title: A supernumerary cusp in the human pulmonary valve.
abstract: A supernumerary cusp of the valve of the pulmonary trunk was found in a 75-year old, male Japanese. The valve was composed of 4 cusps of different size and shape. The supernumerary cusp was located between the right and left cusps. We found this case from a series of 1,100 consecutive necropsies.
