LOS ANGELES (CBS SF & AP) — Former California governor and action movie star Arnold Schwarzenegger was recovering in a Los Angeles hospital after undergoing a heart surgical procedure, his spokesman confirmed Friday . 
  
 The 70-year-old former California governor had a scheduled procedure to replace a pulmonic valve on Thursday, according to Schwarzenegger’s spokesman, Daniel Ketchell. He was in stable condition on Friday. 
  
 “His first words were actually ‘I’m back,” so he is in good spirits,” Ketchell tweeted. 
  
 The operation was necessary to replace a valve that had originally been installed in 1997 for a congenital heart defect. 
  
 “That 1997 replacement valve was never meant to be permanent, and has outlived its life expectancy,” Ketchell said. 
  
 Schwarzenegger opted for a less-invasive catheter valve replacement procedure. 
  
 An open-heart surgery team was ready during the procedure, but Ketchell said their presence wasn’t unusual in such circumstances. 
  
 Last week, Schwarzenegger showed no signs of ill health at an event in Los Angeles where he teamed up with Ohio Gov. John Kasich to talk about their vision of future for the GOP. 
  
 The two veteran politicians urged the GOP to move more toward the center. Their future vision of the GOP would be a party of inclusiveness, a kinder tone and a willingness to work with Democrats on immigration and climate change to shape the agenda. 
  
 “I’m sick of politics,” Kasich, a potential 2020 presidential candidate, said at one point at a forum in Los Angeles, eliciting a round of applause. 
  
 Knitting his fingers together repeatedly for emphasis, he said people need to work together, and he recalled President Ronald Reagan working with Democrats on Social Security. 
  
 Reagan was no doctrinaire, Kasich said, but “operated to fix things.” 
  
 In an obvious dig at Trump, Schwarzenegger said that voters were looking for answers but that the party “is giving them Twitter fights instead.” The president’s name, however, came up only sparingly Wednesday. 
  
 “We can’t be afraid to talk about health care,” Schwarzenegger said. “We can’t be afraid to talk about the environment.” ||||| Arnold Schwarzenegger, one of Hollywood's biggest and highest-paid stars, had elective heart surgery Wednesday to replace an aortic valve, his spokeswoman said. 
  
 Schwarzenegger, 49, star of the "Terminator" movies, is expected to make a full recovery and will not be required to take any heart medication after the surgery, said spokeswoman Catherine Olim. 
  
 Schwarzenegger, who won the Mr. Universe contest five times and retired undefeated as Mr. Olympia after seven victories, has acknowledged using steroids when he was a bodybuilder. 
  
 But Olim said, "Steroids have nothing to do with this. . . . This is a congenital condition that's existed in his family. We expect a very short recovery period." ||||| Arnold Schwarzenegger Undergoes Emergency Heart Surgery 
  
 Arnold Schwarzenegger Undergoes Emergency Heart Surgery 
  
 EXCLUSIVE 
  
 10:40 AM PT -- Arnold's people just told us the following ... the procedure was "to replace a pulmonic valve that was originally replaced due to a congenital heart defect in 1997. That 1997 replacement valve was never meant to be permanent and has outlived its life expectancy, so he chose to replace it yesterday through a less-invasive catheter valve replacement. During that procedure, an open-heart surgery team was prepared ... in case the catheter procedure was unable to be performed." 
  
 The rep says Arnold's recovering from surgery and is in stable condition. His first words after waking up: "I'm back." Naturally. 
  
 Arnold Schwarzenegger has undergone emergency open-heart surgery ... TMZ has learned. 
  
 Sources connected to Arnold tell TMZ, the 70-year-old Schwarzenegger went to Cedars-Sinai Thursday for a catheter valve replacement. We're told the surgery is somewhat experimental and he developed complications. 
  
 Doctors were prepared in case the catheter valve replacement failed ... and quickly decided Arnold needed emergency open-heart surgery, which we're told lasted several hours. 
  
 This is not the first time Arnold has gone under the knife for heart surgery. He had an aortic valve replaced in 1997. At the time doctors didn't feel the procedure was urgently needed, but Arnold decided to do it while he was still young. He also said at the time the condition was congenital and had nothing to do with steroids. 
  
 As for his condition ... we're told he's stable. |||||

Arnold Schwarzenegger had emergency open-heart surgery Thursday in Los Angeles, TMZ reports. Sources tell the outlet that the 70-year-old action star was at Cedars-Sinai for a catheter valve replacement. There were complications from the surgery, and doctors decided Schwarzenegger needed the emergency operation. Sources say the former California governor is stable and recovering. Schwarzenegger had a previous heart surgery to replace an aortic valve in 1997, which he blamed on a congenital condition. "I've never felt sick or had any symptoms at all, but I knew I'd have to take care of this condition sooner or later," the Los Angeles Times quotes him as saying at the time. "I said to the doctors, 'Let's do it now, while I'm young and healthy.'" CBS SF reports Schwarzenegger seemed in fine health last week during an event in Los Angeles with Ohio Gov. John Kasich. The two talked about the need for a kinder and more inclusive GOP that was willing to work with Democrats on certain issues. “We can’t be afraid to talk about health care,” Schwarzenegger said at the event. “We can’t be afraid to talk about the environment.”
