Jimmy Kimmel’s Son Billy Undergoes Third Open-Heart Surgery, Inspires Family with Hopeful Recovery

Jimmy Kimmel Shares Son Billy’s Life-Threatening Heart Journey: From Surgery to Resilience

In April 2017, Jimmy Kimmel took the stage of his late-night show to deliver more than laughs. The host shared a deeply personal story: his newborn son, Billy, had been diagnosed with tetralogy of Fallot with pulmonary atresia, a rare and serious congenital heart defect that impairs the heart’s ability to pump blood. Born just days before the announcement, Billy required urgent open-heart surgery to survive.

Kimmel described the initial diagnosis as overwhelming, saying, “It was like the world stopped. All I could think about was, ‘How do I protect this tiny human I just met?’” The surgery, performed at Children’s Hospital Los Angeles, was complex and risky. Kimmel recalled pacing hospital corridors, grappling with fear and helplessness, while placing trust in the expertise of the medical team.

He shared the harrowing details on air with raw honesty—the long hours, the uncertainty, and the emotional relief when Billy emerged from surgery fragile but alive. Using his platform, Kimmel also advocated for accessible healthcare, stating, “No parent should ever have to choose between their child’s life and their bank account.”

Billy’s journey did not end there. By 2024, he had undergone his third open-heart surgery. Despite repeated medical challenges, Billy is thriving. Kimmel describes him as “the toughest (and funniest) 7-year-old we know,” highlighting both his resilience and the close bond within their family.

Throughout the ordeal, Kimmel’s wife, Molly McNearney, and their older children, Jane and Katie, were crucial sources of support and levity, reminding the family of life’s everyday joys even in hospital rooms.

Billy’s story has become a testament to the power of parental love, medical expertise, and resilience. Through Kimmel’s candid recounting—balancing humor with sorrow, and fear with hope—viewers gained an intimate look at the challenges of congenital heart disease and the strength families find in adversity.

Today, Billy’s journey continues, but his survival and spirit stand as a beacon for families everywhere, showing that courage, love, and laughter can endure even the most difficult trials.
