LVAD
Also written as: LVAD — Left Ventricular Assist Device
Left Ventricular Assist Device, an implantable mechanical pump that supports circulation in patients with severe heart failure.
Full Definition
A Left Ventricular Assist Device (LVAD) is a surgically implanted mechanical pump designed to assist or replace the function of a failing left ventricle. The device draws blood from the left ventricle and pumps it into the aorta, thereby maintaining systemic circulation in patients with end-stage heart failure. LVADs can serve as destination therapy for patients who are not transplant candidates, as a bridge to heart transplantation, or as a bridge to recovery in cases of potentially reversible heart failure.
Usage
Usage note: Specify whether bridge-to-transplant, bridge-to-recovery, or destination therapy; may also see RVAD (right ventricular assist device).
In Context
- "The patient underwent LVAD implantation as destination therapy given his ineligibility for heart transplantation." — Surgical consultation note
- "Post-LVAD complications included pump thrombosis requiring anticoagulation adjustment." — Cardiothoracic surgery follow-up
