1. A prosthetic heart valve comprising:

  • a collapsible and expandable annular frame that is configured to be collapsed to a radially collapsed state for mounting on a delivery apparatus and expanded to a radially expanded state inside a patient'"'"'s body, the frame having an inflow end, an outflow end, and a lumen extending from the inflow end to the outflow end, the frame comprising a plurality of struts defining a plurality of cells;

    a collapsible and expandable valve member mounted within the annular frame;

    a collapsible and expandable annular sealing member coupled to the annular frame, wherein the sealing member is configured to contact and create a seal against tissue surrounding the prosthetic valve once implanted in a patient'"'"'s body; and

    a first suture secured to the annular frame and circumferentially extending across a circumferentially extending row of the cells of the annular frame, wherein the suture extends across a midpoint of each cell in the row of cells;

    a second suture securing the sealing member to the annular frame along an inflow end of the sealing member; and

    a third suture securing the sealing member to the annular frame along an outflow end of the sealing member;

    wherein the first suture is positioned axially between the second suture and the third suture;

    wherein portions of the sealing member extending over the row of cells can expand radially outwardly from the frame;

    wherein the first suture is secured to opposing side struts of each cell in the row of cells;

    wherein the first suture is spaced between an inflow end of the row of cells and an outflow end of the row of cells along a length of the frame;

    wherein the first suture extends continuously around the lumen of the frame; and

    wherein the first suture is positioned to prevent the annular sealing member from protruding into the lumen of the annular frame in the radially expanded state and contacting the valve member.
