C. Walton Lillehei

C. Walton Lillehei was a pioneering American heart surgeon who revolutionized heart medicine in the 1950s. He developed innovative techniques to perform open-heart surgeries, including the use of a temporary heart-lung machine to take over the functions of the heart and lungs during surgery. This technology allowed for more complex and successful surgeries, saving many lives. Lillehei's work laid the foundation for modern cardiac surgery and he is considered one of the key figures in making heart surgery safer and more effective. His contributions significantly advanced the treatment of congenital and acquired heart conditions.
