The first successful operation on the heart was done in 1896 on a patient
with a stab wound to the heart. However, after that, not much was done. The
problem is that your body needs your heart beating all the time to pump blood to
the rest of your body. This problem was solved in 1953, when they developed a
pump that will take care of pumping blood to the body so that the heart can be
temporarily stopped. The first valve replacement was done in 1955 and the first
bypass was done in 1964.
