Arnold Schwarzenegger disclosed that he had open-heart surgery just last week.

The Terminator star, who has undergone several cardiac procedures before, announced Monday in his fitness-related newsletter, Arnolds Pump Club , that he now has a pacemaker and has become a little bit more of a machine.

Last Monday, I had surgery to become a little bit more of a machine: I got a pacemaker, he wrote in the newsletter, per ET . I have to tell you, just saying this to all of you goes against so much of my upbringing in Austria, where nobody ever talked about medical issues.

Everything related to healthcare was kept to yourself, Schwarzenegger, 76, continued.

The actor has been open about his bicuspid aortic valves, however, which according to Johns Hopkins Medicine is a type of abnormality in the aortic valve in the heart. Schwarzenegger said Monday that both his mother and grandmother died from this.

The former California governor reflected last year on a botched procedure from 2018 , when he was supposed to receive a noninvasive aortic valve replacement but a mistake mid-surgery led his doctors to perform open-heart surgery.

The former bodybuilding champion, whose lifelong genetic condition resulted in an irregular heartbeat, wrote Monday that he first got his valves replaced in 1997. Schwarzenegger explained that, at the time, his only option was open-heart surgery.
