Claim 5:
6. An assembly, comprising:
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:
an annular frame comprising:
an inflow end;
an outflow end;
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;
a third row of angled struts being closer to the inflow end than the second row of angled struts; and
a plurality of axial frame members bridging the first and second rows of angled struts; and

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,

wherein the plurality of axial frame members have respective first ends and second ends, the first ends being linked by the first row of angled struts and the second ends being linked by the second row of angled struts,
wherein the plurality of axial frame members comprise a plurality of axially extending commissure supports connected to respective commissures of the leaflet structure and exactly one axial strut located between any two immediately adjacent commissure supports,
wherein a plurality of angled struts in the first row connect each commissure support and an immediately adjacent axial strut in a circumferential direction,
wherein there are at least three angled struts in the second row between any two immediately adjacent axial frame members in the circumferential direction;
wherein the plurality of axial frame members terminate at the second row of angled struts,
wherein the second row of angled struts is the closest row of angled struts to the first row of angled struts,
wherein the prosthetic valve in the collapsed configuration can be mounted around the balloon and radially expanded to the expanded configuration with the balloon inside a patient's body.
