(CNN)Not many people would postpone lifesaving heart surgery.
But Stevie Wisz did just that in order to fulfill a once-in-a-lifetime opportunity: winning a college softball national championship.
Wisz was diagnosed as an infant with aortic stenosis, a heart condition that causes the narrowing of the aortic valve and restricts blood flow from the left ventricle to the aorta. She underwent open-heart surgeries at the ages of 9 and 15. In January, she was told that she required a third.
However, Wisz had her sights set on bigger things.
A senior at the University of California, Los Angeles, Wisz was determined to finish her final year and earn her degree in biology. She also wanted to help the Bruins win their 12th NCAA softball championship.
On June 4, Wisz fulfilled her goals, helping the team win its first title since 2010; UCLA defeated Oklahoma 5-4 on a walk-off single. And a little more than a week after that, she walked across the stage and received her bachelor's degree.
Then came the tough part.
On Friday, Wisz underwent open-heart surgery. Her pulmonary valve was transplanted to her aorta, and a cadaver valve was inserted into the pulmonary valve.
