Milestones in artificial heart l.jpg

Milestones in artificial heart

1953, a heart-lung machine designed by Dr. John

Gibbon is used in a successful open-heart surgery,

demonstrating that an artificial device can

temporarily mimic the functions of the heart

1955, a team of scientists led by Willem Kolff,

tested their model in animals


Slide3 l.jpg

1964, the National Heart, Lung and Blood

Institute sets a goal of designing a total artificial

heart by 1970


Slide4 l.jpg

1967, Dr. Christiaan Barnard performs the first successful

human heart transplant. The patients, 53-year-old dentist

Louis Washkansky, dies 18 days after surgery in South

African


Slide5 l.jpg

In 1969, a team led by

Denton Cooley of the

Texas Heart Institute

successfully kept a human

patient alive for more than

sixty hours with their

model (temporary). The

patient gets a heart

transplant three days later

but then dies 1 ½ days

afterward


Slide6 l.jpg

In 1982, a team led by William DeVries of the University

of Utah implanted the Jarvik-7 into a patient named

Barney Clark, who survived with Jarvik-7 for 112 days

1982-1985, Dr. William DeVries carries out a series of

five implants of the Jarvik total artificial heart

William Schroeder, lived 620 days, dying in

August 1986 at age 54


Slide7 l.jpg

1994, the Food and Drug Administration approves the Left Ventricular Assist Device, which helps failing hearts continue to function

2000, A man in Isreal becomes the first recipient of the Jarvik 2000, the first total artificial heart that can maintain blood flow in addition to generating a pulse

2001, doctors at Jewish Hospital in Louisville, Ky., implant the first self-contained, mechanical heart replacement into a patient

Two recipient: Robert Tools & Tom Christerson


Robert jarvik l.jpg

Robert Jarvik Ventricular Assist Device, which helps failing hearts continue to function

He was born in Michigan

on May 11, 1946

In 1964, his father became

ill with heart disease and

had to have open heart

surgery


Robert jarvik9 l.jpg

Robert Jarvik Ventricular Assist Device, which helps failing hearts continue to function

Jarvik became very interested in medicine at that point and began to think about possible designs for artificial hearts that could help people like his father

He invented Jarvik-7 and Jarvik-2000

Prof willem j kolff l.jpg

Prof. Willem J Kolff Ventricular Assist Device, which helps failing hearts continue to function

He was born in Leiden,

Netherlands

Graduated from the

University of Leiden

In 1955, he implanted an

artificial heart into a dog

Tutor of Dr. Robert

Jarvik

1981, he applied to FDA


Dr william devries l.jpg

Dr. William deVries Ventricular Assist Device, which helps failing hearts continue to function

An American cardiothoracic

surgeon

Receiving his MD degree from the University of Utah in 1970

As a resident in cardiovascular/

thoracic surgery at Duke University Medical Center

Assistant professor of surgery at the University of Utah until 1984


Dr william devries13 l.jpg

Dr. William deVries Ventricular Assist Device, which helps failing hearts continue to function

Since 1984, he has been

director of the artificial heart

project of the Humana Hospital

Audubon in Louisville,

Kentucky

Performed the first successful

permanent artificial heart

implant for Barney Clark by

using an artificial device

designed by Dr. Robert Jarvik


Dr barney clark l.jpg

Dr. Barney Clark Ventricular Assist Device, which helps failing hearts continue to function

An 61year old retired

dentist from Seattle

First recipient of the

man-made artificial

heart on Dec 1, 1982 at

the Utah Medical

Center


Dr barney clark15 l.jpg

Dr. Barney Clark Ventricular Assist Device, which helps failing hearts continue to function

Six years before the transplant,

he had contracted a mysterious

viral infection, which made his

cardiac muscle flabby, weak

and swollen from a lack of

blood flow

Because of hypertension and

his age, he was not an

acceptable candidate at any

heart transplantation center


Dr barney clark16 l.jpg

Dr. Barney Clark Ventricular Assist Device, which helps failing hearts continue to function

He was introduced by his private doctor to Dr. Willim

DeVries

The meeting included visits to laboratories where the

Jarvik-7 was manufactured and the animal barn where

they observed calves/sheep with similar heart implants

He was given an 11-page consent form

There was no guarantee that the operation would

increase Clark’s life span, no guarantee he would regain

his independence


Dr barney clark17 l.jpg

The consent form stated “I recognize that if the artificial heart device fails, death or serious injury is the near certain result. I nevertheless accept the risk of substantial and serious harm, including death, implementation of the artificial heart device can be demonstrated


Dr barney clark18 l.jpg

Dr. Barney Clark Ventricular Assist Device, which helps failing hearts continue to function

He signed a consent form on Nov

30, 1982 at 9:52 p.m after being

interviewed by six members of a

special heart subcommittee at

University of Utah Medical Center

The surgery was scheduled at the

morning of Dec 2, 1982

However, he was immediately

rushed into the operating

room because of his deteriorating

heart on Dec 1, 1982 at 10:30 p.m.

Dr. Barney Clark Ventricular Assist Device, which helps failing hearts continue to function

He survived with Jarvik-7 for

112 days

A serious of complication

led to Clark’s death from

circulatory and multi-organ

collapse on March 23 at

10:02 p.m.

Tom Christerson, second recipient of AbiCor artificial heart are still alive for more than one year


Artificial hearts abandoned l.jpg

Artificial hearts abandoned Ventricular Assist Device, which helps failing hearts continue to function

By the end of the ’80s, the Jarvik devices had been

implanted to sustain patients waiting for transplants

Since then, development of an improved artificial heart

has continued

Scientists continue to work on designs for an artificial

heart that could provide a realistic, permanent option for

survival

Jarvik is now working on the Jarvik 2000, a thumb-sized

heart pump
