LVAD for Non-Cardiac Surgery

Anesthetic management of durable continuous-flow LVAD patients presenting for elective or emergency non-cardiac procedures

Continuous-flow LVAD patients are preload-dependent and afterload-sensitive; maintain euvolemia, avoid hypertension and elevated PVR, and coordinate with the VAD team before induction.

If you forget

HEADLINE: Call VAD coordinator FIRST; bring backup controller and batteries to the OR.

Board trap
Examiner asks: 'Why is the pulse pressure narrow or absent in a patient on a continuous-flow LVAD, and what should you monitor instead?' Answer: the LV is unloaded so the aortic valve may never open (the 'most extreme example' of flow-dependent valve change per ASE/EACVI 2017) — monitor MAP and LVAD flow/PI, not SpO2 or SBP.

Key numbers

  • MAP ≥60–65 mmHg or SBP ≥90 mmHg intraoperatively to reduce organ-injury risk (AHA/ACC 2024)
  • PAPi <1.85 in HF patients undergoing LVAD implantation predicts postop RV failure (AHA 2023)
  • PAPi ≤0.9 in AMI-CS is the concerning cutoff for RV failure (AHA 2023)
  • Normal continuous-flow LVAD output ≈4–6 L/min; flow falls as MAP/SVR rises
  • Class 1 (COR 1, C-EO) recommendation to coordinate elective NCS timing with VAD team (AHA/ACC 2024)
