Abstract: The invention relates to a prosthetic valve (1) for regulating fluid flow between an upstream side (4) and a downstream side (5) and being operable between an open status and a closed status. The prosthetic valve comprises: —an orifice (2) arranged in a surrounding member (3) and extending between the upstream side (4) and the downstream side (5) wherein in the open status of the prosthetic valve (1) the fluid flow through the orifice is maximally enabled and wherein in the closed status of the prosthetic valve the fluid flow through the orifice in a restriction direction (21) from the downstream side (5) to the upstream side (4) is restricted; and—a leaflet (6) arranged in the orifice and being operable between an open status corresponding to the open status of the prosthetic valve and a closed status corresponding to the closed status of the prosthetic valve. The prosthetic valve further comprises regurgitation means (8, 15, 115, 22) arranged in the prosthetic valve for achieving regurgitation in the restriction direction and arranged for becoming ineffective after a period of deployment.
