Area of Science:

  • Cardiovascular Surgery
  • Biomedical Engineering
  • Medical Devices

Background:

  • The Jarvik 7 total artificial heart marked a significant advancement in mechanical circulatory support.
  • Left ventricular assist devices (LVADs) have gained prominence, overshadowing total artificial hearts.
  • LVADs are increasingly used for temporary support and permanent implantation.

Purpose of the Study:

  • To discuss the evolving role of ventricular assist devices (VADs) in treating heart failure.
  • To provide an overview of available VAD options.
  • To explore the future potential of implantable circulatory support devices.

Main Methods:

  • Review of the historical use of mechanical circulatory support devices.
  • Discussion of current trends in VAD technology and application.
  • Overview of different types of VADs and their functionalities.

Main Results:

  • Significant progress has been made in VAD technology for both temporary and permanent use.
  • A wide range of VADs exist, varying in complexity and cost.
  • The field is moving towards widespread adoption of implantable circulatory support.

Conclusions:

  • Implantable circulatory support devices are nearing a point of common clinical use.
  • VADs may offer outcomes comparable to or better than current cardiac transplantation.
  • The future of heart failure management will likely involve advanced mechanical support systems.
