When Catherine Artz was born during a blizzard in South Dakota, her parents had no idea how quickly their joy would turn into fear.
Andrea and Wyatt Artz welcomed Catherine on March 4, 2025, after what had been a completely normal pregnancy and delivery.
But just five minutes after birth, doctors noticed that Catherine’s oxygen levels were dangerously low.
She was experiencing serious heart, lung and kidney complications linked to pulmonary hypertension. Doctors needed to transfer her to a hospital with a higher level of specialized care, but the blizzard made that impossible for hours.
Once the weather cleared, Catherine was flown to Sioux Falls and admitted to Sanford Children’s Hospital.
Doctors discovered that the right side of her heart was underdeveloped and that pressure in her heart and lungs was dangerously high.
She was placed on a heart-lung bypass machine and received dialysis, but her condition continued to deteriorate.
At one point, her parents were told she might not survive the night.
A priest came to the hospital and baptized Catherine, then prayed with her family.
After that terrifying period, Catherine slowly began to improve.
Her doctors said she had “beat the odds.”
But her journey was far from over.
Catherine spent 107 days in the hospital before finally going home on June 18, 2025.
Today, she is doing well, playing outside, enjoying time with her sisters and even stopped using her feeding tube.
And now, the little girl whose life began with such uncertainty is preparing for another milestone.
Catherine is about to become a big sister.
Her mother is expecting their fourth child just eight days after Catherine’s first birthday.
From a newborn doctors feared might not survive the night to a thriving little girl preparing to welcome a sibling, Catherine’s first year has been anything but ordinary.
