"Yesterday, Governor Schwarzenegger underwent a planned procedure at Cedars-Sinai to replace a pulmonic valve that was originally replaced due to a congenital heart defect in 1997," Kitchell said in the Friday statement. "That 1997 replacement valve was never meant to be permanent, and has outlived its life expectancy, so he chose to replace it yesterday though a less-invasive catheter valve replacement. During that procedure, an open-heart surgery team was prepared, as the frequently are in these circumstances, in case the catheter procedure was unable to be performed. Governor Schwarzenegger's pulmonic valve was successfully replaced and he is currently recovering and is in stable condition."
On Sunday, Ketchell said Schwarzenegger "had a planned catheter surgery that used the backup plan of open heart surgery to successfully replace the valve."

Ketchell said that when Schwarzenegger woke from surgery, his first words were a nod to his “Terminator” catchphrase.
"His first words were actually 'I'm back,' so he is in good spirits," Ketchell said Friday.
