Prince Philip, the husband of Queen Elizabeth, had an operation to relieve a blocked artery in his heart on Friday after being rushed to hospital with chest pains, Buckingham Palace said.
The Duke of Edinburgh was found to have a blocked coronary artery which caused his chest pains, the palace said in a statement. This was treated successfully by the minimally invasive procedure of coronary stenting.
A stent is a small tube inserted into a blood vessel to keep it open and avoid blockages. The stent is often fitted through a small incision in the chest during keyhole surgery.
Philip, 90, will remain in Papworth Hospital, eastern England, for a short period, the palace added.
