Short-term right heart bypass using high-flow or low-flow methods supports deairing and recovery during left ventricular assist device (LVAD) implantation. These techniques ensure adequate right heart function post-procedure.

Area of Science:

  • Cardiovascular Surgery
  • Medical Devices
  • Cardiopulmonary Bypass

Background:

  • Left ventricular assist devices (LVADs) are increasingly used as a bridge to transplant.
  • This has highlighted the need for temporary right heart support during LVAD procedures.
  • Such support is crucial for deairing the ventricular device and promoting right ventricular recovery.

Purpose of the Study:

  • To describe two distinct methods for short-term right heart bypass.
  • To evaluate the efficacy of these approaches in conjunction with LVAD implantation.
  • To provide functional right heart support and facilitate device deairing.

Main Methods:

  • Two approaches, high-flow and low-flow right heart bypass, are detailed.
  • Both methods utilize existing venous drainage and return blood to the pulmonary artery (PA) via a modified adult vent (AV) cannula.

  • High-flow uses a 0.25-in tube for up to 3.5 L/min; low-flow uses the cardioplegia line for 400-600 ml/min.

    • Main Results:

    • Both high-flow and low-flow methods were functionally successful.
    • The techniques allowed for effective support of the right heart.
    • Successful deairing of the left ventricular assist device was achieved.

    Conclusions:

    • Short-term right heart bypass is a viable strategy during LVAD implantation.
    • The choice between high-flow and low-flow depends on individual patient needs.
    • These methods facilitate right ventricular recovery and ensure proper device function.
