FDA Approves Mechanical Cardiac Assist Device for Children With Heart Failure
SILVER SPRING, Md., Dec. 16, 2011 /PRNewswire-USNewswire/ -- The U.S. Food and Drug Administration today approved a medical device that supports the weakened heart of children with heart failure to help keep them alive until a donor for a heart transplant can be found.
The mechanical pulsatile cardiac assist device is called the EXCOR Pediatric System, made by a German company, Berlin Heart. The device comes in graduated sizes to fit children from newborns to teens.
"This is a step forward, it is the first FDA-approved pulsatile mechanical circulatory support device specifically designed for children," said Susan Cummins, M.D., M.P.H., chief pediatric medical officer in the FDA's Center for Devices and Radiological Health. "Previous adult heart assist devices were too large to be used in critically ill children to keep them alive while they wait to get a new heart."
The device consists of one or two external pneumatic (driven by air) blood pumps, multiple tubes to connect the blood pumps to heart chambers and the great arteries, and the driving unit.
Heart failure in children is much less common than in adults. Heart transplantation offers effective relief from symptoms. However, far fewer pediatric sized donor hearts are available for transplantation than for adults, limiting the use of heart transplantation in children and prolonging the waiting period until transplant can occur. In infants, the median waiting time for a donor heart is 119 days. Overall a reported 12-17 percent of children and 23 percent of infants die while on the wait list for a heart transplant.
In the primary U.S. study group of 48 patients, the use of the device was found to improve survival to transplant in patients when compared with the use of extracorporeal membrane oxygenation (ECMO) which is the current standar
