1. A method of delivering to the mitral valve annulus of a heart a prosthetic mitral valve having a valve body expandable from a collapsed, delivery configuration to an expanded, deployed configuration, and having at least one anchoring tether extending from a ventricular end of the valve body, and having an atrial cuff extending from the atrial end of the valve body, the method comprising:
- delivering the prosthetic heart valve to the left atrium of the heart;
anchoring a ventricle portion of the anchoring tether to a wall of the ventricle of the heart;
causing the valve body to move from the delivery configuration to the deployed configuration, with the valve body disposed in the mitral valve annulus and with the atrial cuff engaging the atrial side of the mitral valve annulus;
urging the atrial cuff against the native valve annulus; and
fastening the anchoring tether to the valve body.

9. A method of delivering to the mitral valve annulus of a heart a prosthetic mitral valve including a valve body and having a collapsed, delivery configuration and an expanded, deployed configuration, and at least one anchoring tether extending from the stent body, the method comprising:
-
inserting a delivering device into the left atrium of the heart, the delivery device including a delivery sheath defining a lumen and the prosthetic mitral valve being disposed within the lumen in the collapsed, delivery configuration; inserting the delivery device through the mitral annulus, through a wall of the ventricle, anchoring a portion of the anchoring tether to the wall of the ventricle of the heart; moving the delivery device back through the mitral annulus and within the atrium such that the valve body is moved to the expanded, deployed configuration, and is disposed in the mitral valve annulus; urging at least a portion of the valve body against the mitral valve annulus. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of delivering to the mitral valve annulus of a heart a prosthetic mitral valve including a valve body and having a collapsed, delivery configuration and an expanded, deployed configuration, and at least one anchoring tether extending from the stent body, the method comprising:
-
accessing the left ventricle of the heart with a delivering device, the delivery device including a delivery sheath defining a lumen and the prosthetic mitral valve being disposed within the lumen in the collapsed, delivery configuration; anchoring a portion of the anchoring tether to a first side of a wall of the ventricle of the heart with a first tether anchor device; anchoring a portion of the anchoring tether to a second opposite side of the wall of the ventricle of the heart with a second tether anchor device; deploying the valve body within the atrium of the heart such that the valve body is moved to the expanded, deployed configuration, and is disposed in the mitral valve annulus. - View Dependent Claims (16, 17, 18, 19, 20)
