Reference excerpt

Jack Greene Copeland (born 1942) is an American cardiothoracic surgeon, who has established procedures in heart transplantation including repeat heart transplantation, the implantation of total artificial hearts (TAH) to bridge the time to heart transplant, innovations in left ventricular assist devices (LVAD) and the technique of "piggybacking" a second heart (heterotopic heart transplant) in a person, while leaving them the original. In 1985, he performed the first successful implant of the Jarvik 7 artificial heart for the purpose of gaining time until a suitable heart donor could be found. The 25-year-old recipient received the heart transplant within two weeks of the implant and survived more than five years. Copeland co-founded SynCardia Systems and after being head of the cardiothoracic surgery programme at the University of Arizona Medical Center (UAMC) in Tucson for over thirty years, he moved to the University of California, San Diego in 2010. He was one of the first presidents of the International Society of Heart and Lung Transplantation (ISHLT), a society he helped co-found and who awarded him its Past Pioneer Award in 2013.

Early life and education

Jack Copeland was born in 1942 in Roanoke, Virginia and is the son of a chemical engineer. He entered Stanford University as a biology major in 1960, and subsequently earned a medical degree there nine years later. His interest in transplant surgery stemmed from his medical student days at Stanford, when he took up a job assisting in heart transplants in animals.

Early career Copeland completed his internship and residency at the University Hospital of San Diego County, then assisted at the National Heart, Lung, and Blood Institute at Bethesda, Maryland, where he reported on extended heart preservation outside the body, before returning to Stanford. At Stanford, he became chief resident of cardiac surgery and in 1977 reported the first successful repeat-heart transplant in a human. He was inspired predominantly by heart surgeons Norman Shumway and Edward Stinson and he learned the technique of endomyocardial biopsy and interpretation of organ rejection grading from cardiothoracic surgeon Philip Caves and pathologist Margaret Billingham. The University of Arizona hired Copeland in 1977 and two years later he led the first heart transplant in Arizona. In 1982 Copeland stated that heart transplants were "no longer consider[ed] … an experiment here. It has become a routine and predictable procedure". At Arizona, he was one of the first surgeons in the country to try the technique of "piggybacking" a second heart in a person, while leaving them the original, a procedure first performed by South African heart surgeon Christiaan Barnard. By 1985, at the age 43, when he was head of the Cardiovascular and Thoracic Surgery Section at the University of Arizona College of Medicine in Tucson, his team had performed over sixty such transplants. In addition, in 1985, he performed Arizona's first combined heart-lung transplant.

The first bridge-to-transplant with a total artificial heart

In 1985, Copeland and Mark Levinson with help from biomedical engineer Richard Smith, performed the first successful implant of the Jarvik 7 total artificial heart, the early version of the SynCardia TAH, in 25-year-old grocery store clerk Michael Drummond who was suffering with severe heart failure due to cardiomyopathy and was awaiting a heart transplant. It was the first time this procedure was performed successfully as a temporary measure to buy time until a matching donor heart could be found. The previous TAH implants were temporary by Cooley (1969 and 1981) and Copeland (1985) had failed to result in survival for more than days and several were "permanent" TAH implants by William DeVries (Barney Clark in December 1982) that resulted in short term survival. Prior to the first success, in March 1985, Copeland and his team had emergently implanted the unapproved Phoenix total artificial heart in a critically ill young man. The FDA policy of making exceptions for unapproved devices use in true emergencies followed this case. The Michael Drummond case followed in August 1985. Worsening of Drummond's condition created a desperation for action and the decision to use a TAH. It allowed time to find a matching donor heart. He survived more than five years, having received his heart transplant within two weeks of the implant. His cause of death was lymphoma. Copeland, along with Don B. Olsen, was instrumental in forming CardioWest Technologies and continuing the research and development of TAH technology and its role in bridging-to-heart transplant. Following FDA approval to trial the CardioWest TAH, he published his ten-year trial (1993–2002), assessing the performance of the TAH in just less than 100 people with class IV biventricular heart failure and at risk of imminent death. All included in the trial were eligible for transplant but were waiting for donors. The trial demonstrated better clinical outcomes when the TAH was used to bridge-to-transplant. In 2001, he co-founded SynCardia Systems which acquired CardioWest Technologies. In 2004, the SynCardia heart was granted FDA approval for use as a bridge-to-transplant. It is the only TAH to obtain FDA approval and be commercially available.

Other cardiac surgery In 2000, he performed America's first implant of a paediatric ventricular assist device. In 2010, he and his team also reported their results of using LVADs in infants and children with severe heart failure from dilated cardiomyopathy. Other procedures he has led include heart valve surgery, cardiac bypass surgery in adults and the repair of congenital heart defects in infants.

Later career

He resigned from the University of Arizona in 2010 after heading its Cardiovascular and Thoracic Surgery Section for over thirty years and subsequently moved to San Diego, where his wife was completing her general surgery training. Here, he joined the faculty at the new Sulpizio Family Cardiovascular Center at the University of California, San Diego.

First FDA approved total artificial heart On 7 January 2011, during a four-hour operation, Copeland was part of the team that implanted, as a bridge-to-transplant, the world's only FDA-approved total artificial heart (TAH) for temporary use.

Worked examples

Example 1 — a first encounter with Jack Copeland (surgeon)

Start with the simplest possible case. Write down what Jack Copeland (surgeon) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jack Copeland (surgeon) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jack Copeland (surgeon) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jack Copeland (surgeon)

In research
Jack Copeland (surgeon) appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Jack Copeland (surgeon) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Jack Copeland (surgeon) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1942 births, American transplant surgeons, History of heart surgery, so understanding it makes those chapters shorter.
In everyday life
Look for Jack Copeland (surgeon) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
