Surgeons at the Milton S. Hershey Medical Center in Pennsylvania
report they have successfully implanted the Arrow LionHeart
left ventricular assist system [LVAS] for the first time in the
United States in a patient with end-stage heart failure.
The totally implanted system -- powered by battery that is recharged
by drawing energy across intact skin from an external battery pack
-- is capable of taking over the entire work load of the left ventricle.
It was approved for clinical testing in the United States by the
Food and Drug Administration less than one month ago.
Dr. Walter Pae, Jr. director of transplantation at Milton S.
Hershey, said the surgery lasted five hours. He said the patient
is in critical condition and recovering as expected.
Pae led the surgical team that performed the first implant of
the LVAS at the German Heart Center in Bad Oeynhausen, Germany
on a 67-year-old male. He said the patient is at home and doing
well.
The device, which utilizes technology developed at Penn State
during a period of more than 20 years, is intended as final therapy
for patients with end-stage heart failure who are not candidates
for heart transplantation. Pae said such patients have a low probability
of surviving six months.
"The Arrow LionHeart provides therapy for critically ill
patients considered ineligible for heart transplantation because
of age or other significant medical problems such as diabetes,"
said Pae. "I expect this will help thousands of people around
the world."
