Disclosed are methods and devices for determining valve leaflet orientation. A catheter is provided with a conformable, radiopaque target. The target is deployed within a valve, such as the mitral valve. The conformable target conforms to the coaptation axis in response to closing of the valve leaflets. That coaptation axis may then be visualized, and utilized to determine information about valve operation, or to assist in placement of devices in the vicinity of the valve.
