1. A prosthetic heart valve assembly comprising:
an annular inner frame comprising a plurality of interconnected struts that form a plurality of rows of cells including an inflow row of cells and an outflow row of cells;
a prosthetic leaflet section disposed within the inner frame between the inflow row of cells and the outflow row of cells; and
an annular outer support stent coupled to the inner frame, the outer support stent comprising one or more leaflet capturing arms, wherein the inner frame is disposed within the outer support stent;
wherein the leaflet capturing arms are sized and shaped to capture native leaflets between the leaflet capturing arms and a portion of the prosthetic heart valve; and
wherein each of the leaflet capturing arms comprises a downstream portion that is oriented toward the outflow end portion of the prosthetic heart valve assembly, an upstream portion that is oriented toward an inflow end portion of the prosthetic heart valve assembly, and an intermediate portion extending from the downstream portion to the upstream portion, wherein each of the leaflet capturing arms is shape set such that, when the prosthetic heart valve assembly is in a radially expanded state, the intermediate portion bends relative to the downstream portion at a first inflection point to define a concave region along an outer surface of the leaflet capturing arm and the upstream portion bends relative to the intermediate portion at a second inflection point to define a convex region along the outer surface of the leaflet capturing arm.
