1. 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, and a plurality of axial frame members bridging the first row of angled struts and the second row 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 each of the plurality of axial frame members has a first end closer to the outflow end and a second end closer to the inflow end,
wherein the plurality of axial frame members comprises exactly three axially extending leaflet attachment members and exactly three axial struts, wherein the three leaflet attachment members are connected to respective commissures of the leaflet structure, wherein the first end of each leaflet attachment member is located on and attached to the first row of angled struts and the second end of each leaflet attachment member is located on and attached to the second row of angled struts,
wherein the first row of angled struts is the only circumferentially extending row of angled struts linking the first ends of the plurality of axial frame members,
wherein there are at least three circumferentially extending rows of angled struts between the second ends of the plurality of axial frame members and the inflow end,
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.
