1. A delivery system for percutaneously delivering a self-expanding valve prosthesis comprising:

  • an elongated shaft component;

    a self-expanding valve prosthesis disposed over a distal portion of the elongated shaft component, wherein the valve prosthesis has a compressed configuration for delivery within a vasculature and an expanded configuration for deployment;

    at least one cinching suture for coupling the valve prosthesis to the elongated shaft component, wherein the at least one cinching suture is removable and radially compresses the valve prosthesis into the compressed configuration for delivery; and

    a radially-expandable sleeve secured to and encircling an outer surface of the valve prosthesis, wherein the radially-expandable sleeve is configured to transform from a delivery state in which the radially-expandable sleeve has a first diameter and extends over a full length of the valve prosthesis in the compressed configuration to a deployed state in which the radially-expandable sleeve has a second diameter greater than the first diameter and extends over a portion of the valve prosthesis in the expanded configuration, the portion being less than the full length of the valve prosthesis, the radially-expandable sleeve being configured to prevent paravalvular leakage in situ in the deployed state.
