The human heart is an irreplaceable body organ that works really hard. It works really hard – the heart beats over 86,000 times per day and about 35 million times per year. Keeping this fact in mind, it isn’t surprising that at some point of our lives our hearts may fail.
In this case people need a heart transplant that will provide about 10 extra years of life. However, in most cases such transplantations don’t happen as there are no donors.
That is why two medics, Dr. Billy Cohn and Dr. O.H.Frazier have started an ambitious project. They are working to develop an artificial heart. It consists of two turbines that send a continuous flow of blood to the whole body. The permanent artificial heal has no pulse but the two researchers have found that it can sustain life.
In 2011 the doctors put the heart into a human. The patient was suffering from a rare autoimmune disease and survived for 6 weeks after the surgery. He died of kidney failure caused by his disease.
