First Self-contained Heart Implanted
A patient on the brink of death has received the world’s first self-contained artificial heart— 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 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 AbilCor 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.
Approximately two thousand one hundred patients received heart implantation in America last year.
选项
A、Right
B、Wrong
C、Not mentioned
答案
A
解析
题意:去年美国有大约2,100位病人接受了心脏移植手术。根据文章第五段最后一句Only about half of the 4,200 Americans...received…可知,等待别人捐献心脏的4,200位病人中大约有一半的人得到捐献,所以题干叙述正确。故本题选A。
