A

mechanical and circulatory support and device elated complications

18
Q

A

LVAD or RVAD
BiVAD
continuous infusion of intravenous inotropes

19
Q

A

infusion of low dose single inotrope

6 months or younger

20
Q

2

A

Does not met higher criteria but suitable for transplant

21
Q

Inactive

A

Temporarily unsuitable for transplant

22
Q

Components of lung allocation score:

A
DOB
height and weight
lung diagnosis
functional status
diabetes
assisted ventilation
supplemental O2
MAP
6 minute walk distance
23
Q

Pulmonary Rehab recommendation:

A
minimum of 20 sessions three times/week or two times/week plus home
high intensity when possible
interval training
UE and LE training
endurance and strength
inspiratory muscle training
24
Q

Goal of preoperative rehab:

A

improve or prevent deteriorations of candidate’s physical condition
Endurance activities – limited to minimal levels of exertion or ADLs
30-40 min, 3-5x/wk

25
Why Alternative Therapies | Transplant Unsuitability
Did not meet criteria for organ system failure Contraindications limits potential for success Dec overall benefits for the pt Pt opted for more conservative surgical or medical management
26
Alternatives for Lung Transplant: | LVRS – Lung Volume Reduction Surgery
20-30% of volume of each lung is removed | Goal improve thoracic distention & chest wall mechanics
27
Alternatives for Lung Transplant: | Noninvasive ventilation or BiPAP
Tightly fitting nasal mask | Deliver positive airway pressure during inspiration & exhalation
28
Who is noninvasive ventilation or BiPAP indicated for?
pts with signs of respiratory failure despite max drug & O2 therapy
29
Alternative Therapies to Heart Transplant
VAD Home IV pharmacological mangement cardiomyoplasty
30
Most common VAD until transplant?
LVAD
31
Harvest of Donor Lungs
Pulmonary veins are detached from heart with cuff of left atrium Pulmonary arteries are transected Lungs removed en bloc, divided into separate right and left lungs
32
Heterotopic heart transplantation (HHT) – “piggyback”
Pt heart is not removed | Donor heart is connected via R/L atria
33
Orthotopic/biatrial technique
Recipient’s SA node is left intact, Donor & recipient’s atrial cuffs are sewn together 2 P-waves on ECG
34
Signs and Symptoms of acute rejection:
``` low grade fever increase in resting BP hypotension with activity myalgia fatigue decrease exercise tolerance ventricular dyshythmias ```
