Berlusconi up walking after heart op

(ANSA) - Milan, June 23 - Ex-premier Silvio Berlusconi is up and walking after his heart operation nine days ago.
    A smiling Berlusconi took a male nurse's arm and was helped from his ward to the next at Milan's San Raffaele Hospital, where he chatted and quipped with fellow patients, sources said.
    The three-time premier and media mogul is expected to be in the San Raffaele for another 10 days or so, and back in action at the helm of his centre-right Forza Italia party after the August break. He had the June 14 operation on a life-threatening heart condition, a faulty aortic valve which was replaced with an artificial one.
