Former Australian prime minister Kevin Rudd is expected to undergo a surgery to get replaced a heart valve installed earlier.
Rudd will go under the knife for a heart surgery at a Brisbane hospital, local media said.
His wife Therese and daughter Jessica will be present by his side when he wakes after the procedure, which is expected to take four to six hours.
"We are truly grateful for all the prayers and kind messages of support we've received from around the country," the family said in a statement.
Rudd's daughter has returned home from Beijing to help care for her father after the operation that is scheduled for this afternoon.
The workaholic former prime minister will take an eight week break from his normally hectic schedule so he can make a full recovery.
Rudd's cardiologist, David Celermajer, was confident he would keep his high profile patient in bed and away from work.
Rudd had the initial heart valve replacement because his heart had been damaged by rheumatic fever when he was a child.
