For the second time in his life, Iowa State men's basketball coach Fred Hoiberg is having open heart surgery.

Hoiberg recently announced that he will undergo an operation to replace his aortic valve later this week. The procedure will be performed at the Mayo Clinic in Rochester, Minn., on Friday (April 17, 2015).

“After my initial surgery to replace my aortic root 10 years ago, I knew that this was something that would need to be done at some point,” Hoiberg said. “My valve has severe regurgitation and the time has come to get it replaced. I am hopeful that this will be my last surgery and I’m looking forward to getting this behind me.”

When he was playing basketball at Iowa State, Hoiberg learned that he had an enlarged bicuspid aortic valve. The enlargement eventually grew to the extent that it required attention, so Hoiberg underwent open heart surgery in 2005. The operation abruptly ended his 10-year playing career in the NBA.

As a result of the initial operation, doctors inserted a permanent pacemaker in Hoiberg's left shoulder. Last July, he had the pacemaker's batteries replaced during a procedure at the Mayo Clinic.

On Friday, Hoiberg is getting a mechanical valve that requires being on blood thinners the remainder of his life. He's expected to be hospitalized for a week, before returning home to continue recovery. The anticipated recovery time is four-to-six weeks.

Hoiberg recently finished his fifth season as Iowa State’s head coach. He has guided the Cyclones to a school-record four consecutive NCAA Tournament appearances and back-to-back Big 12 Conference tournament titles. Hoiberg owns a 115-56 career record.
