Abstract: Atrio-ventricular valve stent (1) having a tubular shape, with a sub annular anterior side (2), a sub annular posterior side (3) and sub annular lateral sides (13), the sub annular anterior side (2) comprising a self-folding native leaflet engagement member (4-9) that forms a straight extension of said sub annular anterior side (2) when the stent (1) is collapsed and that is folded on itself when the stent (1) is in an expanded state; said engagement member (4-9) forming an integral part of the stent (1) and wherein each sub annular lateral side (13) is longer than said sub annular anterior side (2) when the stent (1) is in an expanded state.

Abstract: A prosthetic valve, preferably an expandable prosthetic valve, having a valve component (3), preferably a mitral valve component, made of a single functional leaflet (6) wherein the prosthetic valve (1) comprises at least two tissue supports (4?, 4?,4??,4??) attachable to an inner surface (5) of a stent component (2), wherein at least one tissue support (4?, 4?,4??,4??) comprises at least one attachment area (7?, 7?), at least a section of the attachment area extending essentially inwardly from the inner surface (5), wherein said leaflet (6) is attached to at least one tissue support (4?, 4?,4??,4??) at the section of said attachment area(s) (7?, 7?) such that the leaflet (6) is arranged between said attachment area(s) (7?,7?) or integrally formed with one tissue support (4?,4?,4??,4??) and attached to the second tissue support (4?,4?,4??,4??) at the section of the attachment area(s) (7?,7?).
