1. A method for implanting a prosthetic valve in a heart of a patient, comprising:
advancing a delivery catheter to a position between native valve leaflets of a native mitral or tricuspid valve,
the delivery catheter containing a radially self-expandable tubular body, the tubular body extending in an axial direction from an inflow end to an outflow end, and including a lumen in which the prosthetic valve is disposed, and a fabric attached the tubular body so as to cover a part of an outer surface of the tubular body;
partially deploying the tubular body from the delivery catheter such that an outflow end portion of the tubular body is deployed from the delivery catheter while an inflow end portion of tubular body remains in a radially compressed state inside a lumen of the delivery catheter, the outflow end portion being deployed at a position distal of a distal edge of at least one of the native valve leaflets;
moving the delivery catheter in a proximal direction towards an atrial chamber of the heart such that the outflow end portion of the partially deployed tubular body engages the distal edge of the at least one native valve leaflet and lifts the at least one native valve leaflet in the proximal direction towards the atrial chamber of the heart; and
then deploying the inflow end portion of the tubular body such that the tubular body is fully deployed and the at least one native valve leaflet is captured between the outflow end portion and the inflow end portion of the tubular body.
