A study carried out by a researcher from Tel Aviv University aims to help artificial heart patients avoid heart valve replacement. The researchers explained that the artificial heart operations are either with a mechanical heart that lasts for a long time, but requires supervision and daily care of anticoagulants, or a vital heart valve made of animal tissues, which helps the patient to live a normal life for a specific period, but its biggest problem is that it decomposes after 10 years, which requires replacing it with new tissues.

Therefore, researchers have genetically engineered a heart valve from animal tissues, and what distinguishes this valve is that it does not decompose in the human body as a result and reduces the immune system's resistance to the artificial valve, which leads to a qualitative leap in the world of prosthetic heart valves.
