A first-of-its-kind device was used recently at the Westchester Medical Center, and experts say it's a game-changer for heart transplants.

The Westchester Medical Center is the first hospital in the state to perform a heart transplant with this new technology called "Heart in a Box."

“Heart in a Box” keeps the heart beating during transport by pumping warm blood into it.

Typically, the heart is just stored in ice and can only last a few hours - and the heart can only be used for a transplant if it was beating when the donor passed away.

This means that the donor had to be brain dead.

The “Heart in a Box” can restart a heart and keep a heart alive for several hours.

It’s in clinical trials right now and was just used to transport a heart for Peter Myer.

He’s from Albany and had his transplant a few weeks ago.

He says he's happy and relieved to be alive and healthier today.

“I am very, very grateful because I have a family, I have grandchildren...you know, I have a lot of reasons to live," he says.
