The journey toward developing an artificial heart has been lengthy and difficult, but progress has been made. In 1982, the first successful implantation of an artificial heart took place. However, it was only designed as a temporary measure until the patient could receive a heart transplant. It wasn’t until 2001 that the first self-contained artificial heart was implanted. Although the patient only lived 151 days after the surgery, scientists are committed to perfecting the technology. The potential of artificial hearts is enormous. They can not only serve as a replacement for human hearts, but they can also act as a bridge to transplant for those who are waiting for a donor’s heart.
In conclusion, while the development of artificial hearts has been a challenging journey, with each passing year, we are getting closer to finding a reliable solution for those suffering from heart disease.
