Mechanical circulatory assist devices support advanced heart failure by replacing failing ventricle function. Newer axial and centrifugal pumps offer alternatives to heart transplantation.

Area of Science:

  • Cardiovascular Surgery
  • Biomedical Engineering
  • Medical Devices

Context:

  • Advanced heart failure necessitates mechanical circulatory support.
  • Mechanical circulatory assist devices (MCADs) substitute failing ventricle function.
  • MCADs are crucial for bridging patients to heart transplantation.

Purpose:

  • To review the evolution of mechanical circulatory assist devices.
  • To discuss the shift from pulsatile to non-pulsatile flow pumps.
  • To highlight the emergence of axial and centrifugal pumps.

Summary:

  • Historically, pulsatile flow assist devices (pneumatic, electro-mechanical) were used.
  • A new generation of implantable assist devices provides non-pulsatile flow.
  • The DeBakey axial pump pioneered this new generation, with other axial and centrifugal pumps now developing.

Impact:

  • Mechanical circulatory assist devices are increasingly considered definitive treatments.
  • Advancements in pump technology offer viable alternatives to heart transplantation.
  • The development of axial and centrifugal pumps expands therapeutic options for heart failure patients.
