Artificial Heart Devices and Transplants

Artificial heart devices and heart transplants are two key treatments for end-stage heart failure, a condition in which the heart is no longer able to properly pump blood. Both treatments have advantages and disadvantages, and the therapy chosen is based on the patient's individual medical condition and needs.

1. Artificial Heart Devices (Ventricular Assist Devices - VADs):

  • Ventricular Assist Devices (VADs) are mechanical pumps surgically implanted in the patient's chest to assist the heart in pumping blood more efficiently.
  • VADs are utilized as a bridge to transplant for patients waiting for a heart transplant or as destination therapy for those who are not transplant candidates.
  • Depending upon which part of the heart is failing, they can be used in the left ventricle (LVAD), right ventricle (RVAD), or both (BiVAD).
  • Vascular access devices (VADs) may greatly improve the quality of life for patients with severe heart failure, allowing them to restore some level of normalcy while awaiting transplant or as a permanent solution.
  • VADs, on the other hand, require constant monitoring and management, and complications such as infection and clot formation may occur.

2. Heart Transplants:

  • A heart transplant includes replacing a sick or failing patient's heart with a healthy donor heart.
  • Heart transplants are normally considered for patients with end-stage heart failure who have failed all other treatments and have a reduced life expectancy.
  • A notable constraint is the scarcity of acceptable donor hearts, and patients are sometimes forced to wait on transplant waiting lists for extended periods of time.
  • Following a heart transplant, patients must take immunosuppressive medications for the rest of their lives to prevent the new heart from being rejected.
  • Heart transplants can provide many patients with a longer and better quality of life, but there are hazards associated with the surgery and long-term immunosuppression.
