Voronezh State University
In 1934, Demikhov began studying at the Voronezh State University, where in 1937 he created the world's first artificial heart and successfully implanted it into a dog (which survived for two hours after the surgery). A description of this groundbreaking work was published in April 1938 in the university's student newspaper, and it was presented to the other students at a scientific conference the following month. He then transferred to the Biology Faculty of Moscow State University, where he wrote his first scientific work, and graduated with honors in August 1940.
