Transcatheter valve prosthesis and method for implanting the same

A method for implanting a prosthetic valve in a heart of a patient, comprising:

• advancing a delivery catheter to a native mitral or tricuspid valve,
• the delivery catheter containing a 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;
• 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 the tubular body remains inside a lumen of the delivery catheter, the outflow end portion being deployed at a position distal of a junction between a leaflet part and chordae attached to the leaflet part of at least one native valve leaflet of the native mitral or tricuspid valve;
• 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 at least one native valve leaflet;
• and
• then deploying the inflow end portion of the tubular body such that the tubular body is fully deployed.
