Man lives without a pulse after doctors invent new artificial heart
Because of the chronic shortage, thousands of people awaiting heart transplants die annually. Artificial hearts are one of the most reliable ways of resolving difficulties facing patients with heart disease.
A U.S. research team has recently come up with a resolution of a long-standing problem facing the medical industry by developing an artificial heart that continuously circulates blood flow without beating.
Research scientists began work to develop artificial hearts in the mid-1940s. But despite six decades of development in medical science, no perfect artificial heart has been produced.
If you want to know the reasons for that, repeat clenching and opening your hand. It seems easy. But how long can you do it? One hour or two hours?
Human hearts never stop -- they beat an average of 35 million times per year and do not stop until the moment of death.
A state-of-the-art metal and plastic heart, on the other hand, works for only 18 months because of abrasion of components.
Continuous flow is the key to the development of perfect artificial hearts.
Artificial devices that have been developed so far, including the world’s first one invented in 1982, were called ventricular assist devices (VADs).
Patients can use them until they undergo heart transplant surgery. Users have to live with a VAD for 24 hours a day even though the device, which is as big as a ramyeon box, generates a loud noise.
Doctors at the Texas Heart Institute in the United States changed their way of thinking. Their solution was not to imitate the human heart.
According to reports, they implanted the world’s first beat-less heart into a living human being.
Craig Lewis, a 55-year-old Texas man, lived for five weeks without a pulse, the Daily Mail reported. He died due to an underlying disease -- but doctors said the heart worked perfectly.
The device is formed by intricately combining two VADs and replacing the entire heart, said the newspaper.
