Rep: Robin Williams' surgery went well

LOS ANGELES, March 23 (UPI) -- Robin Williams has undergone heart surgery to replace his aortic valve, the U.S. actor and comedian's publicist said.

Usmagazine.com reported Monday that the 57-year-old entertainer is resting comfortably after having the operation. Various media reports said it took place March 13.

"Mr. Williams' operation went extremely well and we expect him to make a full recovery," Dr. A. Marc Gillinov, a staff cardiothoracic surgeon at the Cleveland Clinic, told the magazine. "The 3 1/2-hour heart surgery was conducted to replace his aortic valve, repair his mitral valve and correct his irregular heart beat. His heart is strong and he will have normal heart function in the coming weeks with no limitations on what he'll be able to do. ... A couple of hours after surgery, he was entertaining the medical team and making us all laugh."

Williams is to resume his "Weapons of Self-Destruction" comedy tour in the fall, Usmagazine.com said. He had to postpone dates after he experienced shortness of breath and was hospitalized this month.
