Hollywood legend, Arnold Schwarzenegger, has undergone emergency open-heart surgery, according to US reports.
The 70-year-old underwent the medical procedure on Thursday, according to TMZ.
Schwarzenegger was scheduled to have a catheter valve replacement and developed complications, US reports say.
The procedure usually means the patient can avoid having open-heart surgery.
Doctors at Cedars-Sinai Hospital in LA reportedly decided an emergency open-heart operation was needed and Schwarzenegger was in theatre for several hours.
The former governor of California is believed to be in a stable condition.
Schwarzenegger is best known as the hardman of cult movies such as the Terminator and Conan the Barbarian.
He served two terms as California governor from 2003 to 2011 before returning to acting in The Expendables.
In May last year, Schwarzenegger was honoured in France with the Chevalier de la Legion d’Honneur, the country’s most prestigious medal, for his environmental work.
