Insights

Percutaneously delivered ventricular assist devices (PVAD) offer a less-invasive mechanical support option for pediatric heart failure patients. This case series highlights biventricular PVAD use in adolescents post-transplant, demonstrating both challenges and potential for advanced heart failure management.

Area of Science:

  • Pediatric Cardiology
  • Mechanical Circulatory Support
  • Transplantation Medicine

Background:

  • Growing interest in percutaneously delivered ventricular assist devices (PVAD) for pediatric patients.
  • Heart transplant recipients are susceptible to graft rejection and acute heart failure.

Observation:

  • Two adolescent patients (16F, 18M) post-heart transplant presented with severe heart failure due to graft rejection.
  • Both patients received percutaneous Impella CP (LVAD) followed by Impella RP (RVAD) for biventricular support.
  • Despite PVAD support and medical management, one patient experienced multisystem organ failure and mortality.

Findings:

  • Biventricular PVAD support was successfully initiated in two adolescent heart transplant recipients.
  • While initial hemodynamic parameters improved, persistent CVP elevation and organ injury complicated management.
  • One patient required explantation within 4 days, progressing to total artificial heart and retransplantation; the other patient demised.

Implications:

  • Biventricular PVAD represents a novel, less-invasive mechanical support strategy for complex pediatric heart failure.
  • This approach may be applicable to older children and adolescents, expanding VAD options.
  • Careful monitoring and management are crucial due to potential complications in this vulnerable population.
