(LOS ANGELES) -- Arnold Schwarzenegger is in stable condition after undergoing heart surgery in Los Angeles, his representative has confirmed.
According to a tweet from Daniel Ketchell, the former California governor underwent a planned procedure at Cedars-Sinai Medical Center in Los Angeles on Thursday to replace a pulmonic valve that had previously been replaced in 1997 due to a congenital heart defect.
Although Schwarzenegger had chosen a less invasive method, an open-heart surgery team was standing by just in case.
"Governor's Schwarzenegger's pulmonic valve was successfully replaced and he is currently recovering from the surgery and is in stable condition," Ketchell's statement read. "We want to thank the entire medical team for their tireless efforts."
According to the Mayo Clinic, the pulmonary valve is one of four valves that regulate blood flow to the heart, and if it malfunctions, it can force the heart to work harder than usual to supply the body with blood. Schwarzenegger, 70, said in 1997 that he had not experienced any discomfort prior to his procedure.
"Choosing to undergo open-heart surgery when I never felt sick was the hardest decision I've ever made," Schwarzenegger said in a statement at that time. "I can now look forward to a long, healthy life with my family."
