A ventricular assist device (VAD) is a pump designed to assist the left or right ventricle in severe heart failure. These devices may help the left ventricle (LVAD), the right ventricle (RVAD), or bilateral ventricles (BiVAD). The device may be placed as a permanent solution or as a bridge to cardiac transplant.
Overview
Indications
Severe heart failure
Surgical procedure
LVAD
Surgeons will perform sternotomy for exposure and either cardiopulmonary bypass (CPB) or extracorporeal membrane oxygenation (ECMO). The device is placed at the apex of the left ventricle with an outflow graft anastomosed to the ascending aorta.

Labs and studies
Review cardiac studies including TTE, cardiac catheterization, etc.
Operating room setup
- Infusions: norepinephrine and epinephrine
- Also can consider infusions for insulin, dexmedetomidine, ketamine, cefazolin, TXA, heparin
- Arterial line setup
- Central line setup w/ PA catheter
- TEE setup
Patient preparation and premedication
Regional and neuraxial techniques
N/A
Intraoperative management
Monitoring and access
- Arterial line monitoring
- Central access
- large bore catheter (e.g. Cordis, MAC, etc)
- Infusion line (e.g. single lumen catheter)
- CVP monitoring
- PA catheter monitoring
- TEE
Induction and airway management
Pre-induction arterial line typically indicated. Very careful titrated induction due to critically low EF.
Positioning
Supine
Maintenance and surgical considerations
- CPB often used (full heparinization), though cardioplegia can usually be avoided
- For LVAD, as RPMs are increased, right heart may struggle to keep up with increased cardiac output
- Consider hyperventilation, FiO2 100%, inhaled nitric oxide, milrinone, dobutamine for RV contractility augmentation
- Aortic root vent and Trendelenburg after VAD is inserted to avoid air embolism
Emergence
Postoperative management
Disposition
ICU, typically remain intubated
