Abstract
A prosthetic valve assembly for implantation in a patient's circulatory system includes a stent, a valve member coupled to the stent and defining a preferred landing zone relative to anatomical structures in the patient's circulatory system, and at least one marker positioned in a predetermined relationship relative to the landing zone of the valve member, the marker being visually distinguishable from the stent using an imaging technique. By observing the marker, the prosthetic valve assembly may be implanted in the patient so that certain ones of the anatomical structures lie within the landing zone.
