摘要：
Apparatus and methods are described herein for use in the delivery of a prosthetic mitral valve. In some embodiments, an apparatus includes an epicardial pad configured to engage an outside surface of a heart to secure a prosthetic heart valve in position within the heart. The epicardial pad defines a lumen configured to receive therethrough a tether extending from the prosthetic valve. The epicardial pad is movable between a first configuration in which the epicardial pad has a first outer perimeter and is configured to be disposed within a lumen of a delivery sheath and a second configuration in which the epicardial pad has a second outer perimeter greater than the first outer perimeter. The epicardial pad can be disposed against the outside surface of the heart when in the second configuration to secure the prosthetic valve and tether in a desired position within the heart.
