1. An assembly comprising:
a delivery catheter comprising a handle, a shaft extending from the handle, and an inflatable balloon coupled to the shaft, wherein the shaft comprises a conduit for conducting inflation fluid to and from the balloon; and
an implantable prosthetic heart valve that is radially collapsible to a collapsed configuration for delivery into a patient on the delivery catheter, and radially expandable to an expanded configuration using the balloon;
the prosthetic heart valve comprising:
a radially collapsible and expandable annular frame having an inflow end portion defining an inflow end of the frame that is configured to receive antegrade blood flow into the prosthetic heart valve when implanted within the patient's body in the expanded configuration, and an outflow end portion defining an outflow end of the frame opposite the inflow end of the frame; and
a valve structure positioned within the frame and secured to the frame, the valve structure configured to restrict retrograde blood flow from the outflow end toward the inflow end;
wherein the frame comprises an inflow end row of cells along the inflow end and an outflow end row of cells along the outflow end portion, wherein the outflow end row of cells extends continuously around the frame, wherein the cells of the outflow end row of cells are larger than the cells of the inflow end row of cell;
wherein the inflow end row of cells comprises exactly 12 cells and the outflow end row of cells comprises exactly 6 cells; and
wherein the frame comprises exactly 12 apices at inflow ends of the 12 cells of the inflow end row of cells, and exactly 6 apices at outflow ends of the 6 cells of the outflow end row of cells;
wherein the prosthetic heart valve in the collapsed configuration can be mounted around the balloon and radially expanded to the expanded configuration with the balloon inside the patient's body.
