1. A prosthetic heart valve comprising:
an annular frame that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration, the frame having a plurality of circumferentially extending rows of angled struts, including a first row of angled struts defining an inflow end of the frame, a second row of angled struts downstream of the first row, a third row of angled struts downstream of the second row, a fourth row of angled struts downstream of the third row, and a fifth row of angled struts downstream of the fourth row, each row of angled struts comprising angled struts arranged in a zig-zag pattern;
a leaflet structure comprising three leaflets forming three commissures of the leaflet structure, wherein the commissures are connected to the frame; and
an annular outer sealing member extending around an outer surface of the frame, the sealing member having an inflow edge portion secured to the struts of the first row with sutures and an outflow edge portion having a plurality of tapered projections secured with sutures to the struts of a selected one of the second, third, or fourth row of angled struts, wherein the projections are shaped to correspond to the zig-zag pattern of the selected row of struts;
wherein the outer sealing member is configured to stretch axially when the frame is radially compressed to the collapsed configuration;
wherein the outer sealing member comprises a fabric comprising an inner mesh layer and an outer pile layer, wherein the mesh layer comprises a plurality of circumferentially extending first rows of interlaced yarns alternating with a plurality of circumferentially extending second rows of interlaced yarns, wherein the first rows have a density greater than the second rows, and wherein the pile layer is formed from yarns extending from and interlaced with the mesh layer.
