I mainly have the same questions as Debbie, has she had surgery for her pulmonary valve before?, since most adults that need replacement are because of CHD and usually had some surgeries as a child. Also as Debbie mentioned, pulmonary valves get replaced much less than other valves and the doctors with the most experience are CHD surgeons. Percutaneous Valve replacements for the pulmonary valve are approved by the FDA, but one of the criteria as far as I know is you already neeeded to have your pulm valve replaced before.
