摘要：
A prosthetic valve assembly (820) for use in replacing a deficient native valve comprises a replacement valve supported on an expandable prosthesis frame (822) . The prosthesis frame has a non-cylindrical configuration with a preset maximum expansion diameter region about the valve opening to maintain the preferred valve geometry. The prosthesis frame may also have other regions having a preset maximum expansion diameter to avoid blockage of adjacent structures such as the coronary ostia. The prosthesis valve may be inserted into a existing artificial valve.
