First Heart Transplant
Christiaan Barnard performed the first successful human heart transplant in Cape Town
December 03, 1967
The Operation the World Watched
On December 3, 1967, South African surgeon Christiaan Barnard led a team of 30 people in a nine-hour operation at Groote Schuur Hospital in Cape Town, transplanting the heart of a 25-year-old car accident victim named Denise Darvall into a 54-year-old dentist named Louis Washkansky. The operation succeeded. Washkansky woke up, spoke to his wife, and told journalists he felt fine. He survived for 18 days before dying of pneumonia — his immune system suppressed by drugs to prevent rejection.
The Science That Made It Possible
Heart transplantation required solving three problems simultaneously: keeping a patient alive with their chest open (solved by the heart-lung bypass machine), reattaching a heart's plumbing precisely enough to work, and suppressing the immune system enough to prevent it from rejecting the foreign organ without leaving the patient completely defenseless. Barnard had trained in the US, where researchers had been working on these problems for years. He was the first to attempt it on a human.
Heart Transplants Today
Over the following years, improved anti-rejection drugs dramatically increased survival rates. Today around 6,000 heart transplants are performed worldwide each year, with patients living 10–15 years on average after surgery. The waiting list for donor hearts is far longer than the supply. Researchers are now testing pig hearts — genetically modified to reduce rejection — as a potential solution. The field that started with one operation in Cape Town continues to expand the boundaries of what medicine can do.
