1. An implant for improving coaptation of an atrioventricular valve in a human heart, the atrioventricular valve having a first and a second native leaflet, an anterolateral and posteromedial commissure between the first and the second native leaflet, and an annulus adjacent a wall of an atrium of the heart, the implant comprising:
a frame that comprises a middle frame section that frames and supports an artificial central leaflet, the artificial central leaflet being arranged and configured to cover a middle region of the first native leaflet; and
anchor means configured to one of engage with and penetrate the anterolateral and posteromedial commissure;
wherein the middle frame section comprises a bent region, in which a bend is formed between a first region of the artificial central leaflet and a second region of the artificial central leaflet that forms a coaptation plane for coaptation with the second native leaflet, the frame further comprising two side frame sections extending at opposite sides of the middle frame section and arranged and configured to contact side regions of the first native leaflet; and
wherein the frame further comprises at least one clamping frame section, which extends from a distal end of the middle frame section and is arranged and configured to extend on a backside of the first native leaflet and to clamp one of the first native leaflet and the annulus between a clamping end of the at least one clamping frame section and the middle frame section.
