FLORIDA — BACKGROUND: The human heart works like a pump, circulating blood to all the body’s cells. The right side takes blood from the body and pumps it into the lungs, while the left side takes blood from the lungs and pumps it out to the body. An average heart beats about 100,000 times a day. When the heart starts to fail, it may struggle to pump blood, and muscle function can deteriorate. Patients with a failing heart may need a heart transplant. There are many devices that can support and keep adults healthy until they receive a donor heart transplant. However, that’s not the case for kids. As many as 20 percent of children waiting for a transplant die before an organ is available.
