1. A prosthetic heart valve comprising:
a frame comprising an inflow end and an outflow end and being movable from a radially collapsed configuration to a radially expanded configuration, wherein the frame comprises:
a plurality of struts disposed between the inflow end and the outflow end;
a first plurality of apices disposed at the inflow end and formed by intersections of two or more struts of the plurality of the struts;
a second plurality of apices disposed at the outflow end;
a plurality of junctions disposed between the first plurality of apices and the outflow end and circumferentially aligned with the plurality of second apices, wherein:
each junction of the plurality of junctions is formed by intersections of two or more struts of the plurality the struts, and
the plurality of junctions is circumferentially offset relative to the first plurality of apices;
a valvular structure positioned within and secured to the frame, wherein the valvular structure comprises a plurality of leaflets movable between an open configuration and a closed configuration, wherein in the open configuration blood flow is permitted from the inflow end to the outflow end, and wherein in the closed configuration blood flow is restricted from the outflow end to the inflow end; and
a skirt positioned around an outer surface of the frame, wherein the skirt comprises:
a first edge portion secured to the frame at a plurality of first circumferential attachment points of the frame, wherein the plurality of first circumferential attachment points is disposed at the first plurality of apices; and
a second edge portion secured to the frame at a plurality of second circumferential attachment points of the frame, wherein the plurality of second circumferential attachment points is disposed at the plurality of junctions,
wherein the plurality of first circumferential attachment points is circumferentially offset and spaced longitudinally relative to the plurality of second circumferential attachment points.
