The 90-year-old Duke of Edinburgh, husband of Queen Elizabeth II, has been successfully treated for a blocked coronary artery Friday and will stay in the hospital overnight, Buckingham Palace said in a statement.
Earlier on Friday night, Prince Philip was flown to the Papworth Hospital in Cambridgeshire after suffering chest pains.
He was then diagnosed with a blocked coronary artery and underwent keyhole surgery, which is minimally invasive.
Prince Philip will “remain under observation in hospital for a short period,” according to Buckingham Palace’s statement.
The royal family was gathering at Sandringham House in Norfolk to celebrate Christmas, when the Duke experienced chest pains.
The Duke had just completed an 11-day official tour to Australia with the 85-year-old Queen. He has been in relatively good health, but was reported to have experienced chest pains before.
The last time Prince Philip was hospitalized was in April 2008, when he spent three days in London with a chest infection.
