The at least one commissure includes a commissure attachment assembly including a support member disposed at least partially around the commissure tab portions and the commissure tab portions are folded around the support member. The commissure attachment assembly is secured to a first post member of the plurality of post members such that the commissure tab portions are positioned between the first post member and the support member.
