Arnold Schwarzenegger posts a picture of himself from the hospital bed.

Arnold Schwarzenegger is recovering after undergoing heart surgery.

The Terminator star told fans he feels “fantastic” after being given a new aortic valve.

The 73-year-old was given a new pulmonary valve in 2018 to replace the one he received in 1997, due to a congenital heart defect.

In a post to social media, Schwarzenegger thanked doctors at the Cleveland Clinic in Ohio, and said he had been enjoying the local sights since his operation.

Photos showed him in a hospital bed with his thumbs up, and other pictures of him exploring the area.

“Thanks to the team at the Cleveland Clinic, I have a new aortic valve to go along with my new pulmonary valve from my last surgery,” he wrote.

“I feel fantastic and have already been walking the streets of Cleveland enjoying your amazing statues. Thank you to every doc and nurse on my team!

Schwarzenegger’s son Patrick commented on the Instagram post, joking: “PLEASE DON’T GO WORK OUT TODAY.”
