Mild pulmonary valvular stenosis studied functionally and anatomically.

Abstract

Mild pulmonary valvular stenosis with an intact ventricular septum (also termed ‘isolated’, ‘solitary’, and ‘with normal aortic root’) has received little attention in the roentgenologic literature (KJELLBERG et coll. 1955, 1959, and GAY & FRANCH 1960). We have had twenty cases in which the diagnosis has been established by cardiac catheterization; in sixteen of these selective angiocardiography was also performed. Five of these cases were previously reported by KJELLBERG et coll. For purposes of this investigation mild solitary pulmonary stenosis was defined as : valvular stenosis by which at catheterization a peak right ventricular pressure no greater than 50 mm Hg with the patient at rest was demonstrated, and no evidence of a left-to-right shunt by oximetry. Methods and Material. The initial clinical impressions, conventional roentgenograms, cardiac catheterization data and selective angiocardiograms were studied in these 20 cases and contrasted with 15 ‘normal’ cases and 19 verified cases of moderate and marked stenosis. The ‘normal’ cases consisted of 9 cases - .~~_
