Abbreviations
- Left ventricular assist device (LVAD)
- Right ventricular assist device (RVAD)
- Biventricular assist device (BiVAD)
- Percutaneous ventricular assist device (pVAD)
- Intraaortic balloon pump (IABP)
- Total artificial hearts (TAH)
Definitions
- Mechanical pump device used to augment cardiac output for failing ventricle
- LVAD goal
- Diverting oxygenated blood from left heart into aorta, bypassing left ventricular function
- RVAD goal
- Diverting blood from right ventricle to pulmonary artery, bypassing right ventricular function
- FDA approval of 1st LVAD as bridge to transplant was in 1994
- Heartmate II, III and HVAD devices are only commercially FDA-approved adult ventricular assist device (VAD) options in North America
- SynCardia TAH is only FDA-approved device in its class
- Impella goal
- Transfer oxygenated blood via catheter tip in left ventricle to outlet in ascending aorta by axial flow
