An implantable prosthetic valve, comprising: a radially collapsible and expandable annular frame; a leaflet assembly positioned within the frame, the leaflet assembly comprising a plurality of leaflets that are connected to each other to form commissures of the leaflet assembly; wherein the frame comprises a pair of vertical struts (404, 406) adjacent each of the commissures, the struts of each pair being spaced apart from each other so as to define an opening therebetween; wherein at each commissure, two adjacent leaflets (106a, 106b) are positioned between an adjacent pair of vertical struts (404, 406), with one of the leaflets wrapping around at least a portion of one of the vertical struts at a location outside of the frame and the other leaflet wrapping around at least a portion of the other vertical strut at a location outside of the frame; and wherein a cloth portion is positioned radially outward of the frame at each pair of vertical struts and positioned over portions (408, 410) of the leaflets (106a, 106b) that extend radially outside of the frame, the cloth portions being sutured to the leaflet portions (408, 410) that are radially outside of the frame, wherein the cloth portion of each commissure comprises a first cloth portion and each commissure further comprises second and third cloth portions, the second cloth portion wrapping around one of the vertical struts (404, 406) and the third cloth portion wrapping around the other vertical strut (404, 406), each of the second and third cloth portions being sutured to the first cloth portion and one of the leaflet portions (408, 410) that are radially outside of the frame, characterized in that the leaflet assembly is attached to the frame such that the leaflets (106a, 106b) are not directly sutured to the vertical struts (404, 406). a radially collapsible and expandable annular frame; a leaflet assembly positioned within the frame, the leaflet assembly comprising a plurality of leaflets that are connected to each other to form commissures of the leaflet assembly; wherein the frame comprises a pair of vertical struts (404, 406) adjacent each of the commissures, the struts of each pair being spaced apart from each other so as to define an opening therebetween; wherein at each commissure, two adjacent leaflets (106a, 106b) are positioned between an adjacent pair of vertical struts (404, 406), with one of the leaflets wrapping around at least a portion of one of the vertical struts at a location outside of the frame and the other leaflet wrapping around at least a portion of the other vertical strut at a location outside of the frame; and wherein a cloth portion is positioned radially outward of the frame at each pair of vertical struts and positioned over portions (408, 410) of the leaflets (106a, 106b) that extend radially outside of the frame, the cloth portions being sutured to the leaflet portions (408, 410) that are radially outside of the frame, wherein the cloth portion of each commissure comprises a first cloth portion and each commissure further comprises second and third cloth portions, the second cloth portion wrapping around one of the vertical struts (404, 406) and the third cloth portion wrapping around the other vertical strut (404, 406), each of the second and third cloth portions being sutured to the first cloth portion and one of the leaflet portions (408, 410) that are radially outside of the frame, characterized in that the leaflet assembly is attached to the frame such that the leaflets (106a, 106b) are not directly sutured to the vertical struts (404, 406).
