1. A method of implanting a prosthetic valve within a heart, the method comprising:
- translumenally advancing a prosthetic valve comprising an inflatable structure to a position proximate a native valve of the heart;
inflating a portion of the inflatable structure that is distal to the native valve; and
inflating a portion of the inflatable structure that is proximal to the native annular valve.

Abstract
A method of implanting a prosthetic valve within a heart comprises translumenally advancing a prosthetic valve comprising an inflatable structure to a position proximate a native valve of the heart. A portion of the inflatable structure that is distal to the native valve is inflated. A portion of the inflatable structure that is proximal to the native annular valve is inflated.

4. A method of treating a patient, comprising
translumenally advancing a prosthetic valve a position proximate a native valve of the heart; - and
fully deploying the prosthetic valve at the cardiovascular site;
testing a performance characteristic of the prosthetic valve;
at least partially reversing the deployment of the prosthetic valve;
repositioning the prosthetic valve; and
re-deploying the prosthetic valve.

5. A method of treating a patient, comprising
advancing deployment catheter to a position proximate a native valve of the heart, the deployment catheter comprising an inflation tube and a prosthetic valve comprising an inflatable structure in communication with the inflation tube; -
inflating the inflatable structure with the inflation tube;
removing the deployment catheter from the patient while the inflation tube remains coupled to the inflatable catheter;
advancing a removal catheter over the inflation tube;
deflating the inflatable structure;
retracting the prosthetic valve into the removal catheter; and
withdrawing the prosthetic valve and the removal catheter from the patient.

6. A method of treating a patient, comprising
advancing deployment catheter to a position proximate a native valve of the heart, the deployment catheter comprising a prosthetic valve and a linking member coupled to the prosthetic valve; -
deploying the prosthetic valve;
removing the deployment catheter from the patient while linking member remains coupled to the prosthetic valve;
advancing a removal catheter over the linking member;
retracting the prosthetic valve into the removal catheter; and
withdrawing the prosthetic valve and the removal catheter from the patient.

7. A method of treating a patient, comprising the steps of:
-
identifying a patient with a minimum cross-minimum flow area through an aortic valve of no greater than 0.75 square cm;
enlarging the minimum cross-minimum flow area through the valve; and
deploying a prosthetic valve which provides a minimum cross-sectional flow area of ate least about 1.75 square cm.
