Preservation of a Regurgitant Quadricuspid Pulmonary Autograft by the David Procedure.

We report a case in which a quadricuspid pulmonary valve was used for the Ross operation in a young male patient. The patient demonstrated severe pulmonary autograft regurgitation due to a neosinus of Valsalva aneurysm 16 years after the primary operation. Preservation of the quadricuspid pulmonary autograft was performed by the David procedure, resulting in a competent valve function.
