Abstract: A prosthetic mitral valve with improved blood flow to the left ventricular outflow tract (LVOT). The prosthetic mitral valve includes an expandable outer stent having an atrial end and a ventricular end, and an expandable inner stent attached to and at least partially positioned within the outer stent. The inner stent has an inflow end, an outflow end and a connector securing a tether. A valve assembly including a cuff and a plurality of leaflets may be disposed within the inner stent. The outer stent is expandable from a delivery condition in which the outer stent is axially elongated to a deployed condition in which a first portion of the outer stent is folded upon a second portion of the outer stent to define a flange for engaging an atrial surface of a native valve annulus and to stabilize the prosthetic heart valve within the native valve annulus.

Abstract: An epicardial anchor device may include a base and a hub each defining a radial slot. The hub is received within, and is rotatable relative to, the base. The radial slot of the hub defines a tether passageway for receiving a tether coupled to a prosthetic heart valve. The epicardial anchor device may have an unlocked configuration in which the radial slot of the base aligns with the radial slot of the hub so that the tether may be slid laterally through the radial slot of the base, and a locked configuration in which the radial slot of the base is out of alignment with the radial slot of the hub so that the tether cannot be slid laterally away from the radial center of the hub. Rotation of the hub may transition the epicardial anchor device from the locked to the unlocked configuration.

Abstract: Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when the valve is in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The distal end portion of the delivery sheath is inserted into a left atrium of a heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. In some embodiments, actuation wires are used to assist in the reversion of the outer frame. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.
