Michael and Kayla Petrilli are hoping for a “miracle” for their toddler.

When Kayla gave birth to her son, Alexander, in Florida in December 2023, he was born with a serious congenital heart disease known as transposition of the great arteries (TGA) — when the two main arteries leaving the heart are switched, according to the Mayo Clinic.

Years later, amid ongoing complications, the now-2-year-old boy is in need of a “rare” combination of a heart transplant and double-lung transplant at Texas Children’s Hospital, where he has been receiving care in Houston, the parents wrote on a GoFundMe page.

Funds raised will cover the costs of medical bills, food, gas and other expenses accrued during Alexander’s complicated health journey.

“He’s been in and out of the hospital because he’s had heart failure this whole time, so any cold or any little bug he gets takes him down more than just a normal kid,” Kayla told Texas news outlet KHOU.

The Petrilli family ended up in Houston after Alexander suffered a medical episode in December. His father recalled “giving him CPR at 4:45 [a.m.]” and hopping on an emergency medical jet in Florida to rush to Texas.

Kayla recounted the scary moment on GoFundMe, writing, “Alexander woke up with a scream in the middle of the night, held his breath and went completely limp.”

“I grabbed him and started chest compressions in my arms while I ran across the house to wake Michael up,” she continued.

Added Kayla, “I got Alexander on the floor and continued CPR while Michael called 911. He was so lifeless. It felt like forever until he took a breath.”

Alexander had suffered a “pulmonary hypertension crisis,” which led to a cardiac arrest, the mother explained.

Texas Children’s Hospital accepted Alexander’s case and soon sent the medical jet to Tampa to pick up the boy and his father.

“I stayed back to deal with the house stuff … and to get me and the kids packed to drive from Florida to Texas with my mom later that week,” Kayla remembered, also thanking friends and family who assisted.

“Eight months later, we’re here,” Michael recently explained to KHOU.
