Iranian Professor Makes Most Advanced Artificial Heart

Saturday, May 31, 2008

The first artificial heart of the world which will be planted in human chest has been designed and manufactured by an Iranian professor and researcher. Professor Mousivand, a subspecialist in heart surgery and professor of heart surgery at Ottawa University School of Medicine, is one of the most prominent medical figures of Iran and the world. It took many years before the mechanical heart was produced. It weighs less than 500 grams.

No open surgery is needed to plant the heart and it will prevent blood clot formation while allowing the patient to go on with everyday activities of life after leaving the hospital. Its price is one –tenth of previous mechanical hearts and does not cause infection. These characteristics have differentiated the new heart from its predecessors. It operates on a small 180-gram battery, which is charged from the outside. It is possible to monitor patient’s situation using remote control and even if the patient were at the North Pole, the physicians could check his/her health state at the hospital by taking advantage of a satellite.

Many years have passed since the first mechanical hearts were manufactured. Since that time, many physicians and researchers have worked to produce an artificial heart which would entail a lower risk of infection, hemorrhage, heaviness and so on. Millions of hours of professional work have been spent on this subject.

Artificial hearts were such that they could not be planted inside the chest. One reason was their heaviness; they were at least 100 kg and needed to be attached to outside machines through cables and this caused many problems for the patients. Formation of blood clots with subsequent risk of stroke or heart attack was another risk. Also, patients should have been confined within the hospital because they were attached to the artificial heart which looked like a refrigerator. This rendered them unable to go on with daily activities while increasing the risk of infection in addition to being cumbersome and expensive. Therefore, medical researchers at Ottawa University, Canada, and Cleveland Clinic Hospital decided to design a machine which would be free from the above problems.
