First human-to-human heart transplant

Barnard-led team performs the first human-to-human heart transplant

A car collision on 2 December killed Edward Darvall's wife and fatally injured his daughter. He consented to donating Denise's heart and kidneys.

Groote Schuur, past midnight

Surgery began shortly after midnight on 3 December 1967 at Groote Schuur Hospital in Cape Town. Christiaan Barnard led a multidisciplinary University of Cape Town team that removed Louis Washkansky's irreparably damaged heart and put Denise Darvall's in its place.

Just before 6 a.m., the transplanted heart was electrically shocked and began beating in Washkansky's chest. It was the first human-to-human orthotopic heart transplant.

The donor and the consent

Darvall, 25, was struck by a car on 2 December and certified as having a lethal brain injury. Her father, Edward Darvall, consented to donation of her heart and kidneys after the same collision killed his wife.

The circumstances were legally and ethically fraught: formal brain-death and transplant statutes did not yet exist in South Africa.

Eighteen days

Washkansky, given as 54 in Barnard's contemporaneous clinical report and as 53 in some later histories, regained consciousness with a functioning donor heart.

The intensive immunosuppression intended to prevent rejection left him highly vulnerable to infection. He died of pneumonia on 21 December, 18 days after the operation.

What the sources leave uncertain

Sources variously call Washkansky 53 or 54. Barnard’s contemporaneous clinical report says 54, while later UCT histories sometimes say 53.
Published accounts give inconsistent durations and team sizes for the operation, so those figures have not been used as definitive facts.
