1. A transcatheter valve prosthesis comprising:

  • a stent having a compressed configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve;

    a prosthetic valve component disposed within and secured to the stent; and

    an anti-paravalvular leakage component coupled to and encircling an outer surface of the tubular stent, the anti-paravalvular leakage component including a plurality of self-expanding segments and an annular sealing element attached to the segments, a first end and a second end of each segment being attached to the outer surface of the tubular stent at first and second attachment points, respectively, wherein the anti-paravalvular leakage component has an expanded configuration in which the segments curve radially away from the outer surface of the tubular stent and are oblique to the outer surface of the tubular stent such that a plane defined by each segment is non-perpendicular with respect to a tangential plane of the tubular stent taken through the first and second attachments points.
