1. A prosthetic heart valve comprising:
a radially-collapsible annular frame having an inflow end and an outflow end and defining an axial direction between the inflow and outflow ends, the frame comprising three circumferentially spaced apart commissure attachment portions, wherein each commissure attachment portion comprises a first outer strut, a second outer strut, and an inner strut between the first and second outer struts, wherein the first outer strut, the second outer strut, and the inner strut extend in the axial direction; and
a valve structure positioned within the frame comprising three leaflets, with each leaflet having two opposing leaflet tabs, wherein adjacent pairs of the leaflet tabs join to form three commissures of the valve structure, and the three commissures are secured to the three commissure attachment portions of the frame such that the valve structure is configured to open during systole and close during diastole when the prosthetic heart valve is implanted in a patient,
wherein at each commissure, a first leaflet tab of one of the leaflets and a second leaflet tab of another one of the leaflets are both secured to one of the commissure attachment portions of the frame via the first outer strut, the second outer strut, and the inner strut, and
wherein at each commissure, the first leaflet tab extends radially between the first outer strut and the inner strut, and the second leaflet tab extends radially between the second outer strut and the inner strut.
