ventricular assist device weaning
Systematic process of gradually reducing mechanical circulatory support to assess native heart function recovery.
Full Definition
The carefully monitored process of progressively decreasing support from a ventricular assist device to evaluate the recovery of native cardiac function. This process involves stepwise reduction of device flow rates while continuously monitoring hemodynamics, cardiac output, and end-organ function. Anesthesiologists play a crucial role in managing the complex hemodynamic changes and potential complications during this critical period.
Usage
Usage note: Often abbreviated as 'VAD weaning' in clinical notes.
In Context
- "The patient tolerated ventricular assist device weaning well with stable hemodynamics at 50% flow." — ICU progress note
- "Ventricular assist device weaning was attempted but had to be aborted due to declining cardiac output." — Anesthesia record
