1. A transcatheter valve prosthesis comprising:
a frame having a proximal end, a distal end and a plurality of openings, each opening of the plurality of openings being formed by a plurality of struts of the frame, the frame 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 frame; and
an outer component coupled to and encircling the frame, the outer component including a plurality of self-expanding segments and a sealing element attached to the plurality of self-expanding segments,
wherein each self-expanding segment has a first end and a second end, the first end being attached directly to a first strut of the plurality of struts of the frame at a first attachment point and the second end being attached directly to a second strut of the plurality of struts of the frame at a second attachment point, the first strut forming a portion of a first opening of the plurality of openings and the second strut forming a portion of a second opening of the plurality of openings, the first and second openings being adjacent to each other,
wherein the outer component has an expanded configuration in which an entire length of each self-expanding segment extends radially away from, and is oblique to, an outer surface of the frame, such that a plane defined by each self-expanding segment is non-perpendicular with respect to a tangential plane taken through its respective first and second attachment points.
