Stephanie Fae Beauclair (October 14, 1984 – November 15, 1984), better known as Baby Fae, was an American infant born in 1984 with hypoplastic left heart syndrome.
She became the first infant subject of a xenotransplant procedure and first successful infant heart transplant, receiving the heart of a baboon.
Though she died within a month of the procedure, she lived weeks longer than any previous recipient of a non-human heart.
