Which South African surgeon performed the world's first human-to-human heart transplant in 1967?

Christiaan Barnard performed the world's first human-to-human heart transplant in 1967.

The South African cardiac surgeon carried out the operation at Groote Schuur Hospital in Cape Town on December 3, 1967. Barnard's patient was Louis Washkansky, a 54-year-old grocer with severe heart disease. The donor was Denise Darvall, a young woman who had suffered fatal injuries in a road accident and was declared brain-dead.

The operation lasted about five hours and involved a team of roughly 30 staff members, including Barnard's brother Marius. Washkansky regained consciousness and was able to speak with his wife, but he died 18 days later from pneumonia. The immunosuppressive drugs used to prevent rejection weakened his ability to fight the infection.

Barnard's achievement built on earlier experimental work by surgeons such as Norman Shumway and Richard Lower. In 1964, James Hardy had transplanted a chimpanzee heart into a human patient, but that was a human-to-animal transplant, not a human-to-human procedure. Barnard's breakthrough made heart transplantation a clinical possibility, although early results were limited by organ rejection and inadequate immune-suppressing medicines.
