Baby Fae

Stephanie Fae Beauclair, better known as Baby Fae, was an American infant born in 1984 with hypoplastic left heart syndrome. On October 26, 1984, she became the first infant subject of a xenotransplant procedure and the first successful infant heart transplant, receiving the heart of a baboon. Though she died on November 15, within a month of the procedure, she lived weeks longer than any previous recipient of a non-human heart.
