A heart transplant, or a cardiac transplant, is a surgical transplant procedure performed on patients with end-stage heart failure or severe coronary artery disease when other medical or surgical treatments have failed. As of 2016, the most common procedure is to take a functioning heart (with or without transplantation of a lung or lungs; a cadaveric donor cardiectomy) from a recently deceased organ donor (the cadaveric allograft), and implant it into the patient. The patient's own heart is either removed (the cardiectomy for the recipient) and replaced with the donor heart (orthotopic procedure) or, less commonly, the recipient's diseased heart is left in place to support the donor heart (heterotopic procedure). Approximately 3500 heart transplants are performed every year in the world, more than half of which occur in the US.[1] Post-operation survival periods average 15 years.[2] Heart transplantation is not considered to be a cure for heart disease, but a life-saving treatment intended to improve the quality of life for recipients.[3]


One of the first mentions of the possibility of heart transplantation was by American medical researcher Simon Flexner, who declared in a reading of his paper on “Tendencies in Pathology” in the University of Chicago in 1907 that it would be possible in the then-future for diseased human organs substitution for healthy ones by surgery — including arteries, stomach, kidneys and heart.[4]

Norman Shumway is widely regarded as the father of heart transplantation although the world's first adult human heart transplant was performed by a South African cardiac surgeon, Christiaan Barnard, utilizing the techniques developed and perfected by Shumway and Richard Lower.[5] Barnard performed the first transplant on Louis Washkansky on December 3, 1967, at the Groote Schuur Hospital in Cape Town, South Africa.[5][6] Adrian Kantrowitz performed the world's first pediatric heart transplant on December 6, 1967, at Maimonides Hospital in Brooklyn, New York, barely three days after Christiaan Barnard's pioneering operation.[5] Since the 19-day-old infant died little more than six hours after receiving the heart, this operation was considered a failure.[7]Norman Shumway performed the first adult heart transplant in the United States on January 6, 1968, at the Stanford University Hospital.[5]

Worldwide, about 3,500 heart transplants are performed annually. The vast majority of these are performed in the United States (2,000–2,300 annually).[1] Cedars-Sinai Medical Center in Los Angeles, California, currently is the largest heart transplant center in the world, having performed 132 adult transplants in 2015[8] alone. About 800,000 people have NYHA Class IV heart failure symptoms indicating advanced heart failure.[9] The great disparity between the number of patients needing transplants and the number of procedures being performed spurred research into the transplantation of non-human hearts into humans after 1993. Xenografts from other species and man-made artificial hearts are two less successful alternatives to allografts.[2]

Most published surgical methods of HT necessarily divide the Vagus nerve and thus amputate parasympathetic control of the myocardium.[10]


Some patients are less suitable for a heart transplant, especially if they suffer from other circulatory conditions related to their heart condition. The following conditions in a patient increase the chances of complications;

Relative contraindications:


Patients who are in need of a heart transplant but do not qualify, may be candidates for an artificial heart [1] or a left ventricular assist device i.e. LVAD.


Post-operative complications include infection, sepsis, organ rejection, as well as the side-effects of the immunosuppressive medication. Since the transplanted heart originates from another organism, the recipient's immune system typically attempts to reject it. The risk of rejection never fully goes away, and the patient will be on immunosuppressive drugs for the rest of his or her life, but these may cause unwanted side effects, such as increased likelihood of infections or development of certain cancers. Recipients can acquire kidney disease from a heart transplant due to side effects of immunosuppressant medications. Many recent advances in reducing complications due to tissue rejection stem from mouse heart transplant procedures.[12] Surgery death rate is 5-10% in 2011.[13]


The prognosis for heart transplant patients following the orthotopic procedure has increased over the past 20 years, and as of June 5, 2009, the survival rates were:[14]

In a study spanning 1999 to 2007, conducted on behalf of the U.S. federal government by Dr. Eric Weiss of the Johns Hopkins University School of Medicine, it was discovered that, compared to men receiving male hearts, "men receiving female hearts had a 15% increase in the risk of adjusted cumulative mortality" over five years. No significant differences were noted with females receiving hearts from male or female donors.[15]

Famous recipients

Other notable recipients

At the time of his death on August 10, 2009, Tony Huesman was the world's longest living heart transplant recipient, having survived for 30 years, 11 months and 10 days, before dying of cancer.[18] Huesman received a heart in 1978 at the age of 20 after viral pneumonia severely weakened his heart.[19] The operation was performed at Stanford University under Dr. Norman Shumway.[20]

As of February 2016, the record holder for longest living heart recipient was Englishman John McCafferty. He received his heart on 20 October 1982.[18] He died aged 73 on 9 February 2016, 33 years after his operation. The operation was performed at Harefield Hospital in Middlesex under Sir Magdi Yacoub.[21]

Former Vice President of the United States Dick Cheney received a heart transplant on March 24, 2012.[22] Because he was 71 years old at the time of the surgery, it sparked discussions about the upper age of transplant patients.[23]
