When Madam Christine Chia had kidney failure in 2007, her husband, Mr Simon Ong, donated one of his kidneys to her.
They then spent nine years preparing for the possibility of her death, knowing that transplanted kidneys come with an expiry date.
Madam Chia, 43, died at the Singapore General Hospital on Tuesday (Oct 18) from heart failure, which had also led to complications with her donated kidney.
