Abstract
Abstract The present invention relates to the correction of mitral and tricuspid valve regurgitation. More particularly this means that he leaflet bases of the posterior and anterior mitral leaflets are connected to each other with a stabilizing element ( 14 ) extended transversely across the valve annulus ( 13 ). Said stabilizing element ( 14 ) is by first ( 22 ) and second ( 24 ) ends secured into a first ( 26 ) and a second ( 28 ) position respectively at said valve annulus ( 13 ) by means of sutures, anchors or clips. Coaptation is attained, by reducing the length of the stabilizing element ( 14 ) from D 1 to D 2.
