A prosthetic valve for implanting at a native heart valve region of the heart, the heart valve having a native annulus and native valve leaflets extending downward from the annulus into a ventricle, the prosthetic valve comprising: a main body (1222, 1322) comprising a lumen and configured for placement within the native annulus, the main body (1222, 1322) being radially compressible to a radially compressed state for delivery into the heart and self-expandable from the compressed state to a radially expanded state; and a valve structure coupled to the inner surface of the main body (1222, 1322), the valve structure comprising a plurality of valve leaflets that form a one-way valve in the lumen; at least two ventricular anchors (1226, 1326) extending from a ventricular end (1230, 1330) of the main body (1222, 1322) and disposed outside of the main body for securing the prosthetic valve to the native valve leaflets, wherein the ventricular anchors (1226, 1326) are configured to capture the heart valve leaflets between the ventricular anchors (1226, 1326) and an outer surface of the main body (1222, 1322); characterised in that each ventricular anchor (1226, 1326) is finger-like and extends from at least one attachment point on the ventricular end (1230, 1330) of the main body (1222, 1322) and wherein each ventricular anchor (1226, 1326) is pre-formed to extend along the outer surface of the main body (1222, 1322) in the functional deployed state, and wherein each ventricular anchor (1226, 1326) is configured to be partially or completely straightened in a ventricular direction and retained in a sheath of a delivery device and to spring back to the pre-formed shape for capturing the native leaflets when advanced from the sheath. a main body (1222, 1322) comprising a lumen and configured for placement within the native annulus, the main body (1222, 1322) being radially compressible to a radially compressed state for delivery into the heart and self-expandable from the compressed state to a radially expanded state; and a valve structure coupled to the inner surface of the main body (1222, 1322), the valve structure comprising a plurality of valve leaflets that form a one-way valve in the lumen; at least two ventricular anchors (1226, 1326) extending from a ventricular end (1230, 1330) of the main body (1222, 1322) and disposed outside of the main body for securing the prosthetic valve to the native valve leaflets, wherein the ventricular anchors (1226, 1326) are configured to capture the heart valve leaflets between the ventricular anchors (1226, 1326) and an outer surface of the main body (1222, 1322); characterised in that each ventricular anchor (1226, 1326) is finger-like and extends from at least one attachment point on the ventricular end (1230, 1330) of the main body (1222, 1322) and wherein each ventricular anchor (1226, 1326) is pre-formed to extend along the outer surface of the main body (1222, 1322) in the functional deployed state, and wherein each ventricular anchor (1226, 1326) is configured to be partially or completely straightened in a ventricular direction and retained in a sheath of a delivery device and to spring back to the pre-formed shape for capturing the native leaflets when advanced from the sheath.
