“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 10ng．term Success has to be demonstrated．”O(jiān)nly 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 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 1 5 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．
