Introduction

• The population of patients with end-stage heart
  failure has increased over the years, and the
  availability of donor organs has not be
  Sufficient.
• End-stage heart failure represents a highly
  morbid condition for the patient with limited
  treatment options.
• The treatment options are heart transplantation,
  heartlung transplantation or implantation of a
  Mechanical Circulatory Support Devices.

7

• If a patient waits until an organ becomes
  available for transplantation, they could need to
  wait months for that organ and therefore their
  condition could get worse.
• There two Types of MCS Devices
• 1. Ventricular Assist Devices (VAD) are use on
  Short terms to Complement Failing Hearts.
• 2. Total Artificial Heart (TAH) one available
  option when long-term support of both ventricles
  is required.

History

• Scientist and Engineers were aiming for a
  temporary support.
• The first TAH was implanted in an animal model
  and then in a human.
• Contributors to the development of the first
  artificial heart William Kolff, Don Olsen,
  Robert Jarvick and William DeVries.
• Lead to the implantation of the Jarvick 7
• The scientist implanted the Jarvick 7 on a
  61year-old man that died after 112 days.
• After the failure they tried implanting the
  Jarvick 7 in a 25-year-old, but just as bridge to
  transplantation and it functioned perfectly.

Present and Future Prespectives

• In August 2006, an artificial heart was implanted
  into a 15-year-old girl.
• It was intended to act as a temporary fixture
  until a donor heart could be found. Instead, the
  artificial heart allowed for natural processes to
  occur and her heart healed on its own.
• After 146 days, TAH was removed, and the girl's
  heart was able to function properly on its own. 

16

• Even though the TAH gives a viable alternative to
  the patients with end stage heart failure, the
  TAH have some disadvantages.
• Some of this disadvantages are that they dont
  fit all the patients, patients are tethered to
  the driver which interferes with quality of life,
  durability, complications such as infections, and
  lack of pressure flow compared to a normal heart.
  
• Scientists are working to decrease the size of
  the TAH and improve their function. 
• Some doctors are designing a continuous-flow TAH
  that has no valves or sensors.
