First Self-contained Heart Implanted
A patient on the brink of death has received the world’s firstself-contained artificial heart—a battery-powered device about the size of asoftball that runs without the need for wires, tubes or hoses sticking out ofthe chest.
Two surgeons from the University of Louisville implanted thetitanium and plastic pump during a sever-hour operation at Jewish HospitalMonday. The hospital said the patient was “awake and responsive” Tuesday and restingcomfortably. It refused to release personal details.
The patient had been expected to die within a month without theoperation, and doctors said they expected the artificial heart to extend theperson’s life by only a month. But the device is considered a major step towardimproving the patient’s quality of life.
The new pump, called AbioCor, is also a technological leap from themechanical hearts used in the 1980s, which were attached by wires and tubes tobulky machinery outside the body. The most famous of those, the Jarvic-7, usedair as a pumping device and was attached to an apparatus about the size of awashing machine.
“I think it’s potentially a major step forward in the artificialheart development,” said Dr. David Faxon, president of the American heartAssociation. However, he said the dream of an implantable, permanent artificialheart is not yet a reality: “This is obviously an experimental device whoselong-term success has to be demonstrated.” Only about half of the 4,200 Americanson a waiting list for donor hearts received them last year, and most of therest died.
Some doctors, including Robert Higgins, chairman of cardiology atthe Medical College of Virginia in Richmond, said artificial hearts areunlikely to replace donor hears.
“A donor heart in a good transplant can last 15 to 30 years,” hesaid. “It’s going to be hard to replace that with a machine.”
The AbilCor has a 2-pound pumping unit, and electronic controls thatadjust the pumping speed based on the body’s needs. It is powered by a smallbattery pack worn outside the body that transmits current through the skin.
