The Artificial Heart VD October 30, 2007 Chemistry 51
Abstract Researched the advantages of a man-made artificial heart.
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? • 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 • 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 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 • 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 • 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 • 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 • 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 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.
