The family of Pakistan's Prime Minister Nawaz Sharif says he has successfully undergone open-heart surgery in London -- the 66-year-old's second major cardiac medical procedure in five years.
"Surgery successful," his daughter Maryam Nawaz Sharif said on Twitter on May 31.
"All arteries successfully grafted," she also said.
She posted a picture of Sharif lying in an intensive care unit bed with his eyes closed and said he was "stable."
Pakistan's prime minister is expected to stay in the hospital for about a week to recover before returning home.
Earlier, Maryam said the premier was suffering from complications following a 2011 procedure to trim excess material from his arteries.
Sharif was elected in May 2013 as prime minister for a third time.
