a radially collapsible and expandable annular frame comprising a plurality of angled struts and having an outflow end and an inflow end, wherein the angled struts are arranged to form a plurality of circumferentially extending rows of closed cells, including an uppermost row of closed cells defining the outflow end of the frame and a lowermost row of closed cells defining the inflow end of the frame; and
a leaflet structure positioned within the frame, the leaflet structure comprising a plurality of leaflets each comprising two opposing commissure portions, each leaflet having a lower edge portion coupled to the frame and a width that decreases from the commissure portions to a lowermost end of the leaflet, and each commissure portion being paired with an adjacent commissure portion of an adjacent leaflet to form commissures of the leaflet structure;

wherein the frame comprises a plurality of vertical commissure support portions supporting respective commissures of the leaflet structure;
wherein the vertical commissure support portions are positioned axially along the frame entirely within the uppermost row of closed cells;
wherein the uppermost row of closed cells is formed partly by an uppermost, circumferentially extending row of angled struts of the frame interconnecting circumferentially adjacent commissure support portions;
wherein the commissure support portions are circumferentially spaced apart from each other by a plurality of closed cells of the uppermost row of closed cells; and
wherein the collapsed implantable prosthetic valve can be mounted around the balloon and radially expanded to the expanded configuration with the balloon inside a patient's body.
