Why is the heart and kidney the most common transplants?

Answer 1

There are two kidneys, but only one heart available for transplants taken from a single donor. Therefore, two patients could receive one kidney each, but only one patient could receive a heart.

Answer 2

because these two organs are most important for human body so scientists first dedicated all the research for these two vital organs and and as they are done successfully, scientists have moved their research on other organs too so research is still going on for the other organ transplant

Answer 3

Heart and kidneys are the most common transplants because of the type of work they do and the diseases which affect them. The most common disease that affect both is Diabetes. Diabetes decreases blood circulation causing a lack of blood flow to the heart's own circulatory system and eventually death of the muscle cells due to a lack of oxygen and nutrients. The kidney filters out body waste to create urine. Diabetes causes an increase urine flow without adequete filtering, wearing out the kidney before its normal lifetime.

Answer 4

Because the risks involved in a heart transplant (i.e the risk of dying) is quite high. A lot of heart transplants are done, but not many survive. Hence finding people with heart transplants is not common, but the operation is more common than you'd think.

Answer 5

Primary because the supply of donor livers and kidneys is higher than say, donor hearts.

For example, livers can be used from non-heartbeating donors, and can also be cut-down for use when the intended recipient is much smaller than the donor. They can also be split between two recipients. Living-donation can also be used under certain circumstances - e.g if the recipient is a child or small adult ( due to size constraints on how much liver it is safe to remove from the living donor ).

For kidneys, there is a good supply of living donors (since the vast majority of people have two healthy kidneys and can donate one without huge risk to their own health). Non-heartbeating donor kidneys can also be used for transplantation.

The demand for donor hearts is there, however the supply is not; hearts cannot be used from non-heartbeating donors (e.g it's not at all safe to transplant the heart of someone who has died from a heart-attack), cannot be resized, and cannot be donated by living people. The time allowed between retrival and transplant is also lower than livers or kidneys; hearts degrade quicker.

Most other forms of transplant have less demand (i.e fewer patients in need of them) - e.g small intestine and pancreas. For transplants which are not commonly performed, there is normally a decent supply of suitable organs.
