A heart valve (100) consists of a valve stent (110) and a valve leaflet (190). The valve leaflet (190) is accommodated in the valve stent (110). The valve leaflet (190) comprises at least two pieces and is centrally symmetrically distributed along the circumferential direction of the inner surface of the valve stent (110). One end of the two adjacent leaflets (190) is combined on the valve stent (110) to form a valve angle (192). A locator (1147) is arranged on the valve stent (110). The perpendicular line from one angle (192) to the axis of the valve stent (110) coincides with the projection of the perpendicular line from the axis of the positioner (1147) to the axis of the valve stent (110) on the plane perpendicular to the axis of the valve stent (110). The heart valve (100) can reduce the central reflux to a great extent.
