In a video that was uploaded to YouTube not too long ago, Arnold Schwarzenegger stated that the operation took place a number of years ago, right before he began working on Terminator: Dark Fate, which is scheduled to be published in 2019.
In his memory, Arnold Schwarzenegger recalled waking up after the operation and going to visit his physician, who informed him that the operation had not gone according to plan. According to the actor, the treatment that was planned to replace a heart valve was supposed to be very non-invasive; nonetheless, his doctors “made a mistake and poked through the heart wall.”
