What are two types of MCS (mechanical circulatory device)
- TAH (Total artificial heart)
- VAD (Ventricular Assist Device)
What are the components of VAD
- Power source (electrical or pneumatic)
- Driveline (Transfer power between controller and pump)
- Controller
- Pump (move blood for circulation)
What is the most used VAD
- LVAD (Left ventricular assist device)
What type of pumps for each generation of VAD
- First generation: pulsatile
- 2nd and 3rd gen: Rotary pump
Which type of pump is better for VAD and why
- Rotary pump
- Because it has single rotating, lightweight, more stable and less complicated
What total artificial heart is the first and only FDA approved
Cardiowest from Syncardia
What are some advantages of Cardiowest
- Pulsatile flow
- Lightweight
- Completely replaces native ventricles and all four valves.
- Portable Driver (FDA approved in 2014)
What are the components of Cardiowest
- 2 PU chambers, 4 tilting disc MHVs
What is AbioCor TAH
- 1st fully implantable TAH
- Approved by FDA in 2006
