(CNN)He may be known as a robot assassin. But in real life, he's only human.Arnold Schwarzenegger, the 73-year-old actor and former Republican governor of California, revealed on social media Thursday that he had undergone heart surgery.
In the post, which was shared on both Instagram and Twitter, Schwarzenegger shared that he had his aortic valve replaced at the Cleveland Clinic medical center in Ohio.
A faulty aortic valve isn't something you want to have considering that it helps blood flow out of the heart and through the rest of the body. It can also lead to aortic stenosis, and is more common as people age. Others, like Schwarzenegger, have heart problems their whole lives because of a congenital heart defect.
