- The man who performed the first heart transplant came from
- a small town in the semi-desert scrubland of South Africa.
- Christiaan Barnard trained at Cape Town University in the
- early Forties. He was a quiet, well-liked, hardworking
- medical student - not a pacesetter, either academically or
- socially. In the late Fifties he went to Minneapolis to train
- under the eminent cardiac surgeon Walt Lilliehei. Once back
- in South Africa, he worked on straightforward cardiac
- surgery, and was in the forefront of all cardiac surgical
- development. He made a further visit to the States in the
- mid-Sixties to study their latest operative techniques. Before
- he did a human heart transplant, Barnard did many
- experimental operations on dogs. Dr Shumway, in the States,
- had announced his intention to do a heart transplant back in
- August 1967 and had established all the fundamental
- surgical principles involved. Dr James Hardy had
- transplanted a baboon's heart into a patient before that. But
- Chris Barnard was the surgeon who, on December 3, 1967,
- actually did the first one, and proved that a human heart
- transplant is possible. Since then, many thousands of heart
- transplants have been done. Barnard's second patient, Philip
- Blaiberg, lived for 594 days after the operation. The
- operation now ranks as a standard cardiac surgical procedure
- with a great many survivors over five years. Barnard would
- have been a first-class surgeon even if he hadn't performed
- the world's first heart transplant. He was the right man in
- the right place at the right time. It is a pity that rheumatoid
- arthritis cut short his surgical career
- @
- 2.2
- The heart of a 25-year-old woman, who had been killed in a
- car crash on Saturday night, was beating yesterday morning
- in the chest of a 56-year-old man in Groote Schuur hospital,
- Cape Town.
-
- The operation was the first transplant of a human heart. It
- lasted five hours. The patient, Mr. Louis Washkansky, was
- said later to be fully conscious and in very good condition.
- His blood pressure was normal.
-
- Professor Christian Barnard, who headed the surgical team, is
- well known to British colleagues as a dynamic leader and
- able surgeon. The feeling last night was that if he had been
- in charge the chances of success must be rated as high as in
- any pioneer operation.
-
- Mr. Washkansky had been admitted to hospital with cardiac
- failure and the surgeons had been waiting four weeks for a
- heart to transplant. Miss Denise Darvall died in the hospital
- after being injured in a car accident, and her father gave
- permission for her heart to be removed.
-
- It was not known in London whether compatibility tests had
- been made. This is standard procedure in kidney transplants
- and success in these depends largely on it. The tests used
- are analogous to blood group tests except that white
- corpuscles instead of red cells are used.
-
- REASON FOR OPTIMISM
-
- In kidney transplants between well-matched individuals the
- success rate a year after operation has reached between 75
- and 90 per cent. A heart transplant is more formidable as an
- operation, but the problem of compatibility may be less
- great. The reason for optimism in this respect is the greater
- simplicity of the heart.
-
- Professor Barnard said after the operation that the next few
- days would be vital. "The actual transplant was not really a
- problem, but the question of tissue rejection is the important
- one."
-
- Even between well-matched individuals, tissue rejection as a
- result of immunological reactions has to be controlled for
- some time afterwards. This is done by drugs borrowed from
- cancer research. There is a phase in the immunological
- response to alien tissue which involves the multiplication and
- division of cells.
-
- The drugs used prevent or reduce this. But in so doing they
- limit also the production of white cells which are an
- important defence against infection. There is therefore an
- added risk from infection and use of the drugs is tapered off
- progressively.
-
- A heart surgeon in London said to me: "I hope the operation
- is a success, not only for the patient's sake, but because we
- may then hope to get more support for what we are all of us
- trying to do."
-
- It would mean much to the relatives of the woman to know
- that her heart had not been taken from her body in vain.
- @
- 2.4
- Louis Washkansky, the most publicized hospital patient in
- the world, died yesterday.
-
- The cause of death was pneumonia, and not rejection by his
- body of the girl's heart, transplanted into him 18 days
- previously.
-
- Professor Christiaan Barnard, the heart surgeon who carried
- out a heart transplant operation in South Africa, said on BBC
- Television last night that although his medical team were
- very disappointed by the death of Mr. Washkansky, there
- were some "very encouraging features".
-
- "The organ that failed was not the heart, which continued to
- function well. We are disappointed but not discouraged and
- we will go ahead with a second transplant" said Professor
- Barnard.
-
- ETHICAL ISSUES
-
- The Washkansky transplant and the resulting publicity
- raised several ethical questions, which trouble both doctors
- and laymen. Here Our Medical Correspondent discusses
- them.
-
- The tragic, though not unforeseeable, death of Mr.
- Washkansky in the Groote Schuur Hospital, Cape Town,
- brings to a close an episode which throughout has raised
- more anxiety than enthusiasm.
-
- In isolation, transplantation of a human heart raises no moral
- or ethical problems, but no such operation can ever be
- viewed in isolation. If carried out, it inevitably raises a host
- of direct and indirect problems, such as the dividing line
- between life and death, euthanasia, and the cost of life; a
- fascinating, if devastating triad which should give lifetime
- employment to every moral philosopher and theologian in
- Christendom.
-
- That the medical profession is well aware of the problem is
- shown by the current publication of a symposium on "The
- cost of life" in the Proceedings of the Royal Society of
- Medicine. This is but one of a series of such discussions that
- have been published in recent years, but it is of particular
- interest because the participants are almost entirely
- practising doctors discussing problems they have actually
- encountered.
-
- The title of the symposium is deliberately provocative.
- Though no answer is given to it, even the most superficial
- consideration of the various papers indicates how strongly
- responsible members of the profession appreciate the
- problems involved. By and large, most of them accept that
- there is a problem but find it difficult to face up to its full
- implications.
-
- Three random samples, to use technical jargon, may be taken
- to exemplify the range of the problems reviewed. The first is
- from the introductory paper on the so-called artificial
- kidney, or intermittent dialysis as it is technically known. "If
- all potential candidates up to age 54 were treated on
- intermittent dialysis, about $30m. per annum of direct costs
- and over 10,000 staff might be tied up in treating 23,000
- patients. The indirect cost of treating these patients,
- particularly the unsuitable ones, defy computation."
-
- The second is the episode reported by an Oxford doctor" of a
- colleague of his who, in the first stage of cancer, extracted
- from the friend who treated him, the promise to give him a
- fatal injection when things became bad. Things became bad,
- and the patient, frightened and suspicious, refused to have
- even the injections which would be ordinarily prescribed."
-
- The third is the hale and hearty octogenarian woman doctor,
- well known for her work for the elderly in the days of the
- London County Council, who commented that "there was
- nothing more discouraging, and causing more rapid
- deterioration, than to give the patient the idea that his doctor
- was no longer interested in him and that he might as well be
- let go because nothing further could be done.... It was not
- only medically wrong, but it was psychologically cruel to
- inflict such an idea on any patient."
-
- TRANSPLANTS
-
- On the question of transplants, Lord Kilbrandon, Lord of
- Sessions in Edinburgh, said that at present the law seriously
- handicapped surgeons. Asking permission from next of kin
- was a very unpleasant thing to have to do and as far as the
- kidneys were concerned, there was a great hurry. Half an
- hour was all the time they had. He thought the law should
- be altered so that an organ could be taken if there was no
- reason to believe that next of kin would mind or that the
- person would have minded.
-
- Dr. Adrian Kantrowitz of the Maimonides Hospital, Brooklyn,
- said that he had concentrated his surgical effort on children
- because they had felt that certain medical problems might be
- easier to work out using the bodies of children who had died
- from congenitally deformed brains whose hearts were good.
-
- Professor J. Hamburger, Professor of Medicine, University of
- Paris, who has carried out 86 kidney transplants thought the
- South African operation was only the beginning of a very
- important story. He described the problems involved in
- selecting donors and how the results of an operation
- improved as the selection improved.
-
- Dr. Barnard said he saw a very bright future for organ
- transplantation.
-
- The speakers seemed to agree on the moral question of
- deciding when a person was dead. It was necessary that one
- team of doctors should pronounce a person dead and another
- team should remove any organs. There was nothing
- unethical in taking a part from a dead person, provided they
- were sure he really was dead.
-
- In the United States the laws varied between states, but the
- basic rule was that a person should give consent and he
- should understand the consent he was giving before any
- organs were removed.

- Surgeons led by Professor Christiaan Barnard successfully
- transplanted the heart of a young coloured man into the
- body of a white dentist in Cape Town yesterday.
-
- Professor Barnard said later that the operation had gone
- better than that on Mr. Louis Washkansky last month. The
- transplanted heart had begun beating by itself without
- electric shock. Last night the patient recovered
- consciousness.
-
- The man who received the transplanted heart was Dr. Philip
- Blaiberg, and the donor was Mr. Clive Haupt, aged 24, who
- died of cerebral haemorrhage. Professor Barnard was
- assisted by the same team which helped during the
- Washkansky operation.
-
- Today's operation started soon after 10.30 a.m. and ended
- about 4.30 p.m. (South African time). Again, the critical time
- for rejection symptoms will be in about a fortnight.
-
- Dr. Blaiberg had been forced to retire from dental practice
- because of a progressively weakening heart. During his
- recent visit abroad, Professor Barnard repeatedly said that
- he was anxious to return to Cape Town because Dr. Blaiberg's
- condition was deteriorating.
-
- Mr. Haupt, a Cape Town factory worker, was married three
- months ago. He collapsed on the beach during the New Year's
- Day holiday. The fact that Mr. Haupt is coloured answers
- questions that had been asked about the possibility of
- apartheid being a complicating factor here in such operations.
-
- Mr. Haupt was transferred from the suburban hospital at
- Wynberg to Groote Schuur hospital (where the operation took
- place) when it was seen that the brain haemorhage made his
- chances hopeless. He underwent the required compatibility
- tests and at one stage, it is understood, his heart stopped,
- then revived. He was kept alive for the last few hours by
- "artificial ventilation".
-
- Professor Barnard arrived home yesterday after what must
- have been an exhausting visit to America, returning by way
- of London. The whole heart transplant team had been ready
- for his return and for the arrival of a possible donor.
-
- After the Washkansky operation the hospital had some
- difficulty through the presence of a large number of
- journalists. The Blaiberg family, however, are guarding their
- privacy far more carefully. Mr. Washkansky's death through
- infection must also induce the medical team to observe even
- more strictly a virtual quarantine of the patient until the
- danger of rejection is over.
-
- Today's operation was the third of its kind. A baby died in a
- New York hospital last month soon after receiving a heart.

- Dr. Christiaan Barnard, who last December performed the
- first transplantation of the human heart at the Groote Schuur
- Hospital in Cape Town, takes issue with his critics in an
- interview with the German newspaper Welt am Sonntag.
-
- Dr. Barnard is concerned particularly with refuting the
- arguments of Professor Werner Forssmann, a prominent
- German surgeon and Nobel Prize winner, who has strongly
- criticized the heart transplant operation on ethical, legal, and
- medical grounds.
-
- Dr. Barnard's main answer is that the transplantation of the
- heart is no different from that of other organs, like the liver.
- "Once one has removed a liver from the body of the donor
- there is no artificial liver one can put in."
-
- At least 11 or 12 liver transplantations must have been
- performed, Dr. Barnard says, and, so far as he knows, only
- four of the patients concerned are still alive. Yet nobody has
- criticized these operations. The fact that the first heart
- transplantation was carried out in South Africa may have
- something to do with the hostile reaction of some sections of
- the medical profession, Dr. Barnard feels.
-
- Professor Forssmann argued that medical knowledge of the
- immunology of transplanted organs was insufficient to justify
- the kind of operation being undertaken at Groote Schuur. Dr.
- Barnard comments: "Does he mean that no more
- transplantations should be carried out anywhere in the
- world?"
-
- Professor Forssmann also drew a comparison between the
- Groote Schuur operations and the activities of Professor Karl
- Gebhardt, one of the most notorious of the Nazi surgeons who
- used the bodies of concentration camp prisoners for "medical
- experiments."
-
- Dr. Barnard dismisses as "nonsense" the allegation that the
- Groote Schuur operations had shown disregard for medical
- ethics and humanity. The doctor's task, he states, is to treat a
- patient until there is nothing more that can be done for him.
- This applies equally whether the patient is the receiver or
- the donor of an organ.
-
- Dr. Philip Blaiberg, the heart transplant patient, was allowed
- out of bed for the first time today and sat in a specially
- prepared and sterilized chair.
-
- A medical bulletin from Groote Schuur Hospital, where he
- received his new heart 12 days ago, said he was "bright and
- cheerful and eating well."
-
- The condition of his heart was satisfactory and his sore
- throat had almost completely cleared up.

- Dr Christiaan Barnard, the South African cardiac surgeon, said
- in Cape Town today that he would use chimpanzees' hearts in
- future transplant operations after the failure last night of an
- operation involving a baboon's heart.
-
- An unnamed Italian woman, aged 25, died in the Groote
- Schuur Hospital early today, two and a half hours after
- professor Barnard attached the heart of a baboon to her
- failing heart.
-
- Dr Barnard told a press conference today that the baboon's
- heart had proved to be too small to carry the woman's
- circulation alone when her own heart began failing. The
- operation would have been successful if he could he could
- have used a human heart, but none was available.
-
- He explained that a chimpanzee's heart was larger than that
- of a baboon and would therefore be able to carry a larger
- load of the patient's life. It was the first time he had carried
- out an operation using a baboon's heart as a "booster"
-
- Earlier his team had carried out open heart surgery to
- replace a previously inserted aortic valve with a larger one,
- but they found that the patient's heart failed each time they
- switched off the heart-lung machine. Dr Barnard pointed out
- that the machine could not be used indefinitely as it was
- destroying blood elements.
-
- After all other means had failed, only one possible solution
- remained - a heart transplant. No human donor was
- available, he added, "but I had a baboon with the same blood
- group as the patient, and I transplanted the heart. The
- baboon was one of two kept at Groote Schuur.
-
- As soon as its heart had been inserted the patient was taken
- off the heart-lung machine. For a while both hearts were
- working well and the patient briefly regained consciousness.
-
- "Then the patient's won heart deteriorated again and
- eventually we couldn't get it to restart and the baboon heart
- just couldn't cope with carrying the full circulation and the
- patient died."
-
- He had hoped, he said, that the baboon heart would have
- been able to assist circulation for two to three days. In the
- meantime either the patient's own heart would have been
- able to cope alone or else a human donor would have been
- found.
-
- He felt the operation might have succeeded if the baboon
- transplant had been carried out sooner, "but it was a new
- process and we tried to do everything we know first".
-
- The first attempted animal-human heart transplant took
- place in 1964, when Dr James Hardy, of the University of
- Mississippi, stitched the heart of a chimpanzee into a 68-year
- old man. He survived for only two hours.

- Britain's first artificial heart transplant patient yesterday
- squeezed the hands of his doctor and his nurse as he began
- to recover from the long and complex operation at Papworth
- Hospital near Cambridge.
-
- Mr Francis Wells, one of two surgeons who carried out the
- operation, lasting five hours, 20 minutes, over the weekend,
- said at the hospital that the patient was in a very good,
- stable condition and had signalled to his wife and medical
- staff that he was comfortable.
-
- The man, aged 40 and yet to be named, was receiving lots of
- fluid and would shortly be able to eat.
-
- Mr Terence English, the other surgeon, said the 13-member
- medical team wanted to replace the plastic and metal heart
- as soon as possible when a suitable natural one had been
- found. Ideally that would be within the next week or so
- when the patient had recovered from the immediate effects
- of the first operation.
-
- Mr English said the patient had suffered three heart attacks
- in the past three years, the most recent in September. When
- the decision to use a Jarvik-7 artificial heart was taken last
- week, the patient knew he was very seriously ill and the
- medical team thought he had no more than one or two days
- to live.
-
- Now that he had been fitted with an artificial heart he would
- have priority among the 28 patients on the waiting list for
- heart transplants at Papworth.
-
- Mr English said that clotting and the possibility of a stroke
- were the most likely immediate dangers to the patient's
- health. But he was being given drugs to thin his blood and
- he had experienced no severe bleeding problems to date.
- Rejection was not a problem with artificial hearts.
-
- Mr English said the operation was a little more involved than
- a normal transplant. As a result, and because the team was
- less familiar with the surgery involved, it had taken 20-30
- per cent longer than usual.
-
- Mr English said that the cost of the artificial heart-between
- 12,000 dollars (£8,000) and 15,000 dollars (£10,000)-was
- being borne by the American company which had pioneered
- the development of the artificial heart, as part of a 400,000
- dollar programme for Papworth.
-
- That included five artificial hearts as well as all the complex
- compressed air system for circulating the blood and various
- monitors for tracking the patient's health.
-
- The Papworth team had decided not to have more than one
- patient fitted with an artificial heart at any one time, Mr
- English said. That was because of the constant nursing and
- technical supervision required.
-
- Mr English said that Papworth regarded the implantation of
- an artificial heart as a temporary device for patients who
- might otherwise die if a suitable natural organ was not
- available.
-
- Experience in the US had shown that permanent implants of
- artificial hearts were not successful in the long term.
-
- The first patient to receive one-Dr Barney Clark, an
- American-died 112 days after his operation in December
- 1982. By August of this year, the first five men to be given
- permanent artificial hearts had died-the last being Mr
- William Schroeder of Louisville, who suffered several strokes
- before dying 620 days after his operation.
-
- The artificial heart is powered by a huge air compressor and
- critics have questioned what kind of life a patient can enjoy
- linked to such a device.

- Dr Christian Barnard, the pioneer of heart transplants, is
- retiring at the age of 61 because of rheumatoid arthritis in
- his hands. He will leave his position as chief specialist in the
- department of cardiac surgery at Groote Schuur hospital,
- Cape Town, towards the end of the year.
-
- On December 7, 1967, Dr Barnard announced the world's first
- heart transplant, that of an 18-year-old road accident victim,
- into the chest of an ailing diabetic, Dr Louis Washkansky, a
- dentist, who was 53 and lived with the new heart for 18
- days.
-
- Five years later he developed the so-called "piggy-back"
- technique in which a donor heart is transplanted to beat next
- to the patient's own ailing organ. In 1977, he carried out the
- world's first baboon to human heart transplant but a year
- later vowed not to perform such an operation again. Some of
- his more than 50 patients lived for more than 12 years with
- their new hearts.
