“Owen Monroe was 18 days old when he made history, becoming the first person in the world to receive a partial heart transplant…

In a study published Tuesday in the journal JAMA, his doctors will document another milestone: For the first time, the tissue used to fix Owen’s heart has grown, a long-sought goal of this type of repair.

At the time of his first operation, Owen’s heart was the size of a strawberry. Today, at 20 months of age, it’s about the size of an apricot – and the new valves and blood vessels have kept up with his growth, which means unlike most children born with the same defect, he may not need to have more risky heart surgeries throughout his life.”
