The Norwegian palace confirmed to news wire NTB that the king was to leave hospital following the procedure three days ago.
“The king is in good form and will travel home from Rikshospitalet today,” the king’s doctor, consultant Bjørn Bendz, said in the statement.
The palace had confirmed during the weekend that the king was well after the procedure to fix an artificial valve he received during a previous operation in 2005.
Artificial valves of the type the king received have a life span of 10-15 years. As such, it is not uncommon for them to be replaced.
“His majesty the king is well after yesterday’s intervention. The king has been for a short stroll, and his condition is good,” Bendz said in a statement on Saturday.
Last month, the king spent a short time in hospital due to respiratory problems unrelated to Covid-19.
He is currently on indefinite sick leave, with his son Crown Prince Haakon deputising the king’s royal duties.
