Calcification of the Congenitally Stenotic Pulmonary Valve

Abstract
ALTHOUGH the discovery at autopsy of focal calcification in pulmonary valves of patients with congenital pulmonary stenosis is not rare1 demonstration of such calcification on roentgenograms of the chest has previously been reported in only 2 cases.2 , 3 Five patients with previously untreated congenital pulmonary-valve stenosis, each with roentgenographically visible pulmonary-valve calcification, have been seen at the Massachusetts General Hospital since January 1, 1957 (Table 1).
