A case is described of an asymptomatic woman who had typical findings of mild pulmonic stenosis. Right heart catheterization revealed a 44 mm. Hg gradient across the pulmonary outflow tract, and a filling defect was discovered by angiography. On surgical exploration, the defect was found to be a benign cyst attached to the anterior leaflet of the pulmonary valve.
