Abstract
A method for heart valve replacement comprises forming an incision in a wall of a ventricle of a heart and inserting a delivery apparatus and a prosthetic heart valve through the incision and into the ventricle of the heart. The prosthetic valve comprises a self-expanding frame having an annular main body and a valve member disposed within the annular main body. The prosthetic valve further comprises an atrial sealing member formed by an annular metal ring and a fabric, wherein only the fabric of the atrial sealing member is connected to the main body for enhancing the flexibility and conformability of the atrial sealing member. The method further comprises deploying the prosthetic valve from the delivery apparatus such that the atrial sealing member extends radially outwardly from the main body within an atrium of the heart and the main body self-expands to a deployed state within a native heart valve.
