A one-year-old baby named Owen Monroe received a successful partial heart transplant in a groundbreaking procedure at Duke University Medical Center.

The surgery involved transplanting only the portion of the heart containing the valves, enabling them to grow and function naturally.

This new procedure offers hope for children who are not candidates for traditional transplantation or valve replacement.

Owen had a rare congenital heart defect that can quickly lead to heart failure.

Owen's transplanted tissues are functioning well and growing along with his body.

This new treatment option could potentially increase the supply of donated organs for other patients.
