1Researchers say a new method for heart transplants could increase the number of available organs and save more lives.
2Currently, most transplanted hearts come from donors who have been declared brain dead.
3This means the person no longer has signs of brain function after suffering a serious injury.
4In a brain death, machines can keep the body breathing and can provide oxygen to organs until they can be recovered and put on ice.
5But the new method would take hearts from medical cases known as circulatory deaths.
6These cases are also known as donation after circulatory death, or DCD.
7Circulatory deaths happen when a person has a nonsurvivable brain injury, but still has some brain function.
8In these cases, family members can decide to withdraw all life support measures.
9This means organs go without oxygen for a time before they can be recovered.
10Currently, kidneys and some other organs are taken from people suffering circulatory deaths.
11But doctors have resisted using hearts because of possible organ damage from a lack of oxygen.
12A new study suggests that hearts might also be recoverable from cases of circulatory deaths.
13Researchers at North Carolina's Duke University School of Medicine led the study, which was recently published in the New England Journal of Medicine.
14The researchers said using hearts from circulatory deaths could possibly give thousands more patients a chance at a lifesaving transplant.
15And it could increase the number of donor hearts by 30 percent.
16"Honestly if we could snap our fingers and just get people to use this, I think it probably would go up even more than that," transplant doctor Jacob Schroder told The Associated Press.
17"This really should be standard of care," he said.
18With the new method, doctors can remove hearts in circulatory deaths and put them in a machine that "reanimates" them.
19This process pumps blood and nutrients through the heart as they are being transported.
20The organs can also be tested to make sure they are effectively functioning before they are transplanted.
21The study involved multiple hospitals around the country, as well as 180 transplant patients.
22Half the patients received DCD hearts and half were given hearts from brain-dead donors that were transported on ice.
23Survival rates six months later were about the same - 94 percent for recipients of cardiac-death donations and 90 percent for those who got the usual hearts, the researchers reported.
24The findings are exciting and show the possibility "to increase fairness and equity in heart transplantation..." said Dr. Nancy Sweitzer.
25She is a heart transplant specialist at Washington University in St. Louis.
26 Sweitzer, who was not part of the study, said she thinks the new method will permit more people with heart failure to receive lifesaving treatment.
27In the U.S. last year, 4,111 heart transplants were performed.
28While this was a record number, it is not nearly enough to meet the need.
29Hundreds of thousands of people suffer from advanced heart failure but many are never offered a transplant.
30Still others die waiting for one.
