In China, where Rheumatic heart disease is still prevalent, two thirds of valve replacements are in mitral position. Before a valve replacement operation is conducted, most patients have reached Class III/IV heart function under the New York Heart Association (NYHA) classification system. As the background to this disease is quite different to that of degenerated cases, which are more prevalent in Western countries, the development of an artificial heart valve that is suitable for local patients is very significant for China. In this medium long-term clinical follow-up study, a data analysis was conducted of domestic heart valve production for mitral replacement.
