The Short Answer: Dr Christiaan Barnard transplanted the heart of Denise Darvall into Louis Washkansky at Groote Schuur Hospital in Cape Town, South Africa. Washkansky survived 18 days before dying of pneumonia, but the operation proved that heart transplantation was surgically possible.

Before 3 December 1967, replacing a human heart was considered impossible by most of the medical establishment. The heart was not just an organ — it was symbolic, almost sacred. The idea that it could be removed from one person and placed inside another seemed closer to science fiction than clinical reality.

The Operation That Changed Everything

Louis Washkansky was a 54-year-old grocer from Cape Town suffering from end-stage heart failure and diabetes. He had little time left. Denise Darvall, a 25-year-old woman, was fatally injured in a car accident. Her father gave consent for her heart to be donated.

Barnard and a team of approximately 30 staff operated through the night. The procedure took nine hours. When Washkansky's new heart was stimulated with an electric shock, it began beating on its own. The world's first heart transplant was complete.

Washkansky initially recovered well and was able to talk and read newspapers. However, the immunosuppressive drugs used to prevent rejection weakened his immune system, and he developed double pneumonia. He died on 21 December 1967, eighteen days after the transplant.

The Legacy

Despite Washkansky's death, the operation proved the concept was surgically viable. The challenge was immunology, not surgery. In the decades that followed, the development of cyclosporine and other anti-rejection drugs transformed heart transplantation from a desperate experiment into a routine procedure.

Today, over 5,000 heart transplants are performed worldwide each year, with one-year survival rates exceeding 85%. The average survival after a heart transplant is now over 12 years, with many patients living 20 years or more.
