Abstract
Abstract

Researched the advantages of a man-made artificial heart.


Introduction
Introduction

  • An artificial heart is a medical instrument that is was created in the 1950’s.

  • The estimated cost is $150,000 per implanted artificial heart, which can increase the U.S. medical bill by anywhere from $2.5 to $3 million (Jarvik & Callahan, 1986).

  • The use of an artificial heart to replace heart transplants is controversial.


What is an artificial heart
What is an artificial heart?

  • An artificial heart is a man-made device that is implanted into the body and replaces a person’s biological heart (Wikipedia).

  • An artificial heart is representative of modern technology in medicine.


History
History

  • Robert Jarvik created and experimented with the first artificial heart in the 1950’s.

  • Jarvik received a patent for his work in 1963.

  • The first implantation of an artificial heart was done in April 4, 1969 at the Texas Heart Institute in Houston (Wikipedia, 2007).

  • The first artificial heart was limiting but it allowed the patient enough mobility and peace to leave the hospital.

  • Today, some researchers believe that the artificial heart can be made as much if not more reliable than human heart transplants (Beltrame, 2002).


Jarvik 7
Jarvik 7

  • Jarvik 7 was the first artificial heart.

  • The first patient received the heart in 1982 and consequently died 112 days later from technical problems.

  • It took years to conquer, but the problems associated with the original Jarvik 7 have been worked out in order for the heart to benefit others.

  • It can support circulation and improve health in even extremely sick people (Jarvik & Callahan, 2007).


Jarvik 2000
Jarvik 2000

  • The Jarvik 2000 is an intraventricular artificial heart pump that was created from the original artificial heart. This pump is placed inside a biological heart and is used in major cases of heart failure while the patient waits for a real heart transplant.

  • The Jarvik 2000 is currently being used in Europe but has not yet been submitted for use in the U.S.


Benefits from the use of an artificial heart
Benefits from the use of an artificial heart

  • There is always a higher demand for heart transplants compared to the number of hearts available. An artificial heart will lower the need for heart transplants (Wikipedia).

  • With an artificial heart, patients will not need to go through the tests and trouble as they would to find a match for a human heart.

  • Very little medical follow-up is needed with an artificial heart (Beltrame, 2002).

  • A new artificial heart may last and produce more productivity than a used human heart.


Con s resulting from the use of an artificial heart
Con’s resulting from the use of an artificial heart

  • Technical problems associated with the artificial heart may result in death (Jarvik & Callahan, 2007).

  • An artificial heart is a foreign object to the patients body and it may be rejected (Wikipedia).


Procedure
Procedure

  • The native heart is removed from the patients body.

  • Assisted devices are used in order to keep the patient alive.

  • Similar procedures and techniques from human heart transplantation are used.

  • The artificial heart is implanted and complete.


Conclusion
Conclusion

Using an artificial heart in medical procedures is a controversial issue. However, the demand for real hearts is growing and the supply is not. Using an artificial heart may be beneficial to many because it can help save lives.
