World’s first heartless human was able to live without a pulse

A man, who was dying from a heart condition and was given only 12 hours to live, was up and talking after doctors removed his heart and replaced it with a device that allowed blood to circulate in his body without a pulse.

In 2011, a 55-year-old man named Craig Lewis was suffering from amyloidosis, a rare autoimmune disease that causes a build-up of abnormal proteins and results in rapid heart, kidney and liver failure.
