Heart attack victims are walking around, without a pulse.
That is because they are being kept alive by a new artificial heart so small, so silent, that most people can not even tell they have one.
Ed Layton is happy just to be able to get his own mail.
For the last ten years, he walked nine miles a day delivering other peoples letters, until he had a massive heart attack that blew a hole in his heart.
Then an Ohio State surgeon gave him a second chance.
Now, Ed has a seven pound heart pump that does the work of his heart 24 hours a day.
The temporary, total artificial heart or TAHT, consists of two ventricles connected to the Pulmonary Artery and Aorta.
The pump is attached to batteries outside the body.
"It is an athlete, the heart, which has been damaged, so we rest it. It's like putting it on the couch, so it gets better," said Benjamin Sun, M.D. at Ohio State University.
Ed is able to do every day chores he used to take for granted.
The temporary pump is portable and allows heart patients to go home from the hospital while waiting on transplants.
