Prince Phillip visited by The Queen at Papworth Hospital after his emergency heart surgery

Prince Phillip, the Duke of Edinburgh, has been visited by The Queen at Papworth Hospital following his emergency heart surgery to treat a blocked coronary artery.

The Queen arrived at the hospital this morning from her Sandringham estate, where the Royal family is spending Christmas.

The Duke of Edinburgh was this morning recovering after being airlifted to hospital for emergency heart surgery.

Prince Phillip was flown to the specialist cardiothoracic unit, near Cambridge, in a RAF search and rescue helicopter after being taken ill at Sandringham with serious chest pains last night.

After “precautionary” tests, Prince Philip underwent what was described as a “minimally invasive procedure” known as coronary stenting.

This involves placing a tube in the coronary arteries that supply the heart, to keep them open in the treatment of heart disease. Stents reduce chest pain and have been shown to improve survival rates in the event of an acute heart problem.

Today Buckingham Palace said Prince Phillip “had a good night” and was currently under surveillance in the world-famous Papworth Hospital after emergency surgery for a blocked coronary artery.

He is expected to be visited by members of his family this morning.

There was no indication when he would be discharged, but medical experts have said that many patients can leave hospital a day after undergoing the procedure, providing there are no complications.

Dr. Simon Davies, a cardiologist at the Royal Brompton Hospital in London, said: “The pain was from the heart. It means that one or more of the coronary arteries was badly narrowed or perhaps blocked.

“That meant that the blood was not passing through that artery so the muscle was starving of oxygen and in danger of dying, in other words a heart attack, or was on the verge of one.”

In view of his age, Prince Phillip, who still conducts more than 350 engagements each year, will remain in hospital for a day or so for further monitoring.

Buckingham Palace said in a statement last night: “His Royal Highness the Duke of Edinburgh was taken to Papworth Cardiothoracic Centre this evening from Sandringham House for precautionary tests after experiencing chest pain.

“Following tests at Papworth the Duke of Edinburgh was found to have a blocked coronary artery which had caused his chest pains. This was treated successfully by the minimally invasive procedure of coronary stenting. Prince Philip will remain in hospital for observation for a short period.”

It is believed the Duke of Edinburgh was flown to the hospital, which is around 60 miles away from the Sandringham estate, by a Sea King helicopter from RAF Wattisham, near Stowmarket in Suffolk, where Prince Harry is based.
