After more than 22 months at Mayo Clinic Children's, 13-year-old Ava Weitl went home to Iowa. She and her family were met with tears and cheers as dozens of members from her care team, who are now considered friends of the family, said goodbye and wished her well.
This was a day Ava had been looking forward to after a long journey with heart failure, two lifesaving extracorporeal membrane oxygenation (ECMO) therapies, a heart transplant, kidney failure and a kidney transplant.

Born with hypoplastic left heart syndrome (HLHS), a life-threatening condition where the left side of the heart is severely underdeveloped, Ava faced three open-heart surgeries before she would reach her 5th birthday. Within 90 minutes of her birth, her first surgery was performed. Her second surgery was completed months later, but the third, typically required for HLHS patients between the ages of 3 and 4, was not possible due to other medical concerns.
For a handful of years, Ava's care team monitored her to see what her body would do. During that time, Ava felt good and was "defying the odds," as her mom, Christina DeShaw, would say.
It was in 2021, during third grade, when Ava began to show signs of her heart and lungs struggling. While cardiac catheterization improved the blood flow to her lungs, it was a temporary improvement, and by early 2023, doctors determined a heart transplant was her only option.
Officially listed for a heart transplant in February 2023, Ava's condition worsened, leading to hospitalization at Mayo Clinic in September 2023. That hospital stay was the start of her long journey of constant monitoring and tests, and it wasn’t easy on her family as they navigated life split between Minnesota and Iowa.
In December 2023, Ava's condition took a critical turn. Ava was placed on life-sustaining ECMO, which provides heart and lung support when those organs are failing. Then, Feb. 26, 2024, the call came: a donor heart became available. The surgery was successful, but postoperative challenges arose.
Weeks later, complications with her lungs led to a return to ECMO for three months. She also needed a tracheostomy placed. While trying to save her lungs, her kidney function began to fail, leading to another gift of life — a kidney transplant on Jan. 25, 2025, thanks to a donation from her uncle through a kidney exchange with the National Kidney Registry.
"She's a walking miracle," her mother says. "We can't even wrap our heads around what she's been through."
Ava is excited to be home with her parents, Christina and Brad, her twin brother, Aiden, and her younger brother, Miles. She says she looks forward to hanging out with friends, going back to school and having a barbecue with her family.
