Transcatheter aortic valve repair and replacement
A heart valve assembly includes an outer frame. The outer frame is formed from a metallic material and defines a gridded configuration. An inner frame houses a prosthetic heart valve. The inner frame is a graft covering extending around the prosthetic heart valve for providing sealing to the heart valve. The graft covering is one of polyester, PTFE, ePTFE, or a polymer. The outer frame is secured to the graft covering. The outer frame is secured to the graft covering by a plurality of stitches. A plurality of radially extending fibers extend from the graft covering and through the outer metallic frame to form a seal positioned outwardly of the outer frame. The fibers include strands of fibers that terminate in an end thereof outwardly of the outer frame.
