First Self-contained Heart Implanted
A patient on the brink of death has received the world's first self-contained artificial heart一a battery-
powered device about the size of a softball that runs without the need for wires,tubes or hoses sticking out of
the chest.
Two surgeons from the University of Louisville implanted the titanium and plastic pump during a
seven-hour operation at Jewish Hospital Monday.The hospital said the patient was"awake and responsive"
Tuesday and resting comfortably.It refused to release personal details.
The patient had been expected to die within a month without the operation,and doctors said they
expected the artificial heart to extend the person's life by only a month.But the device is considered a major
step toward improving the patient's quality of life.
The new pump,called AbioCor,is also a technological leap from the mechanical hearts used in the
1980s,which were attached by wires and tubes to bulky machinery outside the body. The most famous of
those,the Jarvic-7,used air as a pumping device and was attached to an apparatus about the size of a washing
machine.
"I think it's potentially a major step forward in the artificial heart development,"said Dr. David Faxon,
president of the American Heart Association.However,he said the dream of an implantable,permanent
artificial heart is not yet a reality:"This is obviously an experimental device whose long-term success has to
be demonstrated."Only about half of the 4,200 Americans on a waiting list for donor hearts received them
last year,and most of the rest died.
Some doctors ,including Robert Higgins, chairman of cardiology(心脏病学)at the Medical College of
Virginia in Richmond,said artificial hearts are unlikely to replace donor hearts.
"A donor heart in a good transplant can last 15 to 30 years,"he said."It's going to be hard to replace
that with a machine."
The AbioCor has a 2-pound pumping unit,and electronic controls that adjust the pumping speed based
on the body's needs.It is powered by a small battery pack worn outside the body that transmits current
through the skin.
There is no difference in structure between the self-contained heart and the mechanical heart.
A.Right
B.Wrong
C.Not mentioned
