Two of the first six
AbioCor artificial heart patients -- all of whom were dying of
heart failure and too sick to qualify for human heart transplants
-- are reported making dramatic progress several months after
receiving their implants.
Tom Christerson, the
second man to receive a self-contained artificial heart, is steadily
improving and in a few weeks will set the new record as longest
to survive with an AbioCor heart.
Christerson,
70, who received the AbioCor heart at Jewish Hospital in Louisville
on Sept. 13, is still breathing by way of a hole cut in his throat
because saliva was seeping into his lungs when he swallowed.
"He's
really improved a lot in the couple weeks, he's really doing well,"
son Ken Christerson said.
James Quinn,
51, the fifth AbioCor recipient, was released Jan. 14 from Hahnemann
University Hospital, exactly 70 days after receiving his artificial
heart.
Quinn suffered
a mild stroke on the morning of Dec. 31, and now uses a walker
for balance and has slightly slurred speech, impaired vision and
a weakened left side. However, he was strong enough to be discharged.
"We
are very happy for James. We hope he can begin to truly enjoy
his family in a non-hospital setting," Dr. Louis Samuels,
surgical director of the cardiac transplant team, said in a statement.
Quinn is staying
in a
hotel about three blocks from the hospital, with caregivers in
an adjoining room.
The first
AbioCor recipient, Robert Tools, of Franklin, Ky., lived nearly
five months with the plastic and titanium device in his chest
before dying on Nov. 30.
Two of the
other six patients have died, one like Tools of organ failure
and one of massive bleeding during surgery.
Abiomed Inc.'s
plastic-and-titanium device has an internal battery and controller
that are implanted with the heart and an external battery that
passes electricity through the skin. Unlike earlier artificial
hearts, the AbioCor heart has no wires or tubes that stick out
of the chest.
