Robin Williams is due to make a complete recovery within the next eight weeks after having undergone heart surgery on March 13, according to a statement released by his publicist. “Mr. Williams’ operation went extremely well and we expect him to make a full recovery,” said Cleveland Clinic staff cardiothoracic surgeon A. Marc Gillinov. “The 3-1/2-hour heart surgery was conducted to replace his aortic valve, repair his mitral valve, and correct his irregular heart beat.”

Williams, whose comedy show “Weapons of Self-Destruction” had to be postponed until the fall, said in a statement, “The professionals at the University of Miami Hospital and ultimately at the Cleveland Clinic were all fantastic. I can’t thank them enough for their kindness and dedication while I was in their care. I must also thank all the people who have expressed their love and concern for me. I have been deeply touched by their support. I got some great new material for the tour and can’t wait to get back on the road. I’m thinking the next leg of the tour will be ‘Weapons of Self-Destruction and Reconstruction!'”
