The "Terminator" star posted a video on his official Twitter account and offered an update on his health, along with a tweet, "Thank you all for caring. We are moving forward!"
"I just want you to know that I'm feeling much better. I can't say, even with my positive attitude, that I'm great, because I'm not great yet. Great is a totally different level. But I'm good. I feel good. I get good care, good doctors, good nurses. Everything is fantastic," he said.
The video then showed the 70-year-old actor sitting in front of a chess board. He said he was playing the game to help "freshen my mind and my memory a little bit".
"And we move forward. So I will stay in touch with all of you. And thank you all for being such jewels," he added.
Last week, Schwarzenegger's spokesperson, Daniel Ketchell, had said that the actor "underwent a planned procedure to replace a pulmonic valve that was originally replaced due to a congenital heart defect in 1997."
He said Schwarzenegger's pulmonic valve was "successfully replaced" and that the star "is currently recovering from the surgery and is in stable condition".
