a delivery catheter comprising a balloon; and
an implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration, the implantable prosthetic valve comprising:
a radially collapsible and expandable annular frame having an inflow end and an outflow end;
a leaflet structure positioned within the annular frame and configured to permit blood flow from the inflow end to the outflow end and block blood fluid flow from the outflow end to the inflow end; and
an outer skirt secured to an exterior portion of the annular frame;

wherein the annular frame comprises a first row of angled struts defining the outflow end, a second row of angled struts being closer to the inflow end than the first row of angled struts, and six axial frame members bridging the first and second rows of angled struts,
wherein each axial frame member has a first end closer to the inflow end and a second end closer to the outflow end,
wherein the first row of angled struts is the only row of angled struts linking the second ends of the plurality of axial frame members,
wherein there are exactly four angled struts in the second row of angled struts connecting each two adjacent first ends of the plurality of axial frame members,
