Action-movie legend Arnold Schwarzenegger is awake and in good spirits following emergency heart surgery.The 70-year-old Hollywood icon, famous for starring in the Terminator and Predator franchises, underwent a catheter valve replacement on Thursday at Cedars-Sinai Hospital in Los Angeles, only for complications to arise which led to the emergency surgery. Currently resting, the former governor of California took to Twitter to update fans on his recovery.RELATED: Schwarzenegger Explains How Terminator 6 Will Save the Franchise

During the surgery, the valve apparently failed and, as a result, Schwarzenegger had to undergo emergency open-heart surgery. The former governor of California was reportedly born with a bicuspid aortic valve and already had surgery in 1997 to have a valve replaced. However, he was notified back then that the procedure would eventually have to be repeated, which led to this new procedure.

The ex-professional bodybuilder turned actor has been back on the big screen over the last few years after his tenure as governor ended, appearing in The Expendables franchise, garnering critical acclaim in 2015's zombie-thriller Maggie, as well as reprising his role as a cyborg in Terminator Genisys.
