摘要:
A prosthetic cardiac valve comprises an anchor having an atrial skirt, an annular region, and a ventricular skirt. The prosthetic valve also has a plurality of prosthetic valve leaflets each having a first end and a free end. The first end is coupled with the anchor and the free end is opposite the first end. The prosthetic cardiac valve has an open configuration in which the free ends of the prosthetic valve leaflets are disposed away from one another to allow antegrade blood flow therepast, and a closed configuration in which the free ends of the prosthetic valve leaflets engage one another and substantially prevent retrograde blood flow therepast. The anchor has a collapsed configuration for delivery to the heart and an expanded configuration for anchoring the prosthetic cardiac valve to a patient's heart.
