Queen Elizabeth II's husband has undergone surgery for a blocked coronary artery, British royal officials said Friday.
A spokeswoman for Buckingham Palace said Prince Philip will remain in the hospital for "a short time" for observation after the "very minimally invasive procedure" to implant a coronary stent.
She would not say if other members of the royal family were with the Duke of Edinburgh and declined to comment further, speaking on customary condition of anonymity. A hospital spokeswoman referred all calls to the palace.
Philip, 90, was taken from Sandringham, the queen's sprawling estate in rural Norfolk, to the cardiac unit at Papworth Hospital in Cambridge earlier Friday for "precautionary tests" after suffering chest pains.
The queen's husband has been at Sandringham since Monday for the royal family's Christmas festivities, Buckingham Palace said. It was unclear if Philip's health would alter the royal family's plans for the weekend — which typically include a public appearance before church services and then a private family lunch.
