(NewMediaWire) - November 08, 2015 - ORLANDO, Florida - A new 3D computer modeling system may significantly improve a surgeon’s ability to select the best sized donor heart for children receiving heart transplants, according to research presented at the American Heart Association’s Scientific Sessions 2015.
Transplant centers currently assess compatibility of a potential donor heart by comparing the donor weight to the recipient weight and then picking an upper and lower limit based on the size of the patient’s heart on chest X-ray. But the assessment is not precise and variations in size and volume can have a major effect on the recipient’s outcome.
While survival in pediatric heart transplantation have improved, there are still too few donors to meet the demand, so “it is critical to optimize the range of acceptable donors for each child,” said study author Jonathan Plasencia, B.S., a Ph.D. student at Arizona State University’s Image Processing Applications Lab in Tempe, Arizona.
