What is a Heart Transplant and How is it Done?

A heart transplant is a surgical procedure that involves replacing a diseased or damaged heart with a healthy heart from a donor. This procedure is typically reserved for patients with end-stage heart failure or other serious heart conditions that cannot be treated with medication or other less invasive procedures.

The first successful heart transplant was performed in 1967 by Dr. Christiaan Barnard in South Africa. Since then, advances in surgical techniques, immunosuppressive medications, and organ preservation have made heart transplantation a viable treatment option for many patients.

The heart transplant process involves several steps, including patient evaluation, donor selection, surgery, and post-operative care. In this article, we will explore each of these steps in more detail.

Patient Evaluation

Before a patient can be considered for a heart transplant, they must undergo a thorough evaluation to determine if they are a suitable candidate. This evaluation typically involves a series of tests and assessments, including:

– Medical history: The patient’s medical history will be reviewed to determine if they have any underlying health conditions that could affect the success of the transplant.

– Physical exam: A physical exam will be performed to assess the patient’s overall health and to look for signs of heart failure, such as swelling in the legs or shortness of breath.

– Diagnostic tests: A variety of diagnostic tests may be performed, including blood tests, electrocardiograms (ECGs), echocardiograms, and cardiac catheterization. These tests can help to determine the extent of the patient’s heart disease and whether a transplant is the best treatment option.

– Psychological evaluation: A psychological evaluation may be performed to assess the patient’s mental health and to ensure that they are emotionally prepared for the transplant process.

Donor Selection

Once a patient has been deemed a suitable candidate for a heart transplant, they will be placed on a waiting list for a donor heart. Donor hearts are typically obtained from individuals who have died and have agreed to donate their organs.

The process of donor selection involves several steps, including:

– Donor identification: Potential donors are identified through a network of organ procurement organizations (OPOs) that work with hospitals and medical centers across the country.

– Donor evaluation: Donors undergo a thorough evaluation to determine if their heart is suitable for transplantation. This evaluation typically involves a medical history review, physical exam, and diagnostic tests.

– Matching: Once a suitable donor heart has been identified, it must be matched to a suitable recipient based on factors such as blood type, body size, and medical urgency.


The heart transplant surgery itself typically takes several hours and involves several steps, including:

– Anesthesia: The patient will be given general anesthesia to ensure that they are unconscious and pain-free during the surgery.

– Incision: The surgeon will make an incision in the chest to access the heart.

– Removal of the diseased heart: The surgeon will remove the patient’s diseased heart, leaving the pulmonary veins and arteries intact.

– Implantation of the donor heart: The donor heart will be implanted into the patient’s chest and connected to the pulmonary veins and arteries.

– Closing the incision: The surgeon will close the incision with sutures or staples.

Post-Operative Care

After the surgery, the patient will be closely monitored in the intensive care unit (ICU) for several days. During this time, they will receive medications to prevent rejection of the donor heart and to manage pain and other symptoms.

Once the patient is stable, they will be transferred to a regular hospital room for further recovery. They will continue to receive medications to prevent rejection and will undergo regular monitoring to ensure that the donor heart is functioning properly.

In addition to medical care, patients who undergo heart transplant surgery will also need to make significant lifestyle changes to ensure the long-term success of the transplant. This may include following a healthy diet, getting regular exercise, and avoiding smoking and alcohol.


Heart transplant surgery is a complex and challenging procedure that requires careful patient evaluation, donor selection, and post-operative care. While it is not a cure for heart disease, it can provide a new lease on life for patients with end-stage heart failure or other serious heart conditions. With advances in surgical techniques and medical care, heart transplantation has become a viable treatment option for many patients, offering hope for a brighter future.
