Area of Science:

  • Biomedical Engineering
  • Immunology
  • Hematology

Background:

  • Ventricular assist devices (VADs) are associated with significant systemic complications.
  • The blood-biomaterial interface is a key factor in host/device interactions.
  • Complications include bleeding, hemolysis, thrombogenicity, inflammation, infection, and immune compromise.

Purpose of the Study:

  • To review current literature on host/device interactions with ventricular support systems.
  • To explore the systemic complications arising from these interactions.
  • To provide insight into the role of cellular, humoral, and neurohormonal components.

Main Methods:

  • Literature review of studies on ventricular support systems and host/device interactions.
  • Analysis of biocompatibility research.

  • Examination of cytokine expression regulation.

    • Main Results:

    • Host/device interactions lead to humoral dyscrasias.
    • Complications manifest as bleeding, hemolysis, thrombogenicity, and increased infection risk.
    • Cellular, humoral, and neurohormonal factors critically regulate cytokine expression.

    Conclusions:

    • Systemic complications are inherent to ventricular support systems.
    • Biocompatibility research is vital for understanding and mitigating these adverse effects.
    • Further research is needed to fully address the complexities of host/device interactions.
