In a heartwarming video that has gone viral, the relief Trevor Sullivan feels when he wakes up to take his first breath with a new heart is palpable.

The 15-year old cries and tells his dad how good he feels in the moments after his successful heart transplant on Nov. 13 at C.S. Mott Children’s Hospital in Ann Arbor. His dad Philip Sullivan recorded the video and posted it Tuesday, Jan. 19 on his Facebook page and shared it with organ donation agency Gift of Life Michigan.

WWJ’s Sandra McNeill reported that on Super Bowl Sunday last year Southfield resident Trevor Sullivan was treated for heart failure after shoveling snow. They found he had a heart defect and a transplant was the only hope to bring him back to good health.

“I’m so happy. I’ve been waiting for so long. I can breathe again and talk,” said Trevor Sullivan laying on a hospital bed hooked up to monitors with a large bandage on his chest.

“How do you feel?” asked his dad from behind the camera.

“I feel amazing,” replied Trevor.

Choking up, Philip repeated his son’s stunning answer, “Amazing?”

McNeill talked to Philip Sullivan, who described the video as Trevor’s reaction to his new heart and breathing without a tube. “Because the heart was so heavy it weighed really heavy on the lungs so it was hard for him to be able to breathe and hard for him to walk around so it pretty much describes how he feels he can actually breathe again.”

Philip says his son is still recovering and has developed issues with his blood sugar. They hope he can be back to school at Birmingham Groves High by March.
