Asymptomatic Isolated Valvular Pulmonary Stenosis

Abstract
ISOLATED valvular pulmonary stenosis was until recently considered to be a rare congenital cardiac anomaly. Taussig,1 in her text, states, "the author has not had the opportunity to study a proven case of pure pulmonary stenosis." Greene and his co-workers,2 in 1949, reviewed the literature and found only 68 cases proved by autopsy in which both the auricular and ventricular septums were intact. It is now realized that this entity is not rare, as evidenced by the frequent communications that have recently appeared.3 4 5 6 7 8 9 10 11 Many of the current papers4 5 6 , 9 have emphasized the physiologic studies, particularly venous cardiac catheterization, in the diagnosis . . .
