Heart transplant centre
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the person's own body, to replace the recipient's damaged or absent organ. Organs and/or tissues that are transplanted within the same person's body are called autografts.
Transplants that are recently performed between two subjects of the same species are called allografts. Allografts can either be from a living or cadaveric source. Transplantation of organs has been considered one of the significant advances that have occurred in medicine offering a healthy life back to numerous people all over the world.
Heart transplantation has emerged as a viable therapeutic strategy for select patients with end-stage heart disease, offering extended survival and improved quality of life. The first transplantation in MICC was in November 2015 and it’s the first heart transplantation in North Kerala. Transplant Services in MICC and has been implementing the policies of the Kerala Network for Organ Sharing . The institution has led the state in deceased organ procurement and has been involved in the training of other teams from the state.
The first heart transplant in human beings was done in South Africa in 1967 by Dr. Christian Barnard; the patient lived for 18 days. Approximately 4000 heart transplantation procedures are performed annually worldwide. Long-term outcomes after transplantation have improved with the advances made in transplant candidate selection, surgical techniques, immunosuppressive regimens, and postoperative care. Cardiac transplant patients are treated by an integrated multi disciplinary team comprising off cardiothoracic surgeons, Cardiologists, Critical Care Specialists, and other Supporting services
- Ischemic heart disease
- Hypertrophic heart disease.
- Severe decompensated inoperable valvular heart disease.
- Congenital heart disease
- Any other cardiac abnormalities that severely limit normal function and/or have a mortality risk of greater than 50 percent at two years.
- Assist Device dependent patients who meet criteria for transplantation.
- Age younger than 60 years (Will consider 60 to 70 years old on case-by-case basis).
- Life-threatening heart rhythm disorders that fail treatment.
- Chest pain refractory to maximum medical and surgical therapy.
A dedicated team is available to coordinate the transplant work up process. Depending on medical history, investigations and tests transplant work up will be carried out. Most evaluations will include:
- Blood testing
- Heart studies, which may include any or all of the following:
- Echocardiogram (ECHO)
- Electrocardiogram (ECG)
- Holter monitoring
- Cardiac catheterization.
- Pulmonary function tests
- Urinary system evaluation
- Abdominal ultrasound
- Chest x-ray
- Vascular Doppler studies
- Dental exam, including x-ray
- Complete physical exam
You may be discharged from the hospital before all the results are available, and some of the testing may be done as an outpatient. After the workup process is complete, case will be discussed and decision to list in the KNOS (Kerala network for organ sharing) will be taken.
Heart transplantation consists of three operations.
The first operation is harvesting the heart from the donor. The donor is usually an unfortunate person who has suffered irreversible brain injury called "brain death". Very often these are patients who have had major trauma to the head, for example, in an automobile accident. The victim's organs, other than the brain, are working well with the help of medications and other "life support" that may include a respirator or other devices. A team of physicians, nurses, and technicians goes to the hospital of the donor to remove donated organs once brain death of the donor has been determined. The removed organs are transported on ice to keep them alive until they can be implanted. For the heart, this is optimally less than four hours.
The second operation is removing the recipient's damaged heart. Removing the damaged heart may be very easy or very difficult, depending on whether the recipient has had previous heart surgery (as is often the case). If there has been previous surgery, cutting through the scar tissue may prolong and complicate removal of the heart.
The third operation is the implantation of the donor heart. This operation basically involves the creation of only five lines of stitches, or "anastomoses". These suture lines connect the large blood vessels entering and leaving the heart. Remarkably, if there are no complications, most patients who have had a heart transplant are home about one week after the surgery.
Complications of a heart transplant
Our immune system attacks transplanted organs. This is what happens when organs are rejected; they are recognized as foreign by the body. Rejection is controlled with powerful "immunosuppressive" medications. If there are not enough immunosuppressants the organ can reject acutely. Even when it seems that there is no active rejection, there may be more subtle chronic rejection that consists of a growth of tissue, something like scar tissue, which causes blockage of the blood vessels of the heart. The blockage of the vessels is the process that ultimately causes the transplanted heart to fail. It is this chronic rejection that is the major limiting factor for the long-term success of heart transplantation.. While immune suppression blocks rejection, because it suppresses the immune system, transplant patients are more susceptible to infection and cancers of various types.
