ISOLATED DISEASE OF THE PULMONARY VALVE AND ARTERY *

T H E purpose of the present communication is to present seven cases of organic heart disease in which there is isolated involvement of the pulmonary artery or valve, and to indicate the importance of certain physical signs and laboratory procedures in their diagnosis. Each individual was studied while a patient in Charity Hospital at New Orleans. All but one were encountered within a few months of each other. Three patients are pre-sented as examples of congenital isolated stenosis of the pulmonary valve, two as examples of acquired pulmonary valvulitis, and two as examples of pulmonary artery aneurysm secondary to infection. CONGENITAL ISOLATED PULMONARY STENOSIS Congenital isolated pulmonary valvular stenosis is one of the rare forms of congenital heart disease. Greene et al.1 recently reviewed the 71 re-ported cases and presented four additional ones. Dyspnea is commonly present, but cyanosis is slight or absent early in life and, if present, usually makes its appearance as a late manifestation
