1. A method of deploying a prosthetic heart valve, comprising:

  • advancing a catheter shaft into a patient'"'"'s body, the catheter shaft having a deployment mechanism and a prosthetic heart valve disposed along a distal end portion thereof, the prosthetic heart valve comprising an expandable stent body and a plurality of leaflet-forming membranes, the prosthetic heart valve releasably coupled to the deployment mechanism;

    expanding the prosthetic heart valve from a fully contracted configuration to an initial expanded configuration and into contact with surrounding tissue at an implantation site in the patient'"'"'s body;

    contracting the prosthetic heart valve from the initial expanded configuration to a partially contracted configuration by actuating the deployment mechanism;

    modifying a position of the prosthetic heart valve relative to the implantation site; and

    expanding the prosthetic heart valve from the partially contracted configuration to a fully expanded configuration by actuating the deployment mechanism;

    wherein the stent body has an outer diameter in the fully expanded configuration that is greater than an outer diameter in the initial expanded configuration.
