    Decellularized tricuspid biological heart valve. Biological scaffolds can be created from human donor tissue or from animals; however, animal tissue is often more popular since it is more widely accessible and more plentiful. [10] Xenograft, from a donor of a different species from the recipient, heart valves can be from either pigs, cows, or ...

    en.wikipedia.org/wiki/Artificial_heart_valve

    An artificial heart valve is a one-way valve implanted into a person's heart to replace a heart valve that is not functioning properly (valvular heart disease).Artificial heart valves can be separated into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.

    The use of hECTs in generating tissue engineered heart valves is also being explored to improve current heart valve constructs for in vivo animal studies. [20] As tissue engineering technology advances to overcome current limitations, hECTs are a promising avenue for experimental drug discovery, screening and disease modelling and in vivo repair.

    Prosthetic heart valves, including the Hancock Aortic Tissue Valve, are not without drawbacks. Structural degradation is a risk, potentially necessitating reoperation. [ 13 ] [ 3 ] Studies have indicated the need for ongoing research and improvement in bioprosthetic valve technology to address such concerns [ 13 ]

    St. Jude Medical was founded in 1976 to further develop bi-leaflet artificial heart valves, which were originally created in 1972 at the University of Minnesota. [4] [5] St. Jude Medical's bi-leaflet valve was developed in large part by Dr. Demetre Nicoloff of the University of Minnesota and St. Jude Medical employee Don Hanson.

  9. Heart valve - Wikipedia

    en.wikipedia.org/wiki/Heart_valve

    A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine the direction of blood flow through the heart. Heart valves are opened or closed by a difference in blood pressure on each side. [1] [2] [3]
