LVAD
Pronunciation: L-VAD
Also written as: LVAD — left ventricular assist device
Left ventricular assist device providing mechanical circulatory support for patients with severe heart failure.
Full Definition
LVAD (left ventricular assist device) is a mechanical pump surgically implanted to support or replace the function of a failing left ventricle by drawing blood from the left ventricle and pumping it to the aorta. These devices may serve as bridge-to-transplantation therapy, bridge-to-recovery, or destination therapy for patients ineligible for heart transplantation. Modern LVADs are typically continuous-flow centrifugal or axial pumps that require specialized anesthetic management, anticoagulation protocols, and careful attention to preload, afterload, and pump speed settings during perioperative care.
Usage
Usage note: Distinguish from RVAD and BiVAD when documenting ventricular support therapy.
In Context
- "LVAD implantation was performed as bridge-to-transplantation therapy for end-stage cardiomyopathy." — Surgical procedure report
- "The patient's LVAD required speed adjustment during anesthetic emergence to maintain adequate flow." — Anesthesia care record
