1. A prosthetic heart valve assembly comprising:

  • a prosthetic valve including a circumferential wall having an inner surface and an outer surface, wherein the prosthetic valve is radially contractible and expandable for transcatheter delivery to a native annulus; and

    two or more sealing members mounted on the prosthetic valve and substantially evenly placed around the prosthetic valve, wherein the sealing members have a size and shape corresponding to gaps existing between the implanted prosthetic valve and the native valve and are configured to engage the gaps to prevent paravalvular leakage;

    wherein the two or more sealing members protrude from the outer surface of the prosthetic valve in both a crimped configuration before the prosthetic valve is implanted and a deployed configuration after the prosthetic valve is implanted; and

    wherein the two or more sealing members do not extend beyond a maximum diameter of the outer surface of the prosthetic valve when the prosthetic valve is in the crimped configuration before the prosthetic valve is implanted.
