Arnold Schwarzenegger is not as invincible as his movie roles make him seem.

TMZ first reported that the actor and former "Governator" of California needed to undergo emergency open-heart surgery Thursday afternoon. The circumstances behind the procedure are not clear, but it's not the first time Schwarzenegger has had an issue with the health of his heart. Thankfully, he is said to be recuperating from the surgery, meaning he'll be back to terminating enemies in no time at all.

Schwarzenegger under the knife

The 70-year-old reportedly went to Cedars-Sinai Hospital on Thursday in need of a catheter valve replacement.

The procedure surrounding that is experimental in nature, and Schwarzenegger was faced with complications. Because of those complications - which doctors were reportedly prepared for - the famed actor and politician quickly underwent open-heart surgery in a procedure that lasted several hours.

He came out of the woods on the other side, though. All reports on Friday suggest he is in stable condition. Reports don't discuss whether or not the initial procedure was successful or not, although the complications suggest it may need to have been ditched for the sake of saving Schwarzenegger's life.

Heart surgery is beginning to become a common endeavor for him. In 1997, he also underwent heart surgery, having an aortic valve replaced, despite the somewhat optional nature of the procedure at that point in time. Many alleged that his suspected steroid use - he's a former bodybuilder - was the reason heh ad to have heart surgery in the late '90s.

Schwarzenegger denied those claims though, saying that the condition was congenital.

What Schwarzenegger is up to

Ever since he stepped down as Governor of California, Schwarzenegger has remained politically active. He's recently discussed tackling big oil companies and has commented on the state of the Republican Party, comparing it to the Titanic.

His film career, meanwhile, keeps on rolling along. There's a possibility that he'll star in the next installment of "The Expendables," depending on the status of Sylvester Stallone. He's also set to be in the next "Terminator" movie, slated for release in 2019. There are no signs of slowing down for the 70-year-old renaissance man.

So don't worry too much about this latest setback for Schwarzenegger. As he once famously said, "I'll be back." There's no reason to think that won't be the case now.
