Arnold Schwarzenegger is in "stable" condition after undergoing heart surgery, according to his rep.
"That's the most important part," he said.
TMZ reported Schwarzenegger underwent emergency open-heart surgery after developing complications from another procedure.
The emergency surgery is said to have taken several hours.
Sources said Schwarzenegger, who previously had an aortic valve replaced in 1997, went to Cedars-Sinai hospital Thursday for a catheter valve replacement.
The star experienced complications after the "somewhat experimental" procedure.
