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.

Preoperative management

Patient evaluation

System	Considerations
Airway
Neurologic
Cardiovascular	Critically low EF (15-20%) is not atypical. May also have underlying CAD, pulmonary HTN, and Grade 3 RHF
Pulmonary
Gastrointestinal

Endocrine

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
• TEE setup

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
• TEE

Induction and airway management

Pre-induction arterial line typically indicated. Very careful titrated induction due to critically low EF.
