April 4

For those of you who, like me, are fans of dangerous, time-consuming heart surgery, on the 4th in 1969 Dr. Denton Cooley and Dr. Domingo Liotta, the designer of the first artificial heart, implanted it in a human.
Cooley is a member of the Serbian Academy of Sciences and Arts, in the Department of Medical Sciences. One question: Why?
Dr. Liotta is the founder and director of the Domingo Liotta International Foundation – Medical Corporation that is a non-profit organization dedicated to the Artificial Heart and Assisted Circulation research. He is the author of the book The Artificial Heart: The Frontier of Human Life.
