In a remarkable act of generosity, a 10-year-old heart transplant patient became a life-saving hero for two toddlers through a groundbreaking series of surgeries.

In July, doctors at NewYork-Presbyterian Morgan Stanley Children’s Hospital performed a rare and miraculous operation that changed the lives of three children. Hend Almesafri, a young heart transplant recipient, received a new heart from a deceased donor. Instead of discarding her old heart, doctors utilized it to save two other children. Hend’s pulmonary valve was donated to 2-year-old John Catoliato, and her aortic valve to 3-year-old Teddy Carter.

Months later, all three children reunited at the hospital, where Hend surprised her “heart brothers” with gifts, leaving their families deeply moved. “You see these kids interacting, and you know people are good,” said John’s mother, Joanne Dowling.

John was born with a rare heart defect called truncus arteriosus, where his heart had only one exit instead of two. His mother, Joanne, found out about his condition during pregnancy and was heartbroken. Despite the fear, she never considered terminating the pregnancy. “I loved him from the minute I found out I was pregnant,” she said. “I knew that the doctors could fix him.”

After undergoing open heart surgery at just 5 days old, John faced a future of repeated surgeries. His artificial valve would never grow with him. The news of a potential transplant was a ray of hope. “It was a comfort to know that John might never need another open heart surgery,” Joanne shared.

When the call came that a heart was available, John’s parents felt both hope and anxiety. The next morning, they brought John to the hospital, reassured by the compassionate care of the medical team.

Teddy Carter was diagnosed with aortic stenosis at just 2 months old. His condition threatened to block blood flow to his heart, and multiple surgeries seemed inevitable. But the transplant changed everything. Teddy’s mother, Katie, expressed immense gratitude for the opportunity, saying, “We were just lucky to live in New York and have access to such incredible care.”

The surgeries performed were part of a complex and rare split-root domino heart transplant. One donor heart benefiting multiple recipients is almost unheard of, but the hospital’s skilled team made it possible.

The operations began at 8 a.m. and lasted nearly 20 hours, but each procedure was successful. Months later, the three families gathered to celebrate their children’s newfound health. “It was humbling,” said Joanne. “What can you give to someone who gave your child a chance to live?”

For the Catoliato and Carter families, Hend will always be more than just a fellow patient — she’s a hero. As Teddy’s father reflected on the experience, he shared a moment that encapsulated the miraculous nature of the journey: “We were in the car, and Teddy said, ‘My heart was broken, and now it’s fixed.’”

Through one heart’s journey, three lives were transformed — a testament to faith, selflessness, and the unyielding will to live.
