1. A prosthetic heart valve, comprising:
an annular frame including a plurality of interconnected strut members, the frame being radially collapsible to a collapsed configuration and radially expandable to an expanded configuration;
a plurality of leaflets situated within the frame, each leaflet comprising opposing commissure tab portions on opposite sides of the leaflet, each commissure tab portion being paired with an adjacent commissure tab portion of an adjacent leaflet to form at least one commissure;
a plurality of post members mounted on an interior surface of the frame;
wherein the at least one commissure comprises a commissure attachment assembly, the commissure attachment assembly comprising a support member, the support member comprising a central opening disposed at least partially around the commissure tab portions such that the commissure tab portions extend through the central opening of the support member;
wherein the commissure tab portions of the commissure attachment assembly are folded around the support member and away from each other; and
wherein the commissure attachment assembly is secured to a first post member of the plurality of post members such that the support member is aligned in the radial direction with the first post member and the commissure tab portions are positioned between, in the radial direction, the first post member and the support member, wherein the radial direction is relative to a central longitudinal axis of the frame.
