MIAMI -
D'Zhana Simmons says she felt like a "fake person" for 118 days when she had no heart beating in her chest.
"But I know that I really was here," the 14-year-old said, "and I did live without a heart."
As she was being released Wednesday from a Miami hospital, the shy
teen seemed in awe of what she's endured. Since July, she's had two
heart transplants and survived with artificial heart pumps — but no
heart — for four months between the transplants.
Last spring D'Zhana and her parents learned she had an enlarged
heart that was too weak to sufficiently pump blood. They traveled from
their home in
Clinton, S.C. to
Holtz Children's Hospital in Miami for a heart transplant.
But her new heart didn't work properly and could have ruptured so surgeons removed it two days later.
And they did something unusual, especially for a young patient: They
replaced the heart with a pair of artificial pumping devices that kept
blood flowing through her body until she could have a second transplant.
Dr. Peter Wearden, a cardiothoracic surgeon at
Children's Hospital of Pittsburgh who works with the kind of pumps used in this case, said what the Miami medical team managed to do "is a big deal."
"For (more than) 100 days, there was no heart in this girl's body? That is pretty amazing," Wearden said.
The pumps, ventricular assist devices, are typically used with a
heart still in place to help the chambers circulate blood. With
D'Zhana's heart removed, doctors at Holtz Children's Hospital crafted
substitute heart chambers using a fabric and connected these to the two
pumps.
Although artificial hearts have been approved for adults, none has
been federally approved for use in children. In general, there are
fewer options for pediatric patients. That's because it's rarer for
them to have these life-threatening conditions, so companies don't
invest as much into technology that could help them, said
Dr. Marco Ricci, director of pediatric cardiac surgery at the
University of Miami.
He said this case demonstrates that doctors now have one more option.
"In the past, this situation could have been lethal," Ricci said.
And it nearly was. During the almost four months between her two
transplants, D'Zhana wasn't able to breathe on her own half the time.
She also had kidney and liver failure and gastrointestinal bleeding.
Taking a short stroll — when she felt up for it — required the help
of four people, at least one of whom would steer the photocopier-sized
machine that was the external part of the pumping devices.
When D'Zhana was stable enough for another operation, doctors did the second transplant on Oct. 29.
"I truly believe it's a miracle," said her mother,
Twolla Anderson.
D'Zhana said now she's grateful for small things: She'll see her five siblings soon, and she can spend time outdoors.
"I'm glad I can walk without the machine," she said, her turquoise
princess top covering most of the scars on her chest. After thanking
the surgeons for helping her, D'Zhana began weeping.
Doctors say she'll be able to do most things that teens do, like
attending school and going out with friends. She will be on lifelong
medication to keep her body from rejecting the donated heart, and
there's a 50-50 chance she'll need another transplant before she turns
30.
For now, though, D'Zhana is looking forward to celebrating another
milestone. On Saturday, she turns 15 and plans to spend the day riding
in a boat off Miami's coast.
