Objective To observe the physiochemical properties and calcification resistance of the bovine jugular conduits with valves stabilized by dye-mediated photo-oxidation provide the theoretical basis for clinical application and seek better biological-materical for RVOT reconstruction.Methods Twenty-four bovine jugular conduits with valves were divided into 3 groups and treated with dye-mediated photo-oxidation(Group Ⅰ), glutaraldehyde (Group Ⅱ)and untreated group (Group Ⅲ) respectively. Morphologic and physioc...
