Claim 11:
12. 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;
a fourth row of angled struts being closer to the inflow end than the third row of angled struts; and
exactly six 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 there are exactly four angled struts in the second row of angled struts connecting each two adjacent second ends of the plurality of axial frame members,
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,
wherein the first row of angled struts, the second row of angled struts, and the plurality of axial frame members define a row of first cells of the frame, wherein the second row of angled struts and the third row of angled struts define a row of second cells of the frame, wherein the first cells are larger than the second cells,
wherein the third row of angled struts and the fourth row of angled struts define a row of third cells of the frame, wherein the second cells are the same size as the third cells.
