Fred Hoiberg recovering after heart surgery

DES MOINES, Iowa -- Iowa State says coach Fred Hoiberg has undergone open-heart surgery to replace an aortic valve.

Hoiberg had the surgery Friday at the Mayo Clinic in Rochester, Minnesota.

Dr. Rakesh Suri said the operation was a success, adding that "Hoiberg is in recovery and doing very well himself."

Hoiberg retired from the NBA after the 2004-05 season because of heart issues. He just completed his fifth season at Iowa State, leading the Cyclones to four straight NCAA tournament appearances and back-to-back Big 12 tournament titles.

He is expected to need about four to six weeks to recover.
