Prince Philip, Duke of Edinburgh

Prince Philip, the Duke of Edinburgh and husband of Queen Elizabeth II, returned to the royal family's estate Tuesday morning after undergoing surgery for a blocked coronary artery.

Philip, 90, had spent the past four nights in Cambridge's Papworth Hospital following a successful stent procedure Friday, forcing him to miss the royal family's holiday festivities. "He is very much looking forward to rejoining his family," a Buckingham Palace rep said.

Philip did not grant interviews as he exited the hospital, but he smiled and waved to bystanders.

He was last hospitalized in April 2008, when he spent three days in a London hospital with a chest infection.
