Pig hearts for people – level 1

02-03-2023 07:00

David Bennett comes from the United States. He is 57 years old. His heart is very sick. His only chance is a transplant of a pig’s heart.

The surgery goes well. Doctors are happy that the man survives. But everything changes quickly. The new heart is not working well. The man dies. Doctors find out that there is a pig virus in the heart. Doctors do tests before the surgery. The tests don’t find the virus. Now, more sensitive tests exist.

Doctors must also learn more about immune suppressing drugs. These drugs help the body accept the new organ. Experts test this on monkeys. Monkeys get pig heart transplants.

Now, there is no plan for another such surgery.

Difficult words: transplant (an organ which doctors take from one body and put it into another body), survive (to still live after an event or accident), immune suppressing drugs (drugs which cause a body doesn’t react strongly to a transplant).

You can watch the original video in the Level 3 section.

What is the virus that killed David Bennett's new heart?
