There are 14,000 people in the United States waiting for a liver transplant. And if the country's medical centers continue to draw the vast majority of viable livers from deceased donors, only half of those waiting will receive a transplant. Fifteen to twenty-five percent of those waiting never will.

The University of Pittsburgh Medical Center hopes to change that through Living Donor Liver Transplants (LDLTs), which the hospital says are underpromoted and underutilized across the world.
