Abstract
A prosthetic heart valve includes a valve frame defining an aperture that extends along a central axis and a flow control component mounted within the aperture. The valve frame includes a distal anchoring element and a proximal anchoring element. The valve frame has a compressed configuration to allow the prosthetic heart valve to be delivered to a heart of a patient via a delivery catheter. The valve frame is configured to transition to an expanded configuration when released from the delivery catheter. The prosthetic heart valve is configured to be seated in a native annulus when the valve frame is in the expanded configuration. The distal and proximal anchoring elements configured to be inserted through the native annulus prior to seating the prosthetic heart valve. The proximal anchoring element is ready to be deployed subannularly or is optionally configured to be transitioned from a first configuration to a second configuration after the prosthetic valve is seated.
