Bio-engineering approach towards making a living heart valve

Qatar University researchers have made advancement in creating living heart valves that can grow after implantation in the human heart. The bioengineering cardiac valves were developed using a mix of nanotechnology, 3D printing, and tissue engineering. The valves shall be inserted into the body where they continue to grow until the valve is fully integrated with the native tissues of the patient. The process showed that the tissue-engineered heart valves imitate the functions of natural heart valves, effectively opening and closing at speeds and pressures close to those available commercially. The researchers plan to test the valves in living animals under different conditions to determine whether they are safe for humans to examine.
