechanical circulatory support for severe acute respiratory/cardiac failure.

Question 14

What is the action of ECMO?

Answer 14

Deoxygenated blood diverted from vascular system, it is oxygenated outside of body, then returned to vascular system.

Question 15

What does a VV ECMO support?

Answer 15

Respiratory only

Question 16

What does VA ECMO support?

Answer 16

Respiratory and cardiac support

Question 17

What are post-op considerations with Dynamic Cardiomyoplasty?

Answer 17

–do not cardiovert (potential damage to flap)
–Do not stimulate latissmus dorsi for 2 weeks
Monitor CK levels (increasing= flap failure)
