...removal of a substantial part of the heart can severely restrict a patient's activities. In extreme cases, the organ's pumping action can be reduced by as much as 60%. To avoid these debilitating consequences, Jones' surgeon, George Magovern, wanted to try something new: bolstering her weakened heart with a muscle transplanted from her back...
During the five-hour procedure, an Allegheny plastic surgeon detached a latissimus dorsi--a broad muscle that plays a nonessential role in controlling arm motion--from its connection points along the spine. Magovern slipped it into the chest cavity with the muscle's nerve system and major blood supply intact, then wrapped it around Jones' heart like a towel. After a week's recovery time, he began stimulating the transplanted skeletal muscle with a pacemaker, causing it to contract and help pump blood. Less than a year later, Jones reports that she can walk a mile or two without difficulty...
...skeletal muscle and cardiac muscle are structurally different. Heart muscle works continuously, using oxygen at a steady rate. It never tires. Skeletal muscle is designed for short bursts of intense effort and fatigues easily. Ten years ago, while operating on a patient whose pacemaker had slipped out of place, Magovern made a chance observation. The patient's chest muscle, stimulated by the misplaced device, had doubled in size and showed no signs of fatigue. Other researchers independently proved that skeletal muscles actually come to resemble their cardiac counterparts when electrically conditioned...
