A prosthetic heart valve includes a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end, the stent including a plurality of struts. A plurality of commissure features is disposed on the stent and coupled to selected ones of the struts, each commissure feature including a body having a proximal end and a distal end, and at least one eyelet in the body. The heart valve further includes a collapsible and expandable valve assembly including a plurality of leaflets. At least one leaflet is connected to the at least one eyelet and to at least one of the selected ones of the struts via a suture pattern.
