Investigations Into The Haemodynamic And Metabolic Effects Of Brain Death

First Successful Transplant Of Pig Heart To Human Patient Performed In Maryland

This alerted the team to the fact that brain death must have a detrimental effect on myocardial function, and led to extensive investigations into the haemodynamic and metabolic changes during and after brain death, and the implications of these changes. This work was the first comprehensive study investigating the effects of brain death.1214 The major haemodynamic changes that take place as brain death was developing, some of which had been previously recorded by Harvey Cushing in 1902, were monitored.

It was documented that these could have a detrimental effect on subsequent myocardial function and were sometimes associated with histopathological features of myocardial injury. Previously unrecognised major endocrine changes that occur following brain death were documented. These include a massive catecholamine surge and a depletion of thyroid hormones and insulin, and other neuro-hormonal effects. These were associated with a loss of myocardial energy stores and other detrimental effects on cardiac function. Experimental studies in baboons indicated that aerobic metabolism soon ceases after brain death, and life is sustained by anaerobic metabolism.15

Brain Death And Ethical Issues

As previously mentioned, there were no laws relating to brain death at the time of the first transplant. This undoubtedly helped to accelerate the growth of bioethics and to wrestle from the medical profession the monopoly over medical ethics, which they previously held. In February 1968, three months after the first heart transplant, a bill was introduced in the US Congress to establish a commission to assess and report on the ethical, legal, social and political implications of medical advances. It was evident that transplantation had raised serious ethical and legal questions for society.

Doctors were still very much committed to the view that the profession should make the decisions about contentious issues such as the moment of death and when to stop certain treatment. Most of the medical witnesses who appeared before the congressional hearings were opposed to the bill. Many did not resent input from philosophers or theologians but most felt that doctors ought to retain control and have the final say. None was more outspoken than Christiaan Barnard whose opposition to the proposal was unqualified, almost nasty, perhaps reflecting the fact that in South Africa a doctors authority was still unchallenged or that he was not dependant on Congress or the National Institute of Health for funding.

The Second And Beyond

Three days after Barnards first, Kantrowitz from Maimonides Medical Center in Brooklyn, New York performed the second. The donor heart was retrieved from an anencephalic donor and transplanted to a 17-day-old newborn with a severe Ebsteins anomaly. Albeit the formidable challenge proffered by a very young age of the recipient, Kantrowitz performed the heart transplantation using hypothermic circulatory arrest, achieving spontaneous sinus rhythm 10 minutes after the transplantation. Six and half hours later, the baby developed severe respiratory and metabolic acidosis and in spite of exhaustive resuscitation measures, the infant succumbed .

Pig To Human Heart Transplants ‘possible Within Three Years’

Pioneer UK surgeon Sir Terence English says adapted organs could transform treatment

Adapted pig hearts could be transplanted into patients within three years, according to a report citing the surgeon who pioneered heart transplantation in the UK.

On the 40th anniversary of the first successful heart transplant, Sir Terence English told The Sunday Telegraph that his protege from that operation would try to replace a human kidney with a pigs this year.

If the result of xenotransplantation is satisfactory with porcine kidneys to humans, then it is likely that hearts would be used with good effects in humans within a few years, the 87-year-old said. If it works with a kidney, it will work with a heart. That will transform the issue.

The anatomy and physiology of a pigs heart is similar to that of a humans, so they are used as models for developing new treatments. Hopes for a successful heart attack treatment were raised in May after a genetic therapy showed promise in pigs.

An international team of researchers, including UK scientists, found that delivering a small piece of genetic material called microRNA-199 into a heart damaged by an attack caused cells to regenerate.

Myocardial infarction, caused by the sudden blocking of one of the coronary arteries, is the main reason for heart failure. Survivors are often left with permanent structural damage to their heart.

First Human Heart Transplant

25 Beautiful First Heart Surgery

On December 3, 1967, 53-year-old Louis Washkansky receives the first human heart transplant at Groote Schuur Hospital in Cape Town, South Africa.

Washkansky, a South African grocer dying from chronic heart disease, received the transplant from Denise Darvall, a 25-year-old woman who was fatally injured in a car accident. Surgeon Christiaan Barnard, who trained at the University of Cape Town and in the United States, performed the revolutionary medical operation. The technique Barnard employed had been initially developed by a group of American researchers in the 1950s. American surgeon Norman Shumway achieved the first successful heart transplant, in a dog, at Stanford University in California in 1958.

After Washkanskys surgery, he was given drugs to suppress his immune system and keep his body from rejecting the heart. These drugs also left him susceptible to sickness, however, and 18 days later he died from double pneumonia. Despite the setback, Washkanskys new heart had functioned normally until his death.

In the 1970s, the development of better anti-rejection drugs made transplantation more viable. Dr. Barnard continued to perform heart transplant operations, and by the late 1970s many of his patients were living up to five years with their new hearts. Successful heart transplant surgery continues to be performed today, but finding appropriate donors is extremely difficult.

Mechanical Circulatory Support And Devices

If youre unable to undergo a heart transplant or need additional support while on the heart transplant waiting list, a heart pump may be an option for you. These include mechanical circulatory support and artificial hearts. These devices might be implanted in those who are:

  • Awaiting transplant
  • Expected to regain full heart strength and function with treatment
  • Deemed ineligible to receive a transplant

Mechanical circulatory support enables patients with end-stage heart failure to live longer and feel better. These devices are often used as a bridge treatment leading to transplant.

Heterotopic Heart Transplantation: The Clinical Programme

Forty-nine consecutive heterotopic heart transplants were performed in Cape Town between 1974 and 1983, with moderately good results for that era.7 Three of the first five patients survived more than 10 years. During this time it became clear that if irreversible rejection and failure of the donor heart developed, excision and replacement of the donor heart was not only technically difficult, but associated with significant morbidity. At the re-transplant operation, it was preferable to replace the patients native heart by performing an orthotopic transplant, leaving the original heterotopic transplant in situ, even if it were no longer functioning. This prevented the necessity of dissecting the donor heart from the right lung, to which it might be tightly adherent.

Two 14-year-old boys, both of whom initially received heterotopic transplants, underwent a second heart transplant for graft atherosclerosis, and were therefore the first patients in the world to have two donor hearts in their chest at the same time. The first of these remains well, 29 and 26 years after the hetero- and orthotopic transplants, respectively. In the other, the second transplant also eventually failed and he underwent a third transplant, again in the orthotopic site, and thus became one of the few humans to have had four hearts in his lifetime.

An Experienced Heart Transplant Team

Our program is one of the most experienced in the world. We have performed more than 1,300 heart transplants including many dual-organ transplants, such as heart-lung and heart-kidney. Our surgeons have also pioneered methods to make donor organs more available and avoid post-transplant complications.

Doctor Who Pioneered Heart Transplant 50 Years Ago Helped Launch Okc Program

United States: First pig to human heart transplant, a game-changer for organ transplants | WION

Oklahoma City Fifty years ago, the first heart transplant revolutionized what was humanly possible, but the procedure was still in its infancy when it came to Oklahoma City almost two decades later.

Dr. Christiaan Barnard, who died in 2001, made history with the transplant in South Africa on Dec. 3, 1967. He also contributed to bringing the surgery to Oklahoma in the early 1980s.

The first patient to undergo a heart transplant died of pneumonia after 18 days. The second lived only 19 months. The problem wasn’t Barnard’s work as a surgeon, but the difficult balance between suppressing the immune system enough that it wouldn’t reject the organ, but not so much that the patient died of infections that normally wouldn’t have bothered them, said Dr. John Chaffin, chief of cardiovascular surgery at Integris Baptist Medical Center.

More than 15 years after the first transplant, surgeons still had to tinker with the available drugs in the hopes of giving patients a chance, Chaffin said. Insurers wouldn’t pay for a procedure they viewed as experimental, and the only patients who underwent the surgery were those who faced certain death if they didn’t, he said.

The whole concept of heart transplant in the ’80s was pretty rudimentary, he said.

Uncertain landscape

He was an incredible guy, just brilliant, Chaffin said.

Strong reputation

I always said that it took a great deal of courage on part to start a transplant program, he said. It was the frontier at that time.

The Development Of Heterotopic Heart Transplantation

In 1973, Barnard performed a heart transplant and the donor heart failed to function satisfactorily, so the patient died in the operating theatre. When Barnard came out to break the sad news, he was asked why he could not put the old heart back, as at least it had kept the patient alive. This struck Barnard as a distinct possibility. If the patients own heart had been left in place, and the transplant was inserted as an auxiliary pump, failure of the donor heart may not have caused the patients demise. Furthermore, during severe rejection episodes, which were common in those early days and a major cause of the poor results at the time, the native heart might be able to maintain the circulation while rejection was reversed by increased therapy.

Barnard set Jacques Losman, a junior surgeon on his team, to develop the surgical technique of heterotopic heart transplantation in the animal laboratory. The concept was for a second heart to be placed in the right chest and for the two hearts to function in parallel.6 Two techniques were developed in the laboratory, in one of which the donor heart assisted the left ventricle only and another in which biventricular assist was provided. Only two left ventricular assist procedures were performed in patients, the remaining operations involving biventricular support.

Why Choose Ucla Heart Transplant

Patients choose UCLA first and foremost because of our physicians skill and experience. We also offer several advantages not found elsewhere:

  • Exceptional outcomes: Our outcomes have remained consistently high since we began doing transplants in 1984. Highlights include:
  • Low rejection rates: Only 5 percent of our adult patients experience donor heart rejection, the lowest rate in the country. The national average is 25 percent.
  • High patient survival rates: Our graft and patient survival rates regularly rank higher than expected, according to the Scientific Registry of Transplant Recipients . These results are notable, considering that we routinely take on patient cases that are anything but routine.
  • Fewer heart biopsies: UCLA pioneered a blood test that can identify potential rejection early. The tests reliability means our patients do not need to undergo heart biopsies at the one-year mark following transplantation a welcome development for comfort and safety.
  • Highly skilled, multi-organ transplant expertise: Unlike many centers, we transplant all solid organs. Whether you need a single-organ transplant or experience multiple-organ failure, we have the expertise, talent and resources to provide top care. We also excel in lung transplant, as the busiest thoracic transplant center in the West and the second busiest in the country.

    Thomas Never Went To Medical School But He Had A Genius A Stunning Dexterity He Might Have Been A Great Surgeon Instead He Became A Legend

    In 1989, Washingtonian

    Say his name, and the busiest heart surgeons in the world will stop and talk for an hour. Of course they have time, they say, these men who count time in seconds, who race against the clock. This is about Vivien Thomas. For Vivien theyll make time.

    Dr. Denton Cooley has just come out of surgery, and he has 47 minutes between operations. No, you dont need an appointment, his secretary is saying. Dr. Cooleys right here. He wants to talk to you now.

    Cooley suddenly is on the line from his Texas Heart Institute in Houston. In a slow Texas drawl he says he just loves being bothered about Vivien. And then, in 47 minutesjust about the time it takes him to do a triple bypasshe tells you about the man who taught him that kind of speed.

    No, Vivien Thomas wasnt a doctor, says Cooley. He wasnt even a college graduate. He was just so smart, and so skilled, and so much his own man, that it didnt matter.

    And could he operate. Even if youd never seen surgery before, Cooley says, you could do it because Vivien made it look so simple.

    Together they devised an operation to save Blue Babies infants born with a heart defect that sends blood past their lungs and Cooley was there, as an intern, for the first one. He remembers the tension in the operating room that November morning in 1944 as Dr. Blalock rebuilt a little girls tiny, twisted heart.

    It was enough to make him want to head back to Nashville and take up his carpenters tools again.

    Daniel Hale Williams And The First Successful Heart Surgery

    A people who dont make provision for their own sick and suffering are not worthy of civilization.Daniel Hale Williams

    The son of a barber, Daniel Hale Williams founded the first black-owned hospital in America, and performed the world’s first successful heart surgery, in 1893. Williams was born in 1858 in Hollidaysburg, Pennsylvania, the fifth of seven children. After his father died, his mother, Sara Price Williams, moved the family several times. Young Daniel started as a shoemaker, but quickly knew he wanted more education. He completed secondary school in Wisconsin. At age 20, Williams became an apprentice to a former surgeon general for Wisconsin. Williams studied medicine at Chicago Medical College.

    After his internship, he went into private practice in an integrated neighborhood on Chicago’s south side. He soon began teaching anatomy at Chicago Medical College and served as surgeon to the City Railway Company. In 1889, the governor of Illinois appointed him to the state’s board of health.

    Determined that Chicago should have a hospital where both black and white doctors could study and where black nurses could receive training, Williams rallied for a hospital open to all races. After months of hard work, he opened Provident Hospital and Training School for Nurses on May 4, 1891, the country’s first interracial hospital and nursing school.

    Dr. Williams died in 1931. The Daniel Hale Williams Medical Reading Club in Washington, D.C., commemorates his achievements.

    Years Ago Stanford Heart Doctors Made History

    On Jan. 6, 1968, as Stanford surgeon Norman Shumway performed the first U.S. adult heart transplantation, the world held its breath.

    For 30 seconds on the afternoon of Jan. 6, 1968, in an operating room at Stanford Hospital, two human hearts lay very still in two separate basins near the unconscious body of a 54-year-old patient, and time froze.

    We both stood there and stared into this huge, empty cavity for a good half a minute, said Edward Stinson, MD, chief resident at the time. It was a magical moment. The young surgeon was assisting his mentor Norman Shumway, MD, PhD, chief surgeon, who had just removed Mike Kasperaks diseased heart in an effort to save the retired steelworkers life. It was the first attempted heart transplant in an adult in the United States.

    Do you think this is really legal? Stinson asked Shumway.

    I guess well see, Shumway said.

    One of the two hearts, diseased beyond repair, would never beat again. But the other, if transplanted into Kasperaks chest within the next hour or two, could possibly start up again and save his life. It was an outrageous act that was being followed with bated breath by the world as a frenzied press corps, camped out in the hallways of the hospitals basement, issued moment-by-moment reports.

    On that cold, bright winter day in 1968, the spell broke and the surgeons got back to work. There was no turning back.

    Bringing The Donor To Stanford

    That afternoon, Stinson was sent to pick up Virginia White at El Camino Hospital in an ambulance and deliver her, with her heart still beating, to Stanford Hospital at 3:30 p.m. Shumway received a neurologists confirmation of brain death in order to proceed, and the surgery began.

    Two surgical teams were set up in two adjoining rooms on the second floor of the east wing of the hospital. Stinson removed Whites heart in Room 12, then walked it over in a basin filled with cold saltwater to Room 13, where Shumway was waiting.

    Shumway and cardiologist Ed Harrison spoke to the media after the historic transplant surgery.Stanford Medical History Center

    Kasperak was connected to a heart-lung machine that kept his blood circulating to keep him alive while Shumway cut out his diseased heart.

    Whites heart, just a third the size of Kasperaks, which was swollen by disease, was then lifted out of its basin and placed inside the empty chest cavity. Shumway sutured Whites heart into Kasperaks chest, connecting the major heart vessels the vena cava, the aorta, the pulmonary artery and the left atrium

    In all, the surgery took about 3½ hours. Whites heart had been motionless for two hours. Now, there was nothing to do but wait and see if it would beat again.

    The excitement was palpable, Harrison said. Ten, 20 minutes passed. At 25 minutes, the new heart faintly pulsed and then grew stronger. We were all elated.
