Stan and his brother Dominique were both diagnosed with the same condition. While Dominique got a donor in a couple of a weeks, Stan had to wait for a year before he received a full heart transplant. 

Until then, he carried an 'artificial heart' in a backpack which helped him pump blood around his body.

This artificial heart device is called Syncardia. Larkin carried this 6 kg device around 24/7 for 16 months before he received the transplant.

When asked about the transplant, the surgeon Jonathan Haft said to Science Daily-

"They were both very, very ill when we first met them in our intensive care units. We wanted to get them heart transplants, but we didn't think we had enough time. There's just something about their unique anatomic situation where other technology wasn't going to work."

The good news is that Stan Larkin has now fully recovered from the heart transplant surgery. Recalling all the struggle, he described his journey as an 'emotional roller-coaster' and shared it with the media with an aim to raise awareness about heart failures and the need for heart donors.
