Introduction
Heart transplantation for infants and toddlers is becoming a widely accepted treatment option. Congenital abnormalities remain the leading cause of cardiac transplantation in babies. Congenital cardiomyopathy occurs in about one out of every 10,000 live births. Cardiomyopathy is the most common reason for older children to get heart transplants the number of children who experience deteriorating cardiac function after palliative surgery for congenital heart disease is growing.
What Is a Pediatric Heart Transplant?
A heart transplant is a surgical procedure in which doctors remove a sick person's heart and replace it with an undamaged donor heart. Transplants are performed when a child's heart fails and cannot survive without a new one. Doctors sometimes refer to this as heart failure or end-stage pediatric heart disease. They usually start by treating heart failure with medications, surgery, or other procedures. If those do not work, a youngster may require a heart transplant. Transplanted hearts are from organ donors who agreed to give away their organs after death. One would want to give their organs because they want to help someone who is ill. Many children who receive heart transplants go on to enjoy normal, healthy lives after recovering from surgery.
What Happens Before Heart Transplantation?
If a child requires a heart transplant, the physician will direct them to a transplant clinic. There, they will meet the members of the transplant team, which typically includes:
-
Surgeons and transplant cardiologists who are specialists in heart transplantation.
-
A transplant.
-
Nurse practitioner.
-
Dietitians and psychologists.
-
Social workers.
The healthcare team will begin a transplant evaluation to ensure that a transplant is the best choice for a kid. This will include:
-
Blood Tests: To identify blood type, check for infectious agents, and ensure that additional organs (such as the kidneys and liver) function properly.
-
An Echocardiogram: An ultrasonography that provides an image of the heart and indicates how well it functions. An electrocardiogram (ECG or EKG) is a test that captures the heart's electrical activity and can help discover any abnormalities with its rhythm or damage to the heart muscle itself.
-
Cardiac Catheterization: Cardiac catheterization allows doctors to see the heart and its chambers while the patient is asleep under anesthetic. The transplant evaluation enables the team to learn much about kids. However, it is also an opportunity for a child to learn what will happen before, during, and following the transplant. The transplant team is available to provide information and support. If one needs help understanding something, be sure to ask them. If the transplant team determines that the surgery could benefit the kid, the next step is to place the child's name on the organ-sharing transplant list. It may take many months to a year to find a compatible heart. The need for new hearts significantly outnumbers the number donated, so this could take a long time.
One will maintain close contact with the doctors and the rest of the healthcare team. Make sure to know how to contact them at all times. When a heart is accessible, one must act immediately. Pack a bag and be prepared to go to the transplant hospital anytime. Maintain the child's health while waiting for a transplant. In this manner, kids will be prepared for transplant surgery when the time comes. Help the child to:
-
Eat nutritious foods.
-
Take all medications as prescribed.
-
Attend all medical appointments.
-
If the child's condition changes or plans to go more than two hours away, notify the transplant team straight away.
What Happens During Heart Transplant Surgery?
-
The transplant team will get the child ready for surgery. Doctors may do several tests to ensure that the replacement heart is a good fit. The child will then be taken to an operation room.
-
In the operating room, kids will be given anesthesia to help them sleep through the procedure. The surgeon makes a cut in the chest to extract the diseased heart. The replacement heart is implanted in the chest, and the surgeon links its blood veins to those in the child's body.
-
Most heart transplant operations take four to six hours. Someone from the transplant team will keep the patient’s family informed on the progress of the surgery.
What Happens Following Heart Transplant Surgery?
-
Following heart transplant surgery, the kid will be in the cardiac intensive care unit (CICU). One can pay brief visits to children there. The child will receive pain medication. One will remain unconscious on the ventilator with a breathing tube in place until the physicians confirm that the replacement heart is functioning properly. It may take many days.
-
The child's condition determines how long they will be in the cardiac intensive care unit. Typically, the duration is seven to ten days. When ready, the child will be moved to the general cardiac floor. The transplant team will continue to care for and monitor the child.
-
Most children spend two to four weeks in the hospital following surgery. Children and their families learn how to care for their new hearts during this time. Ensure that the child understands the doctor's instructions because the child must follow them closely.
-
The child will return to the cardiology clinic several times in the weeks following discharge to ensure everything is in order. Typically, the child will have blood work done and testing, including an echocardiography and EKG. These visits will become less frequent with time.
What Can Parents Do to Help?
-
Children who have had a heart transplant can enjoy normal, healthy lives when they recover from surgery. Around three months following the transplant, they can return to school and can eventually participate in sports and other activities.
-
It is critical to keep the new heart healthy. Help the child take all medications as prescribed and not miss any doses.
-
Bring the child to all transplant clinic appointments as scheduled.
-
Talk to the transplant staff in case of any concerns.
What Are the Outcomes?
Pediatric heart transplant outcomes continue to improve as experience accumulates over time. The median survival time is 19.7 years for infants, 16.8 years for children ages one to five years, 14.5 years for children ages six to ten years, and 12.4 years for children 11 to 17 years of age at the time of transplantation. The largest death rate continues during the first year post-transplant. When accounting for conditional survival during the first year, the median survivals climb to 20.6 years for children ages one to five, 16.7 for children ages six to ten, and 16.1 years for children 11 to 17. The decreasing median survival in older age groups is most likely multifactorial and related to several factors, including infants' relatively immature immune systems and lack of preformed antibodies, sensitization in older children as a result of surgical repair, and palliation for cardiac heart disease, and risk-taking behaviors such as medication noncompliance.
Conclusion
Pediatric heart transplantation has become the standard of therapy for end-stage cardiac disease in children all across the world. The number of transplants has increased considerably since the initial transplant, and outcomes have continuously improved over the previous two decades as knowledge has advanced, improving the clinical course and outcomes of these patients. Short-term outcomes in the most recent era have been great, prompting a renewed emphasis on medium- and long-term outcomes.
