"Dr. Zbigniew Religa, a Polish doctor, anxiously watched a screen to check his patient's response after a heart transplant. The surgery was complex and lasted 23 hours. In the photo, you can see one of his colleagues who helped him with the operation asleep in the corner.

Dr. Religa was a trailblazer for heart transplants in Poland. The surgery was seen as nearly impossible at the time, but he took the risk, and the operation was successful."
