1. A prosthetic valve for implanting at a native mitral or tricuspid valve region of the heart, the prosthetic valve comprising:
a radially compressible and expandable frame comprising an inflow end, an outflow end, and a double-body structure having an annular inner frame and an annular outer frame, the inner frame having a main body comprising a plurality of circumferentially extending rows of angled struts and the annular outer frame having an upper portion proximate the inflow end and configured to contact an atrial face of a native valve annulus;
a plurality of prosthetic leaflets mounted within the inner frame for regulating the flow of blood in one direction through the frame; and
a plurality of ventricular anchors, each comprising a free end portion, an intermediate portion, and a fixed end portion connected to and extending from an intersection of adjacent angled struts in one of the circumferentially extending rows of angled struts of the inner frame, the intermediate portion extending downwardly from the fixed end portion and then curving upwardly in a direction toward the inflow end such that each ventricular anchor is configured to extend behind and engage native valve leaflets in a ventricle of the heart, wherein the fixed end portion of each ventricular anchor is connected to and extends from the intersection of adjacent angled struts that forms a node spaced from an outflow end of the main body of the inner frame.
