Testing Stem Cells in Tiniest Hearts to Fight Birth Defect

(Associated Press) – The 4-month-old on the operating table has a shocking birth defect, nearly half his heart too small or even missing. To save him, surgeons will have to totally reroute how his blood flows, a drastic treatment that doesn’t always work. So this time they are going a step further. In a bold experiment, doctors injected donated stem cells directly into the healthy side of Josue Salinas Salgado’s little heart, aiming to boost its pumping power as it compensates for what’s missing.
