Implanted pump helps heart-failure patient graduate from high school

Implanted pump helps heart-failure patient graduate from high schoolDoctors said 17-year-old Tovi Balliao was too sick to wait for a heart transplant. But now, a pump implanted in his heart has let him delay a transplant indefinitely. In February, Tovi TJ Balliao and his family received devastating news: The 17-year-old was suddenly in heart failure, experiencing life-threatening bouts of irregular heart rhythm.

He seemed normal, laughing with his siblings, but doctors told us, Hes like a switch. At any time, he can turn off, said TJs father, Marlon.

We were so overwhelmed, said his mother, Divinia.

The diagnosis, severe dilated cardiomyopathy, often strikes without warning or any apparent trigger. TJ needed a new heart, but he was too sick to wait for a heart transplant.

The wait time for a transplant was much longer than we could expect TJ to be stable, said David Rosenthal, MD, a cardiologist at Lucile Packard Childrens Hospital Stanford.

Thats why TJ immediately received a ventricular assist device, a pump surgically implanted in his heart to help it move blood through his body. At first, the Balliao family thought the pump would keep TJ alive only until a donor heart became available. But the VAD enabled him to recover so strongly that doctors gave him an unusual option: He could go home with his VAD and delay a transplant indefinitely.
Adding to a patients life span

For TJ, a high school senior, this meant the opportunity to graduate with his class. For his doctors, it represented a new avenue for treating children with heart failure. Although some adult heart-failure patients now live with VADs for months or years, children who get the pumps are usually transplanted as soon as possible. Rosenthal thinks TJs case could represent a change in thinking.

Its possible that using a VAD to intentionally delay a heart transplant could add to the patients total life span, said Rosenthal, a professor of pediatrics at the School of Medicine who directs the hospitals pediatric heart failure and transplantation program. Survival after transplant is not as long as the natural life span, especially for children.

The benefits of a VAD are many. It helps patients maintain strength while waiting for a new heart; otherwise, heart failure weakens the body, making recovery from eventual transplant more difficult. And when a child is stabilized with a VAD, the medical team can be more selective about choosing a donor heart that is an excellent match for the recipient. Plus, said Rosenthal, there is some likelihood that a small proportion of patients hearts will be able to recover and those children will avoid transplant completely.
Rosenthals forward-thinking approach to the devices continues a long tradition of leadership in VADs from his team at the hospitals Heart Center. In 2004, the Stanford Childrens Health team was the first in the western United States to use a VAD to help a child survive until he could undergo a transplant: The team employed an early version of the device, a Berlin Heart, to help the infant live through a 55-day wait for a new heart.

The Berlin Heart was large and cumbersome, requiring children to live in the hospital. In contrast, TJ has a portable VAD called a Heartware HVAD, with a messenger-bag-style battery pack he wears when hes not near an electrical outlet.

Its cool: It tells me when it needs me, TJ said. It beeps to remind me to change the battery every six to eight hours. He numbered the machines four batteries to ensure that hes always charging and using them in a strict rotation, one of many tips he received from Jenna Murray, RN, the hospitals VAD coordinator.
No longer confined to hospital

Hes very organized; he did that himself, Divinia, his mother, said. He also knows all his medications, and hes the one who fills up his pill box. Hes pretty responsible.

Although life with the VAD comes with restrictions no swimming, for instance its a huge improvement over the early days of TJs illness, when his failing heart confined him to the hospital.

I feel a lot better, he said. I can walk better, and that feels great.

TJ is pretty adaptable, said Rosenthal.

After the teens June graduation, the medical team and the Balliao family will assess the next steps. TJ has been accepted to San Jose State University to study civil engineering, so he may be sitting in introductory engineering classes next fall with his trusty Heartware battery pack at his side. Perhaps hell eventually receive a newer VAD that has an internal power source to free him from his 24-hour tether to a battery or wall outlet. Such devices, Rosenthal said, are not far off.

I like the idea of keeping that kind of option open for him, Rosenthal said. Our team is grateful to be on the forefront of expanding choices for kids with heart failure.
